Supplier: MP Biomedicals
Description: Folinic acid calcium salt, pentahydrate offsets the effects of folic acid antagonists that act by binding dihydrofolate reductase and blocking the conversion of folic acid to tetrahydrofolate.

Supplier: MP Biomedicals
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.

Supplier: SIGMA ALDRICH MICROSCOPY
Description: Poly-L-lysine is a positively charged amino acid polymer with approximately one HBr per lysine residue. The hydrobromide allows the poly-L-lysine to be in a crystalline form soluble in water. A small amount of product may be found in the beta structure because the HBr interferes with hydrogen bonding between amino and either the carboxyl groups or N or O containing moieties.

Description: Poly-L-Lysine is typically used as a coating substrate for culture dishes, slides, etc.

Catalog Number: (ICNA0215269080)
Supplier: MP Biomedicals
Description: Poly-L-lysine is a nonspecific attachment factor for cells useful in promoting cell adhesion to solid substrates. It enhances electrostatic interaction between negatively charged ions of the cell membrane and the culture surface. When adsorbed to the culture surface, poly-L-lysine increases the number of positively charged sites available for cell binding. Polymers of both D- and L-lysine are used to coat solid surfaces.
UOM: 1 * 100 mg


Supplier: MP Biomedicals
Description: There is approximately one HBr or HCl per lysine unit. The HBr/HCl allows it to be a crystalline solid and soluble in water. To remove the HBr/HCl, solubilise the product in a neutral buffer and dialyse away the salts.
