内毒素

< 1.0 EU per μg of the protein as determined by the LAL method

生物活性

Measured by its ability to cleave a fluorogenic substrate, 2'-(4-Methylumbelliferyl)-α-D-N-acetylneuraminic acid.
The specific activity is > 1,000 U.
One unit is defined as the amount of enzyme required to cleave 1 nmole of 2'-(4-Methylumbelliferyl)-α-D-N-acetylneuraminic acid per minute at pH 7.5 at 37℃.

蛋白构建

A DNA sequence encoding the Influenza A virus (A/Babol/36/2005 (H3N2)) neuraminidase (ACN50232.1) (His 36-Pro 459) was expressed, the cell lysates are collected, and bio-activity was tested. There is an amino acid change from Histidine to Tyrosine (H274Y mutation) in NA / Neuraminidase.

NP No.
