  • IHC image of Histone H1.0 staining in human colon formalin fixed paraffin embedded tissue section*. The section was pre-treated using pressure cooker heat mediated antigen retrieval with sodium citrate buffer (pH6) for 30mins. The section was incubated with ab11080, 7.5µg/ml overnight at +4°C. An HRP-conjugated secondary (ab97240, 1/2000 dilution) was used for 1hr at room temperature. The section was counterstained with haematoxylin and mounted with DPX.

    The inset negative control image is secondary-only at 1/500 dilution.

Western blot
This antibody is super specific! It does not react with mouse IgG2a or human IgG, or any IgG light chain I tested so far.

I use it because I work with mouse tumor lysate in western blot. All tumor lysate contains blood, so IgG is always in the lysates. When my protein of interest is at the same molecular weight of IgG light chain, I use this antibody.

The purpose of western blot I show here is to verify if this antibody reacts with light chain of mouse IgG1 specifically, so there is no primary antibody used.

The antibody is quite clean. The image I show is over-exposed with some background in order to confirm there is absolutely no IgG light chain signal.

Thank you for your interest in our secondary antibodies. I will answer your questions as best I can now but cross-reactivity of the mouse anti-human IgG isotype antibodies will require data from tests which I do not have at hand. I will forward these t...

Thank you for your enquiry.

I can confirm that ab43ERCC1 antibody [3H11] is a mouse monoclonal,IgG2a isotype.

The ab97240 secondary antibody detects mouse IgG1 isotype, so it would not be suitable for use with ab43. You will need ...

Thank you very much for your email. I have compiled here below a list of antibodies which I think could correspond to your needs. There are three different IgG1 and three different IgG2a antibodies which have been tested against other isotypes. ...
