Recombinant Human PCSK9 Protein, His & Avi-tagged, Biotinylated
Welcome! For price inquiries, please feel free to contact us through the form below. We will get back to you as soon as possible.
|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.|
|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.
