Source |
Recombinant Human PCSK9 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Gln31-Gln692.[Accession | Q8NBP7-1] |
|
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. |
|
Endotoxin |
Less than 1EU per μg by the LAL method. |
|
Purity |
> 95% as determined by Tris-Bis PAGE and HPLC |
|
Activity |
ELISA Data: Immobilized Human PCSK9, His Tag at 2μg/ml (100μl/Well) on the plate. Dose response curve for Anti-PCSK9 antibody, hFc Tag with the EC50 of 0.16μg/ml determined by ELISA . SPR Data :Human LDLR, His Tag immobilized on CM5 Chip can bind Human PCSK9, His Tag with an affinity constant of 0.35 nM as determined in SPR assay (Biacore T200). |
