Description:
Poly-L-lysine is a positively charged amino acid polymer. Poly-lysine binds to DNA, red cell membrane and any negatively charged protein. It is typically used as a coating substrate for culture dishes, slides, etc. It enhances electrostatic interaction between negatively charged ions of the cell membrane and the culture surface. When adsorbed to the culture surface, poly-lysine increases the number of positively charged sites available for cell binding.
Description:
Avidin is a basic glycoprotein isolated from raw egg white. It exhibits high binding affinity for biotin and is capable of producing biotin deficiency in rats and chicks. It also occurs in the white portion of eggs and the oviducts of birds and amphibia. It is destroyed by cooking or irradiation.
Description:
Penicillin G potassium Salt is a salt of Penicillin G. Penicillin G is a hydrophobic, β-lactam antibiotic produced by Penicillium spp. Penicillin G is also known as benzylpenicillin and contains a 6’ phenylacetyl side chain. In acid aqueous solutions, Penicillin is reported to decompose into penillic acid and penilloic acid.

Description:
Trypsin is a porcine pancreas-derived enzyme that is commonly used for the dissociation and disaggregation of anchorage-dependent mammalian cells and tissues. The concentration of trypsin necessary to dislodge cells from their substrate is dependent primarily on the cell type and the age of the culture.
Description:
Pristane is a natural saturated terpenoid alkane obtained primarily from shark liver oil. Pristane is used as a biological marker. It known to induce autoimmune diseases in rodents. It is used in research to understand the pathogenesis of rheumatoid arthritis and lupus, as a non-antigenic arthritogenic adjuvant and plasmacytomas. Store at Room Temperature(15-30 °C)
Description:
Use of dextrans as long and hydrophilic spacer arms improves the performance of immobilized proteins acting on macromolecules. Dextrans are used in many applications as platelet aggregants, plasma volume extenders, osmotic pressure regulators, stabilizers, organ separation media, matrix components, copolymers, microcarriers, binding agents, viscosity modifiers, antithrombotics, lubricants and physical structure components. They may be used as long hydrophilic spacer arms to improve the performance (freedom of movement) of conjugated/bound proteins. Dextrans may be derivatized for use in biosensor systems. Dextran is branched polysaccharide made up of linear α (1→6) linked glucose units and α (1→3) link initiated branches; it ranges in size from 10,000 to 150,000 Kd.Depending upon its molecular weight it has different uses in different fields. Physical Appearance: White powder Solubility: Very soluble in water (50 mg/mL), slightly soluble in alcohol
Description:
GeneClean® Turbo kit is used for purification of DNA fragments of sizes 0.1 to 300 kb from agarose gels, PCR reactions and other enzymatic solutions. Purified DNA can be used in enzymatic reactions, conventional or automated sequencing, cloning and microarray analysis.
Description:
Nutrient Broth is a general purpose medium used for cultivating a broad variety of fastidious and non-fastidious microorganisms with non-exacting nutritional requirements.
Description:
Role of a balanced salt solution in cell culture is multifaceted and can be divided into four principal functions: 1. Serves as an irrigating, transporting and diluting fluid while maintaining intra- and extracellular osmotic balance; 2. Provides cells with water and certain bulk inorganic ions essential for normal cell metabolism; 3. Combined with a carbohydrate, such as glucose, provides the principal energy source for cell metabolism; 4. Provides a buffering system to maintain the medium within the physiological pH range (7.2 - 7.6)
