Knockout (KO) Validated Antibodies

Highly Validated Antibodies For Results You Can Trust

PrecisionAb Antibodies

In accordance with recommendations by the International Working Group for Antibody Validation (Uhlen et al. 2016), we use various methods to validate PrecisionAb Antibodies. Our methods include Knockout (KO) antibody validation.

Knockout Validation

These include genetic strategies where the expression of the target protein is compared between the wild type cell line and the cell line in which gene encoding the protein is knocked out using CRISPR/Cas9 (Figure 1). In the KO cell line, a specific antibody doesn’t produce the signal demonstrating that the antibody detects the intended target protein.

Probed with A, Mouse Anti-PFKP Antibody (VMA00145) and B, hFAB Rhodamine Anti-Tubulin Primary Antibody (12004166). C, normalized signal intensity of PFKP from CRISPR knockout and wild type lysates. Signal intensity was normalized to the tubulin signal.

KO Validated PrecisionAb Antibodies

Antibodies that have been KO validated are marked with a KO validation flag and a PrecisionAb enhanced validation logo on product webpages.
