Western blot - Anti-CD64 antibody [EPR4624] (ab134073)All lanes : Anti-CD64 antibody [EPR4624] (ab134073) at 1/10000 dilution
Lane 1 : Wild-type THP-1 cell lysate
Lane 2 : FCGR1A knockout THP-1 cell lysate

Lane 4 : HEK-293 cell lysate
Lysates/proteins at 20 µg per lane.
Performed under reducing conditions.
Predicted band size: 43 kDa
Observed band size: 45 kDa why is the actual band size different from the predicted?False colour image of Western blot: Anti-CD64 antibody [EPR4624] staining at 1/10000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab134073 was shown to bind specifically to CD64. A band was observed at 45-50/55-80 kDa in wild-type THP-1 cell lysates with no signal observed at this size in FCGR1A knockout cell line ab275843 (knockout cell lysate ab275817). To generate this image, wild-type and FCGR1A knockout THP-1 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. 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.
