Product Description:

2,6-dichlorophenolindophenol ( DCPIP ) is a blue chemical compound used as a redox dye. In Oxidized form DCPIP is blue;whereas in reduced form DCPIP is colorless.The rate of photosynthesis can be measured by the rate at which this dye changes color (is reduced) when exposed to light in a photosynthetic system. This reaction is reversible, as colorless DCPIP can be reoxidized to blue. Blue redox indicator dye used for the determination of Vitamin C (ascorbic acid), which when Vitamin C is present reduces to a colorless hydroxy compound. May be used as an electron acceptor and to stain glutathione reductase electrophoresis gels. Also known as Tillman's reagent.

Applications:

 

2,6-dichlorophenolindophenol (DCPIP) is used as a substitute for NADP+. The dye changes color when it is reduced, due to its chemical structure. The rate of photosynthesis light-dependent reaction can be measured with this property of DCPIP, because one of the stages of the light reaction is an electron transport chain that normally ends with the reduction of NADP+. When DCPIP is present, it also gets reduced by the light reaction. The amount of DCPIP reduced can be found by measuring the solution's light transmittance with a spectrophotometer. 2,6-dichlorophenolindophenol sodium salt is a redox dye commonly used as a monitor of the light reactions in photosynthesis because it is an electron acceptor that is blue when oxidized and colorless when reduced. It is part of the Hill reagents family. DCPIP can also be used as an indicator for Vitamin C. If vitamin C, which is a good reducing agent, is present, the blue dye, which turns pink in acid conditions, is reduced to a colorless compound by ascorbic acid. 2,6-Dichloroindophenol sodium salt hydrate is suitable for vitamin C determination. It acts as a redox dye to investigate the efficiency of gold nanoparticles (Au-NP) for the enzymatic activity of glucose oxidase. It is also used to compose UVB specific dosimeter and to measure the rate of photosynthesis. It serves as a good reducing agent.

C.A.S. No.  : 12627-53-1

Specifications: 

Product Description:

Leishman's stain is applied in conventional staining techniques to uniformly stain chromosomes. These techniques leave centromers constricted, thus enabling the measurement of chromosome length, centromeric position, and arm ratio. Slides can be easily destained and banded by most banding procedures.

Applications:

 

Leishman's Stain is used generally in hematology and tropical medicine to differentiate and identify leucocytes, malarial parasites and trypanosomes. . Leishman's stain, also Leishman stain, is used in microscopy for staining blood smears. It provides excellent stain quality. Leishman’s staining method for thin and thick smears is a good alternative to Giemsa’s stain for identifying Plasmodium parasites. The Leishman method is superior for visualization of red and white blood cell morphology.A number of Romanowsky stains like Field’s, Giemsa’s, Wright’s and Leishman’s are suitable for staining the smears. Thick films are ideally stained by the rapid Field’s technique or Giemsa’s stain for screening of parasites. The sensitivity of a thick blood film is 5-10 parasites/µl. Thin blood films stained by Giemsa’s or Leishman’s stain are useful for specification of parasites and for the stippling of infected red cells and have a sensitivity of 200 parasites/µl. The optimal pH of the stain is 7.2.

Specification:
Product Description:

Bromothymol blue is a large compound with a molecular weight of 625 g/mol. It contains three aromatic benzene rings. The first benzene ring has a thym group attached (the 'thym' part of the name), a sulfur with two oxygen atoms double bonded to it, and another oxygen single bonded to it. The second and third benzene rings each have a bromine (the 'bromo' part of the name), alcohol (the 'ol' suffix), a tert-butyl group, and a methyl group. This 0.1% aqueous bromothymol blue solution (also known as Bromthymol Blue) is a commonly used pH indicator. Bromthymol blue changes color over a pH range from 6.0 (yellow) to 7.6 (blue). It is a good indicator of dissolved carbon dioxide (CO2) and other weakly acidic solutions. Despite its name, bromothymol blue solution may sometimes appear yellow or reddish depending on the pH of the stock water used to prepare this pH indicator solution. Low levels of carbon dioxide or acid in solution with bromothymol blue indicator will appear blue. As the level of carbon dioxide or acid increases, the solution will gradually take on a yellow tint. This makes bromothymol blue ideal for biology experiments to indicate photosynthetic activity (solution turns blue as plants use up carbon dioxide) or respiratory activity (solution turns yellow as carbon dioxide content increases).

