Blocking and diluting buffer and concentration : ½ volume of Odyssey Blocking Buffer (TBS)+ ½ volume of 0.1% TBSLysates at 20 µg per lane. Performed under reducing conditions. False colour image of Western blot : Anti-HLA E antibody [EPR25300-104] (ab300553) staining at 1/1000 dilution, shown in green; Mouse anti-Tubulin antibody [DM1A] (ab7291) loading control staining at 1/20000 dilution, shown in red.In Western blot, ab300553 was shown to bind specifically to HLA E. A band was observed at 40kDa in wild-type A549 cell lysates with no signal observed at this size in HLA E knockout cell line ab267080 (knockout cell lysate ab258452). To generate this image, wild-type and HLA Eknockout A549 cell lysates were analyzed. First, samples were run on an SDS-PAGE gel then transferred onto an immobilon-FL PVDF membrane. Membranes were blocked in in Intercept® (TBS) Blocking Buffer diluted with an equal volume of 0.1% TBS 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. Secondary antibodies used were Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) at 1/20000 dilution.
