      IHC image of Lambda Free Light Chain staining in Human normal tonsil formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with abX1944, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

      For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

    Question

    How were these antibodies tested in Western blot (full protocol)? How should plasma samples be used in Western blot with these antibodies?

    Answer

    Thank you for your call yesterday and for your patience while I have been in touch with the lab regarding your enquiry.

    The protocolused for Western blotting was according to Towbin et al. in: PNAS, September 1, 1979, vol. 76, no. 9, 4350-4354: Electrophoretic Transfer of Proteins from Polyacrylamide Gels to Nitrocellulose Sheets: Procedure and Some Applications. Please find this article attached to this email.


    The lab has not done any testing on these antibodies with plasma samples, so unfortunately we do not have an in-house protocol for this sample type. The positive control used was Bence-Jones protein separated from the urine of a multiple myeloma patient.
    I've looked through some literature and found some resources that might be helpful for running plasma samples on a Western blot-
    http://qjmed.oxfordjournals.org/content/90/3/197.full.pdf
    http://vir.sgmjournals.org/content/69/3/723.full.pdf
    http://www.plosone.org/article/info:doi%2F10.1371%2Fjournal.pone.0008701
    I would recommend treating the plasma samples as you would treat a lysate, by measuring protein concentration and diluting in sample buffer. The optimal protein loading will need to be determined intrinsically for your particular samples, but the above references should give some idea of reasonable protein loading range.
    I hope this information will be useful, but please let me know if you have any further questions or if there is anything else that we can do for you, and I'll be happy to help.
