Human Protein Atlas Formal Validation Data - Genetic and Tagged Protein Strategies

Contribution from The Human Protein Atlas (proteinatlas.org) — October 16, 2015

The Human Protein Atlas has successfully tested the Anti-CTBP1 antibody (HPA018987) in siRNA transfected U-2 OS cells and HeLa cell lines stably expressing GFP-tagged target protein.

A. To validate the subcellular localization of the Anti-CTBP1 antibody (HPA018987), determined by immunofluorescence, the staining procedure was repeated on siRNA transfected U-2 OS cells. The assay was performed in duplicates using siRNA:s from two different providers (siRNA 1 and siRNA 2) and the results were compared to negative control cells transfected with scrambled siRNA.

Negative control (scrambled)                                     siRNA transfected U-2 OS cells

The images show signal downregulation > 25% compared to the negative control (scrambled). Relative Fluorescence Intensity (RFI) denotes the percentage of remaining staining intensity after siRNA down regulation.

B. The Anti-CTBP1 antibody (HPA018987) was tested in Western blot using siRNA transfected U-2 OS cells, from two different providers (siRNA 1 and siRNA 2), and the result shows specific downregulation in both siRNA lanes compared to the control (scrambled).

Lane 2: siRNA 1
Lane 3: siRNA 2
Lane 4: scrambled

C. The Anti-CTBP1 antibody (HPA018987) was analyzed in HeLa cell lines stably expressing GFP-tagged target protein and the result shows that the antibody staining overlaps with GFP tagged protein.
