Description_x000D_ General description_x000D_ Neuraminidase enzymes are glycoside hydrolase enzymes that catalyze hydrolysis of terminal sialic acid residues. The most well-known are the viral nearamidases, which promote influenza virus release._x000D_ Application_x000D_ Agarose-linked neuraminidase from Clostridium perfringens can be used for the detection of total and desialylated sex hormone-binding globulin in human serum samples._x000D_ Neuraminidase from Clostridium perfringens has been used in a study to assess a genetic polymorphism of human serum glycoprotein (inter-α-trypsin-inhibitor). It has also been used in a study to investigate the inhibition of neuraminidase by chemically sulphated glycopeptides._x000D_ Unit Definition_x000D_ One unit will liberate 1.0 μmole of N-acetylneuraminic acid per min at pH 5.0 at 37 °C using NAN-lactose or bovine submaxillary mucin, unless otherwise specified. Prices based on units using NAN-lactose as substrate._x000D_ Physical form_x000D_ Suspension in 2.0 M (NH4)2SO4 solution, pH 7.0._x000D_ Preparation Note_x000D_ Prepared from Neuraminidase, Type VI (N 3001).
