Stachyose Tetrahydrate

Isoleucine provides a source of nitrogen for transport to the liver and kidney.

8-Anilino-1-naphthalene Sulfonic Acid is a hydrophobic polarity sensitive fluorescent dye useful as a site probe to detect conformational changes in cell and micelle membranes and molecules such as proteins. ANSA is also used as a fluorescent probe for the estimation of the critical micelle…

Pectolyase Y-23 is a highly purified maceration enzyme from Aspergillus niger. It contains two types of pectinase such as endopolygalacturonase and endo-pectin lyase in high activity. Included is a maceration stimulating factor which stimulates tissue maceration by both pectinases. Unit Definition:…

3,3-Diaminobenzidine Tetrahydrochloride is a reagent used in colorimetric analysis of Se and other metals. DAB is utilized in many applications for visualization of peroxidase activity. In the peroxidase reaction DAB serves as a hydrogen donor in the presence of peroxide; the oxidized DAB forms…

3,3',5,5'-Tetramethylbenzidine is suitable as peroxidase substrate for use in ELISA procedures. The substrate produces a soluble end product that is pale blue in color and can be read spectrophotometrically at 370 or 620-650 nm. The TMB reaction may be stopped with 2 M H2SO4 (resulting in a…

Azure B Certified is used for differentiating cellular RNA (purplish) and DNA (blue-green) in plant tissues. Useful as a stain for Negri Bodies. Can be used in the Romanowsky-type stains for blood and blood protozoa.

Adenosine-5'-triphosphate (ATP) disodium salt, >99%. Crystalline.

Guanosine-5'-triphosphate, a purine nucleotide, is required as a coenzyme for protein biosynthesis in a cell-free system. Guanosine 5′-triphosphate (GTP), a purine trinucleotide, is a substrate for RNA polymerases and a wide range of GTPase including G-protein coupled receptor (GPCR)…

G418 is an aminoglycoside related to Gentamicin and is toxic to bacteria, yeast, higher plants, mammalian cells, protozoans and helminths. It blocks polypeptide synthesis in both prokaryotic and eukaryotic cells and is useful for selection of genetically engineered eukarytoic cells in culture.

Amoxicillin is an antibacterial agent against gram-positive and gram-negative bacteria. Amoxicillin is a moderate-spectrum, β-lactam antibiotic. Amoxicillin is one of the most common antibiotics prescribed for children. It is used to study the oxygen dependent antimicrobial systems of…
