Recombinant Protein;500UG;Human CD20 Full Length, His Tag, HEK293 (CD0-H52H3) is expressed from human 293 cells (HEK293). It contains AA Met 1 - Pro 297 (Accession # P11836-1).;This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 35.2 kDa. The protein migrates as 40 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.;Immobilized Rituximab at 2 μg/mL (100 μL/well) can bind Human CD20 Full Length, His Tag, HEK293 (Cat. No. CD0-H52H3) with a linear range of 2-16 ng/mL (in presence of DDM and CHS) (QC tested).;Immobilized Ofatumumab at 2 μg/mL (100 μL/well) can bind Human CD20 Full Length, His Tag, HEK293 (Cat. No. CD0-H52H3) with a linear range of 1-20 ng/mL (in presence of DDM and CHS) (QC tested).;MabThera (Rituximab) captured on CM5 chip via Anti-human IgG Fc antibodies surface can bind Human CD20 Full Length, His Tag, HEK293 (Cat. No. CD0-H52H3) with an affinity constant of 1.77 nM as determined in a SPR assay (in presence of DD
