Western blot - Anti-S100A4 antibody [EPR14639(2)] - BSA and Azide free (AB220213)

False colour image of Western blot : Anti-S100A4 antibody [EPR14639(2)] staining at 1/1000 dilution, shown in green; loading control ab7291 (Mouse anti-Alpha Tubulin [DM1A]) staining at 1/20000 dilution, shown in red. In Western blot, ab197896 was shown to bind specifically to S100A4. A band was observed at 11 kDa in wild-type HeLa and A549 cell lysates with no signal observed at this size in S100A4 knockout HeLa cell line ab265709 (knockout cell lysate ab257046) and S100A4 knockout A549 cell line ab261865 (knockout cell lysate ab261674). To generate this image, wild-type and S100A4 knockout HeLa and S100A4 knockout A549 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween^® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged.

Compared with ab197896, ab124805 has higher sensitivity. We recommend ab124805 as an alternative for testing western blot.

We suggest optimizing experimental protocols (increasing lysate amount, using lower dilution or higher sensitivity ECL substrate) to improve results when using ab197896 in western blot.
