Peroxidase, MP Biomedicals

Référence Produit: (ICNA0215003810)
Fournisseur: MP Biomedicals
Description: Soluble in distilled water. Soluble in 0,1 M potassium phosphate buffer, pH 6,0 (monobasic potassium phosphate adjusted to pH 6,0 with 1,0 M potassium hydroxide) (10 mg/ml yields a clear, red-brown solution). Solutions of HRP can be kept refrigerated for up to a year while maintaining practically undiminished activity. Optimal pH is 6,0 to 6,5 (activity at pH 7,5 is 84% of the maximum). The enzyme is most stable in the pH range of 5,0 to 9,0 (Lit.).

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.

Papain, MP Biomedicals

Fournisseur: MP Biomedicals
Description: Activators: Papain is activated by cysteine, sulphide, sulphite and more. It is enhanced when heavy metal binding agents such as EDTA are also present. N-bromosuccinimide enhances the activity. Inhibitors: Substances which react with sulphydryl groups including heavy metals, carbonyl reagents. Aldehydes are papain inhibitors. Benzoylamidoacetonitrile is an inhibitor. See Shapira and Arnon (1967a and b) on antibody inhibitors. Papain may be inactivated by H₂O₂ generated by γ-irradiation of H₂O<sup>−</sup> the active SH group being oxidised to sulphenic acid. Specific inhibitors are AEBSF, antipain, cystatin, E-64, leupeptin, PMSF, TLCK and TPCK.
