Domain  : 
Gene  :  PCSK9
Catalog no. :  RKQ8NBP7



Optimized DNA sequence  encoding  extracellular domain of Human Proprotein convertase subtilisin/kexin type 9 (PCSK9) (GLN31 - GLN692) including a C-terminal His tag was expressed in HEK293 cells.

Molecular weight:

Recombinant human PCSK9 is a protein consisting of 670 amino acid residue subunits,due to glycosylation migrates as an approximately 20kDa & 60kDa protein on reduced SDS-PAGE.

>95%, as determined by SDS-PAGE and HPLC
Biological Activity:
The activity was tested by the ability of immobilized recombinant Human PCSK9  to bind recombinant human LDLR within a linear range of 10-100ng/ml in ELISA.
Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).

Recombinant Human PSCK9 is lyophilized  from 0.2 μm filtered PBS solution,  pH7.2 ,  5% Trehalose.

Recombinant  PCSK9 can be stored in working aliquots at 2° - 8° C for one month, or at -20°C to -70°C for twelve months.

Avoid repeated freeze/thaw cycles.

LDLR also binds proprotein convertase subtilisin/kexin type-9 (PCSK9), a secreted member of the mammalian proprotein convertase family of serine endoproteases . Bound PCSK9 disrupts the normal endocytic recycling itinerary of the LDLR and directs the receptor for degradation in endolysosomal compartments. PCSK9 binds in a Ca2+-dependent manner to the first of three Ca2+- binding EGF-like repeats (EGF-A) in the EGF precursor homology domain of LDLR and demonstrates increased binding affinity at acidic pH.
