Overview

  • Product name

    Mouse IgG1, kappa monoclonal [MOPC-21] - isotype control
    See all Mouse isotype controls

  • Specificity

    MOPC-21 immunoglobulin has unknown specificity and was chosen as an isotype control after screening on a variety of resting, activated, live and fixed rat and human tissues.

  • Tested applications

    Suitable for: IHC-P, IHC-Fr, Flow Cyt, IP, WBmore details

  • Immunogen

    Other Immunogen Type corresponding to Mouse. There is no immunogen for this product because it was not generated through a hybridoma. It was generated by the myeloma of a mouse that was fed mineral oil.

  • General notes

    ab18443 MOPC-21 immunoglobulin is useful as an isotype-matched control in Western blotting, immunoprecipitation, immunohistochemical staining, bioassay and immunofluorescent staining (surface or intracellular) for flow cytometric analysis.

    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 this with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

Question

We purchased your IgG 1 Kappa control antibody (ab18443) about 4 months ago. I was wondering if you could tell me what the lot number would be for that timeframe.

We accidentally tossed the vial and I need it for a report I'm filling out. Thanks for your help!

Answer

Thank you for contacting us.

If you provide me with the institution that placed the order, I will be able to tell you the exact lot number you purchased. However, roughly 4 months ago we were selling lot GR54839-4.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Question

Need IgG isotype control for IHC on paraffin sections. I have 3 mouse monoclonal antibodies which I require isotype controls for - 2 mouse are type IgG1, one is IgG1,kappa. Do I need to match for the kappa as well or can I just use a IgG1? Please can you tell me whether I can just use IgG1 isotype control for all antibodies or does the IgG1, kappa require one of the other isotype controls, such as ab18443 or ab18447?

Answer

Thank you for your enquiry. According to my literature 99% of mouse IgG immunoglobulin molecules have a kappa light chain. This is reflected in the number of IgG, kappa isotype controls in our catalogue. Therefore given that your three mouse antibodies are IgG1; with the light chain unspecified in two of them and one specified as kappa I think that it is safe to assume that you can use a single isotype control relating for all three antibodies relating to heavy chain IgG1 and kappa light chain. For example; ab18443 Mouse IgG1, kappa monoclonal (MOPC-21) - isotype control or ab18447 Mouse IgG1, kappa monoclonal [MG1-45] - Isotype control. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.
