Human CD19 (20-291), Fc Tag, premium grade on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 90%.
The purity of Human CD19 (20-291), Fc Tag, premium grade (Cat. No. CD9-H5251) is more than 95% and the molecular weight of this protein is around 140-160 kDa verified by SEC-MALS.
Immobilized FMC63 (Mouse IgG2a) at 1 μg/mL (100 μL/well) can bind Human CD19 (20-291), Fc Tag, premium grade (Cat. No. CD9-H5251) with a linear range of 1-31 ng/mL (QC tested).
Immobilized Human CD19 (20-291), Fc Tag, premium grade (Cat. No. CD9-H5251) at 5 μg/mL (100 μL/well) can bind FMC63 (Mouse IgG2a) with a linear range of 0.6-5 ng/mL (Routinely tested).
Human CD19 (20-291), Fc Tag, premium grade (Cat. No. CD9-H5251) captured on CM5 chip via Anti-Human lgG Fc antibodies surface, can bind FMC63 MAb (Mouse lgG2a) with an affinity constant of 0.17 nM as determined in a SPR assay (Biacore T200) (Routinely tested).
Bispecific T cell Engager (CD3 X CD19) captured on CM5 chip, can bind Human CD19 (20-291), Fc Tag, premium grade (Cat. No. CD9-H5251) with an affinity constant of 0.93 nM as determined in a SPR assay (Biacore T200) (Routinely tested).
Loaded Human CD19 (20-291), Fc Tag, premium grade (Cat. No. CD9-H5251) on AHC Biosensor, can bind FMC63 MAb (Mouse lgG2a) with an affinity constant of 0.483 nM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).
293 cells were transfected with FMC63-scFv and RFP tag. 2e5 of the cells were first stained with B. Human CD19 (20-291), Fc Tag, premium grade (Cat. No. CD9-H5251, 3 µg/mL) and C. Human Fc Tag Protein Control, followed by FITC-conjugated Anti-human IgG Fc Antibody. A. Non-transfected 293 cells and C. Human Fc Tag Protein Control were used as negative control. RFP was used to evaluate CAR (anti-CD19-scFv) expression and FITC was used to evaluate the binding activity of Human CD19 (20-291), Fc Tag, premium grade (Cat. No. CD9-H5251).
