Immunoprecipitation - Anti-MEK3 antibody [EPR17345-104] - BSA and Azide free (AB231166)

MEK3 was immunoprecipitated from 1mg of HeLa (Human epithelial cells from cervix adenocarcinoma) whole cell extract with ab195037 at 1/90 dilution. Western blot was performed from the immunoprecipitate using ab195037 at 1/1000 dilution. Anti-Rabbit IgG (HRP), specific to the non-reduced form of IgG, was used as secondary antibody at 1/1500 dilution. Lane 1 : HeLa whole cell extract. Lane 2 : PBS instead of HeLa whole cell extract.

Blocking and dilution buffer and concentration : 5% NFDM/TBST.

Based on the sequence analysis, ab195037 recognizes 3 isoforms of MEK3 ranging from 36kDa to 40KDa. The multi-bands should be MEK3 isoforms.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab195037).

Lanes 1 - 4 : Merged signal (red and green). Green - ab195037 observed at 40 kDa. Red - loading control, ab8245, observed at 37 kDa.

ab195037 was shown to specifically react with MEK3 when MEK3 knockout samples were used. Wild-type and MEK3 knockout samples were subjected to SDS-PAGE. ab195037 and ab8245 (loading control to GAPDH) were both diluted to 1/5000 and 1/10000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
