This antibody gave a positive result in ELISA against the immunizing peptide (ab33127, blue). It gave a negative result in ELISA against the non-modified equivalent peptide (ab42660, purple). This indicates that it is specific for the modified peptide.
CC/IF image of ab31893 stained human HepG2 cells. The cells were 4% PFA fixed (10 min), permabilised in 0.1% PBS-Tween (20 min) and incubated with the antibody (ab31893, 5µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue). This antibody also gave a positive IF result in HeLa, HEK 293 and MCF7 cells. However, this Fast-Track antibody is not yet fully characterised. This image represents inconclusive preliminary data.
