性能参数

表达区间及表达系统(Source

Recombinant Human PCSK9 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Gln31-Gln692.[Accession | Q8NBP7-1]

分子量大小(Molecular Weight

Due to autocatalytic cleavage, the protein release the pro-form (59 kDa) and mature form (14 kDa). Due to glycosylation, the protein migrates to 65-68 kDa (pro-form) and 15kDa (mature form) based on Tris-Bis PAGE result.

内毒素(Endotoxin

Less than 1EU per μg by the LAL method.

纯度(Purity

> 95% as determined by Tris-Bis PAGE and HPLC
