C. Perfringens Neuraminidase Protein, C.perfringens, Recombinant (His Tag)
别称:NA Protein, C.perfringens
纯度:> 97 % as determined by SDS-PAGE
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 150,000 pmoles/min/μg (Activity of this protein is much better than the world's famous brand) as measured under the described conditions .
蛋白构建:A DNA sequence encoding the C. Perfringens neuraminidase (P10481.1) (Cys 2-Gln 382) was expressed, with a N-terminal polyhistidine tag.
NP No.:P10481.1
表达宿主:E. coli
种属:C.perfringens
预测 N 端:Met
分子量:The recombinant C. Perfringens neuraminidase consisting of 388 amino acids and has a calculated molecular mass of 43.6 kDa. It migrates as an approximately 40 kDa in SDS-PAGE under reducing conditions.
缓冲液:Lyophilized from sterile PBS, pH 7.4.
Please contact us for any concerns or special requirements.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
运输方式:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
稳定性 & 储存条件:Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
复溶:A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
