일반 설명

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.

애플리케이션

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.

품질

Preservative free.

단위 정의

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.

물리적 형태

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

Polyomaviruses are small, non-enveloped DNA tumor viruses that cause serious disease in immunosuppressed people, including progressive multifocal leukoencephalopathy (PML) in patients infected with JC polyomavirus, but the molecular events mediating polyomavirus entry are poorly understood. Through genetic knockdown approaches, we
