      Question

      Thanks for your e.mail .. I am asking .. can I used them immunofluorescence (IF) for paraffin embedding section ..

      Do you have protocol start with ..

      Many thanks

      Answer

      Thank you for your reply.

      I have to confirm that we did not test this antibody in IF with paraffin embedded sections.

      This is in theory possible. Although often high background occurs with this method.

      Please follow this link for a protocol:

      https://www.abcam.com/index.html?pageconfig=resource&rid=11459

      I can also recommend this page for in depth information about IHC:

      Question

      Dear Sir/ Madam

      I ordered the following antibodies:

      1) anti-cytokeratin 15 antibodies9(EPR1614Y).(AB52816)



      2) anti-BCRP/ABCG2 antibody (BXP-53).(ab24115)



      I am wondering whether those antibodies can b used in IF , paraffin section / in what concentration .



      many thanks

      Answer

      Thank you for your inquiry.

      I am happy to confirm that both antibodies are tested and guarantee for IHC-P.

      1.) We used ab52816 successfully in a dilution of 1/100 in IHC-P with human squamous cervical carcinoma by Immunohistochemistry, Paraffin embedded tissue.

      2.) ab24115 was used at a dilution od 1/400 in the following publication:

      http://www.ncbi.nlm.nih.gov/pubmed/20472681?dopt=Abstract

      Please not that these dilution factors are only recommended starting points for your own optimization experiments.

      I wish you good luck with your experiments.

      Question

      Dear Abcam,   I purchased a Rabbit monoclonal [EPR1614Y] to cytokeratin 15 (ab52816) four months ago. I aliquoted smaller volumes and stored at -20C as per your data sheet and kept some at 4C. When the aliquot at 4C finished I started using the ones from -20 and since then I am not getting any band of K15. I have used high concentrations as well (1:1000) and use 5% milk. Can you please suggest what may have gone wrong and if possible send me a new aliquot of the antibody?   Many thanks,

      Question

      Dear Abcam,   Thank you for replying.   I do not have the order or product number but I bought it this summer. I use standard western blot procedure using nitrocellulose membrane, I use 5% milk for blocking for 15 mins and also 5% milk for primary and secondary antibody for 1 hr at room temperature. I have always used this protocol and never had any problems including the antibody I am complaining about. I have increased the concentration of primary and secondary to 1:1000 and exposed for 2 mins whereas I normally get a strong band even after 30 sec of exposure. I am using the lysates of immortalised keratinocytes NEB1, KEB11 and HaCaT.   It will be of great help if you can suggest anything or provide a new sample of the antibody.   Many thanks
