This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 22.2 kDa. The protein migrates as 30-35 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

FITC-Labeled Human BCMA, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.
The purity of FITC-Labeled Human BCMA, His Tag (Cat. No. BCA-HF2H3) is more than 90% and the molecular weight of this protein is around 24-34 kDa verified by SEC-MALS.
2e5 of 293 CAR cells transfected with anti-BCMA-scFv were stained with 100 μL of 1 μg/mL of FITC-Labeled Human BCMA, His Tag (Cat. No. BCA-HF2H3) and negative control protein respectively (Fig. C and B), and non-transfected 293 cells were used as a control (Fig. A), FITC signal was used to evaluate the binding activity (QC tested).
5e5 of PBMCs were stained with FITC-Labeled Human BCMA, His Tag (Cat. No. BCA-HF2H3) and anti-CD3 antibody, washed and then analyzed with FACS. PE signal was used to evaluate the expression of CD3+ T cells in PBMCs, and FITC signal was used to evaluate the non-specific binding activity to PBMCs (QC tested).
