Description générale

Calorimetry studies show that the two lectin-like domains flanking the central catalytic domain of Neuraminidase serve as the recognition and binding sites for sialic acid-containing substrates.
Neuraminidase enzymes are hydrolase enzymes that promote influenza virus release from infected cells and facilitate virus spread.

Application

Neuraminidase from Vibrio cholera has been used in a study to describe a five-step purification method. It has also been used in a study to investigate modification of leukemia L1210 tumor cells.
Neurminidase is used as a cell-surface probe for glycoconjugate distribution and in substrate specificity studies.

Qualité

Preservative free.

Définition de l'unité

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.

Forme physique

Solution in 50 mM sodium acetate, pH 5.5, containing 0.15 M sodium chloride and 4 mM calcium chloride, 0.2 μm filtered..

Notes préparatoires

A further purification by affinity chromatography of our Type III.

Vibrio cholerae neuraminidase (VCNA) plays a significant role in the pathogenesis of cholera by removing sialic acid from higher order gangliosides to unmask GM1, the receptor for cholera toxin. We previously showed that the structure of VCNA is composed of

A selective and potent inhibitor of neuraminidases, a hydrolase that is responsible for processing sialylated glycoconjugates, is a promising drug candidate for various infective diseases. The current study demonstrates that the use of an aglycone-focused library of 2-difluoromethylphenyl α-sialosides is
