General notes
The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.
One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.

Western blot - Anti-CD74 antibody [LN2] (ab265584)All lanes : Anti-CD74 antibody [LN2] (ab9514) at 5 µg/ml
Lane 1 : Wild-type Raji cell lysate
Lane 2 : CD74 knockout Raji cell lysate
Lane 3 : Jurkat cell lysate
Lane 4 : HepG2 cell lysate
Lysates/proteins at 30 µg per lane.
Performed under reducing conditions.
Predicted band size: 34 kDa
Observed band size: 35 kDa why is the actual band size different from the predicted?This data was developed using the same antibody clone in a different buffer formulation (ab9514).
Lanes 1 - 4: Merged signal (red and green). Green - ab9514 observed at 35 kDa. Red - loading control, ab52866 (Rabbit anti-alpha Tubulin antibody [EP1332Y]) observed at 55 kDa.
ab9514 was shown to react with CD74 in western blot. The band observed in CD74 knockout cell line ab273378 (knockout lysate ab275529) below 35 kDa is likely to represent a truncated form. This has not been investigated further. Membranes were blocked in fluorescent western blot (TBS-based) blocking solution before incubation with ab9514 and ab52866 (Rabbit anti-alpha Tubulin antibody [EP1332Y]) overnight at 4 °C at 5 µg/ml and a 1 in 20000 dilution respectively. Blots were incubated with Goat anti-Mouse IgG H&L (IRDye® 800CW) preabsorbed (ab216772) and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preabsorbed (ab216777) secondary antibodies at 1 in 20000 dilution for 1 h at room temperature before imaging.
