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.
Recombinant PCSK9 was further labled by Biotin for detection by avidin conjugated secondary probes.
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
Biotinylated recombinant PCSK9 was designed to be used in single step detection in ELISA ,WB
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
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
binding affinity at acidic
internalized PCSK9 dissociates from recycling ldl receptors in PCSK9-resistant sv-589 fibroblasts
