Biotinylated anti-CD20 IgG antibody is a purified recombinant antibody which recognizes human CD20 antigen. This antibody has been tested for specific binding to purified human CD20 protein.
assay conditions: Functional validation: The antibody was validated by ELISA using a purified CD20 antigen. The CD20 protein was coated onto a 96-well plate overnight at 4°C (50 ul/well at a concentration of 4 ug/ml in PBS). The plate was washed 3 times with Immuno Buffer 1 (BPS Bioscience #79311) and blocked using 100 ul of Blocking Buffer 2 (BPS Bioscience #79728) for 1 hour at room temperature. After removing the blocking buffer, 50 ul/well of purified biotinylated anti-CD20 antibody (BPS Bioscience #101207), serially diluted in Blocking Buffer 2, was added for 30 minutes at room temperature. After 3 more washes, the plate was incubated with Streptavidin-HRP, washed, and incubated with the Colorimetric HRP substrate. The reaction was stopped, and absorbance was read at 450 nm. The Blank value was subtracted from all values.
