Immobilized Anti-CD4 Antibody (Ibalizumab-IgG4) at 1 μg/mL (100 μL/well) can bind Alexa Fluor 488-Labeled Human CD4 Protein, His Tag (Cat. No. CD4-HA2H7) with a linear range of 0.2-16 ng/mL (Routinely tested). Labeling with fluorescent dyes did not affect their activity.
1e5 of Mouse Anti-CD4 antibody coupled beads (5.5 μm) were stained with different concentration of Alexa Fluor 488-Labeled Human CD4 Protein, His Tag (Cat. No. CD4-HA2H7) and negative control protein respectively, AF488 signal was used to evaluate the binding activity (QC tested).