Product      : Giemsa Stain
C.A.S. No.  : 51811-82-6

Specifications: 

Product Description:

Giemsa Stain is a laboratory reagent and stain for microscopy. A compound of eosin with methylene blue and its oxidation products. When blood films are stained using Giemsa stain, the nucleus and cytoplasm of white blood cells take on a characteristic blue or pink coloration. Giemsa stain functions by rearranging chromatin and inducing G bands producing a high quality stain for chromatin and the nuclear membrane. Giemsa stain is used to differentiate nuclear and/or cytoplasmic morphology of platelets, RBCs, WBCs, and parasites (1,2). The most dependable stain for blood parasites, particularly in thick films, is Giemsa stain containing azure B. Liquid stock is available commercially. The stain must be diluted for use with water buffered to pH 6.8 or 7.0 to 7.2, depending on the specific technique used.

Applications:

 

Giemsa and May Grünwald solutions are intended for use in staining blood films or bone marrow films. Solutions are for “In Vitro Diagnostic Use.” Giemsa stain is a buffered thiazine-eosinate solution designed to provide coloration of blood cells similar to the original product described by Giemsa. It may be used separately or in combination with a May Grünwald Stain, also available from Sigma-Aldrich. Giemsa stain is a biological stain for thin blood films to differentiate leucocytes, for thick blood films to show malarial parasites, and for bone marrow to show cell morphology. It is also used as a chromosome stain and to differentiate nuclear morphology of platelets, RBCs, and other cell types. Giemsa Stain was designed primarily for the demonstration of parasites in malaria, but it was also employed in histology because of the high-quality staining of the chromatin and the nuclear membrane, the metachromasia of some cellular components, and the different qualities of cytoplasmic staining depending on the cell type. The use of methylene azure and its mixture with methylene blue to form an eosinate made stable the stain and its results. Giemsa's stain is regarded as the world's standard diagnostic technique for malaria's plasmodium, and it is also the basic stain for classifying lymphomas in the Kiel classification.

Product Description:

Chemicals and substances that impart color including soluble dyes and insoluble pigments. They are used in INKS; PAINTS; and as INDICATORS AND REAGENTS.

Applications:

 

METHYL RED IS BOUND TO BOVINE SERUM ALBUMIN. Urine pH is usually measured with a reagent test strip. Most commonly, the double indicators methyl red is used in the reagent strips to give a broad range of colors at different pH values. In conjunction with other specific urine and plasma measurements, urine pH is often invaluable in diagnosing systemic acid-base disorders. By itself, however, urine pH provides little useful diagnostic information. The normal range for urine pH is 4.5 to 7.8. Methyl red test is a quantitative test for acid production, requiring positive organisms to produce strong acid (lactic, formic) from glucose through the mixed acid fermentation pathway. Since many species of Enterobacteriaceae may produce sufficient quantities of strong acid that can be detected by methyl red indicator during the initial phases of incubation. Only organisms that can maintain this low pH after prolonged incubation (48-72 hours) and overcoming the pH buffering system of the medium can be called as methyl red positive. The development of stable red colour in surface of the medium indicates sufficient acid production to lower pH to 4.4 and constitutes positive test. While other organisms may produce lesser quantities of acid from test substrate, an intermediate orange colour between yellow and red may developed, this indicate negative test.

Trypan Blue is an acid azo dye commonly used as a stain to distinguish viable from non-viable cells. It turns dead cells blue and viable cells unstained. It is a known animal carcinogen and an experimental teratogen. A dye obtained from tolidine that is absorbed by the macrophages of the reticuloendothelial system and is therefore used for staining cells in biological research. Trypan blue is an antiprotozoal drug first used to treat Babesia infection in 1909 and still commonly used to treat Babesia canis. The complex chemical structure has been progressively simplified, yielding such other widely used drugs as imidocarb.Applications:Trypan Blue is a water-soluble dye used for the dye exclusion test for cell viability to distinguish between viable and nonviable cells by seeping into nonviable cells with damaged plasma membranes causing them to appear blue.Trypan blue is a dye used to distinguish between live and dead cells. It is a vital stain that is not absorbed by healthy viable cells, but stains cells with a damaged cell membrane. This way, only dead cells can be counted. The method is sometimes referred to as the dye exclusion method.Trypan Blue Solution, is routinely used as a cell stain to assess cell viability using the dye exclusion test. This test is often performed while counting cells with the hemocytometer during routine subculturing, but can be performed any time cell viability needs to be determined quickly and accurately. The dye exclusion test is based upon the concept that viable cells do not take up impermeable dyes (like Trypan Blue), but dead cells are permeable and take up the dye.Trypan Blue is recommended for counting viable mammalian cells. Viable cell counts should be performed where a decrease in cell viability may be expected, for example, when working with cryopreserved cells or cells manipulated ex vivo.
