    ICC/IF image of ab18211 stained human HeLa cells. The cells were methanol fixed (5 min) and incubated with the antibody (ab18211, 1µg/ml) for 1h at room temperature. 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).

    ab18211 at 1/300 staining adult rat brain (perfusion fixed) tissue sections by IHC-Fr. Adult rat was perfused intracardially with paraformaldehyde 4% in PB 0.2M. The brain was post-fixed in the same fixative for 24 hours. Sections were cryoprotected with sucrose 20% and later frozen in OCT. Sections were incubated in free floating for 12h with the primary antibody (1/300) and later revealed with secondary antibody conjugated with Alexa Fluor ® 488 (1/2000).

    The staining obtained is restricted to the cytoplasm and consists of a small and thin punctate staining. The picture shows the staining obtained at the level of the spinal cord using the X20 objective and zooming on two particular neurons.

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
