The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-Fr Use at an assay dependent concentration.

IHC-P Use at an assay dependent concentration.
Flow Cyt 1/2000.


  • ICC/IF image of ab6046 in HeLa cells. The cells were 100% methanol fixed (5 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab6046, 2µg/ml) overnight at +4°C. The secondary antibody ab150079 (shown in red) was used at 1µg/ml for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

    The negative control (inset) is a secondary-only assay to demonstrate low non-specific binding of the secondary antibody.

Thank you for your email. I am sorry to hear that you have been experiencing problems with this antibody.

I have read the details you have kindly provided and have following further questions for better understanding of the problem;

- Have you used correct filters? The ab150079 absorption maxima is 650 nm while for FITC (ab98692) it is 495.
- Were the cells permeabilized?
- Is the sequence of insert protein is interpreted. It may well be that the insert sequence is missing which ab128251 binds.
The antibodies ab128251 and a84815 are raised against different part of the immunogen.
- Have you tried optimizing the results by incubating the antibody overnight or by increasing the concentration?

In order for checking the quality of ab150079 you may put a small drop of ab on slide and then seeing it under microscope. If it emits red colour then conjugate is fine and the problem may be with other steps. If it's not then problem is with secondary antibody.

It will be very helpful if you could provide the protcol followed step by step.

Please note that flow cytometry is not a tested application for ab128251 so the Abreview guarantee will not be valid. However if this antibody fails in ELISA, WB and ICC/IF then guarantee will apply as normal product.

Thank you very much for your cooperation. I will look forward to hearing from you soon.
