Neuraminidase, MP Biomedicals

Fournisseur: MP Biomedicals
Description: Neuraminidase (Sialidase: Acylneuraminyl hydrolase; EC 3.2.1.18) From Arthrobacter ureafaciens lyophilised powder with salts. The salts are composed of sodium-potassium phosphate to give a solution of 10 mM phosphate buffer (pH 7) when enzyme is reconstituted with water to make activity of 1 unit per ml. Activity: >60 units/mg protein for NAN-lactose >25 units/mg protein for bovine submaxillary mucin >20 units/mg protein for colominic acid Protein is determined by the method of Lowry et al. with bovine albumin as a standard.6 Unit definition: One unit will liberate 1,0 µmole of N-acetyl-neuraminic acid (NANA) per minute at pH 5,0 at 37 °C, using either one NAN-lactose, bovine submaxillary mucin, or colominic acid as a substrate.

Poly-L-lysine hydrobromide, MP Biomedicals

Fournisseur: 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.

Elastase, MP Biomedicals

Fournisseur: MP Biomedicals
Description: Elastase is prepared from porcine pancreas. It is lyophilised and water soluble. Elastase is chromatographically prepared by the method of Narayanan and Anwar. In the method, 2 times crystalline elastase is adsorbed on a column of DEAE-Sephadex A50 to separate elastase and non-specific protein components. The elastase component is further purified by chromatography on a column of CM-Cellulose using a sodium chloride gradient to elute the elastase. The latter is dialysed until chloride-free and then lyophilised. During its preparation the elastase is held below a pH of 5,5 for greater than 24 hours. Two times crystallised from the euglobin fraction of porcine pancreas by the method of Lewis et al. Does not contain trypsin or chymotrypsin.
