Recombinant Protein;100UG;Biotinylated Recombinant Protein L, His,Avitag™, also known as Recombinant Peptostreptococcus magnus Protein L, was expressed in E.Coli at ACRObiosystems. ;This protein carries a polyhistidine tag at the N-terminus, followed by an Avi tag (Avitag™). The protein has a calculated MW of 43.7 kDa. The protein migrates as 50 kDa under reducing (R) condition (SDS-PAGE). This protein can bind to VL-Kappa.;Immobilized Mouse Human chimeric Anti-BCMA mAb (Aa01, Mouse IgG1) at 2 μg/mL (100 μL/well) can bind Biotinylated Recombinant Protein L, His,Avitag (Cat. No. RPL-P81Q7) with a linear range of 0.2-2 ng/mL (QC tested).;Immobilized Ipilimumab at 2 μg/mL (100 μL/well) can bind Biotinylated Recombinant Protein L, His,Avitag (Cat. No. RPL-P81Q7) with a linear range of 0.2-2 ng/mL (Routinely tested).;2e5 of anti-BCMA CAR-293 cells were stained with 100 μL of 10 μg/mL of Biotinylated Recombinant Protein L, His,
