Anti-GAPDH (GA1R) loading control is a truly unique mAb, as it gives clear Western Blot results at dilution ratios as high as 1:100,000. It is also the only GAPDH mAb in the market that recognizes the GAPDH protein from the following species: BL-21 bacteria, Sf9 insect, Saccharomyces cerevisiae (yeast), plus tissues from human, mouse, rat, rabbit, chicken, hamster, and potentially many more species.
