Cat.No. : PCSK9-352H
Product Overview : Recombinant Human PCSK9 Protein, His & Avi-tagged, Biotinylated is expressed from human HEK293 cells. It contains AA Gln 31 - Gln 692 (Accession # AAI66619). Predicted N-terminus: Gln 31. This protein carries an Avi tag at the C-terminus, followed by a polyhistidine tag. The protein has a calculated MW of 72.0 kDa. The protein migrates as 20 kDa and 66 kDa on a SDS-PAGE gel under reducing (R) condition due to glycosylation and proteolytic digestion. The biotin to protein ratio is 0.5-1 as determined by the HABA assay.
Source : HEK293
Species : Human
Tag : His & Avi
Form : Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
Bio-activity : Immobilized Human LDL R, His Tag at 10 μg/mL (100 μL/well) can bind Recombinant Human PCSK9 Protein, His & Avi-tagged, Biotinylated with a linear range of 2-31 ng/mL (QC tested).
Recombinant Human PCSK9 Protein, His & Avi-tagged, Biotinylated can bind anti-Human PCSK9 Mab, Human IgG1 with a linear range of 0.05-1.5 ng/mL. The biotinylated PCSK9 is coated at 1 ug/mL (100 uL/well) on a streptavidin coated plates (Routinely tested).
Immobilized Human VLDL R, His Tag at 5 μg/mL (100 μL/well) can bind Recombinant Human PCSK9 Protein, His & Avi-tagged, Biotinylated with a linear range of 10-156 ng/mL (Routinely tested).
FACS analysis shows that Biotinylated Human PCSK9, His Tag (Cat. No. PC9-H82E7) inhibits LDL uptake in HepG2 cells. The EC50 for this effect is 1.502-2.378 μg/mL.
Molecular Mass : 72.0 kDa
Protein length : Gln 31 - Gln 692
Endotoxin : Less than 1.0 EU per μg by the LAL method.
Purity : >92% as determined by reduced SDS-PAGE.
Notes : Please avoid repeated freeze-thaw cycles.
Stability : No activity loss is observed after storage at:
4-8 centigrade for 12 months in lyophilized state;
-70 centigrade for 3 months under sterile conditions after reconstitution.
Storage : For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4 centigrade before opening to recover the entire contents.
