Recombinant Protein;200UG;Biotinylated Human CD19 (20-291), His,Avitag (CD9-H82E9) is expressed from human 293 cells (HEK293). It contains AA Pro 20 - Lys 291 (Accession # P15391-1).;This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag. The protein has a calculated MW of 33.7 kDa. The protein migrates as 50-65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.;Immobilized Monoclonal Anti-Human CD19 Antibody, Mouse IgG2a at 2 μg/mL (100 μL/well) can bind Biotinylated Human CD19 (20-291), His,Avitag (Cat. No. CD9-H82E9) with a linear range of 1-31 ng/mL (Routinely tested).;Immobilized Biotinylated Human CD19 (20-291), His,Avitag (Cat. No. CD9-H82E9) at 1 μg/mL (100 μL/well) on Streptavidin (Cat. No. STN-N5116) precoated (0.5 μg/well) plate, can bind Monoclonal Anti-Human CD19 Antibody, Mouse IgG2a with a linear range of 0.1-6 ng/mL (Routinely tested).;Biotinylated Human CD19 (20-291), His,Avitag (Cat.
