  • ICC/IF image of ab108346 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab108346, 1/100) overnight at +4°C. The secondary antibody (green) was ab96899, a goat anti-rabbit DyLight® 488 (IgG; H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM

  • Overlay histogram showing HeLa cells stained with ab108346 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab108346, 1/1000 dilution) for 30 min at 22°C. The secondary antibody used was a goat anti-rabbit Alexa Fluor® 488 (IgG; H+L) (ab150077) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.

    Perform heat mediated antigen retrieval before commencing with IHC staining protocol.

I have been a loyal customer of Abcam for quite some time, having purchased >50 antibodies from the company over the past five years alone. Typically, I have found Abcam antibodies to be of supreme quality, and they have tended to perform very well in their recommended applications when I follow the guidelines outlined on their spec sheets.
It is for this reason that I was surprised and disappointed by the poor performance of three different antibodies that I have purchased from Abcam over the past year:
ab108346 (BCL2L12)
ab115467 (Bcl-G)
ab94429 (BIRC6)
Each of these three antibodies are recommended for use in IHC from paraffin sections for detection of the corresponding human proteins. However, despite the fact that I adhered strictly to the guidelines and dilutions outlined on each of their spec sheets, I failed to detect appropriate signal from any of these three antibodies from paraffin-embedded human tumor samples that I know express these three proteins based on independent validation methods. In these same experiments, I did observe positive signal from other antibodies, suggesting that my secondary antibodies and other reagents, as well as antigen retrieval, are not to blame. Moreover, I have since purchased IHC antibodies against several of these proteins from other vendors and have obtained more satisfactory staining with their reagents on these same tumor specimens, again verifying their expression in these samples. Together, these facts lead me to conclude that the problem arose with these three primary antibodies themselves.
Again, I have been a loyal customer of Abcam for many years, but these experiences have left me disappointed and I therefore wished to bring them to your attention as I contemplate where I will purchase my antibodies from in the future.

Thank you for contacting Abcam.

I am sorry that you experienced difficulties with several of our antibodies in your experiments. I have reviewed the product datasheets and both ab108346 and ab115467 are validated and guaranteed to work in IHC-P with human tissue, therefore I am happy to offer a replacement or refund for these products. It appears that ab94429 has only been validated for WB. Since we have not tested the product in IHC-P we are not able to guarantee that it will work in this application.

In order to process your request, would you please provide the following information:
- order number or PO
- brief summary of your protocol (we will further investigate the problem you have reported and this will help us to do so)
- your preference of receiving a replacement (and which products you would like to receive) or a refund

I look forward to your reply so that I may assist you further and I apologize for the inconvenience this has caused. Please do not hesitate to contact us if you have any additional questions.
