Knockout Validated Antibodies

A high-quality antibody demonstrates target specificity, selectivity, and sensitivity, enabling it to accurately detect the protein of interest even at low expression levels. Nevertheless, cross-reactivity with off-target proteins is still a concern with some antibodies. This challenge may present issues with experimental reproducibility, as non-specific antibodies can impede scientific progress.

MBLI introduces Knockout [KO] validation as the standard of antibody confirmation.  The gene knockout validation is used to determine the function of a known sequence. By inactivating the gene that encodes the target protein, we can produce samples with a depletion of the target protein. KO validation is a highly effective technique that confirms the specificity of the antibody as depicted.
