  • 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.

The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Image-iTTM FX Signal Enhancer was used as the primary blocking agent, 5% BSA (in TBS-T) was used for all other blocking steps. DAPI was used to stain the cell nuclei (blue). Alexa Fluor® 594 WGA was used to label plasma membranes (red).

Question

Please see below for the response from the customer;

I finally did the staining with the optimised conditions suggested by Abcam, however I see absolutely no staining at all.

I added 0.2% Tween 20 to my wash and dilution buffers and kept the primary antibody overnight and 4 degrees (1:2000 dilution). I haven't attached any pictures as the background is so faint, that I would have to do a 10 sec exposure to see anything.

If however, Abcam wants a picture, I would be happy to send them some.

Hope this problem can be resolved soon!

Thanks for your help

Question

I have purchased 2 vials of ab18211 recently; in the past this antibody has worked well for WB and IHC. However these recent lot GR68012-1have oddly only worked well for WB but not for IHC; a replacement of a new lot GR71410-1 has again worked as expected for both applications; the same samples, reagents and protocols were used in all cases and only the antibody was different
