    • Relevance

      The T7 tag is an 11 amino acid peptide encoded in the leader sequence of T7 bacteriophage gene10. This gene encodes a T7 major capsid protein whose function is not clear. The T7 tag serves as a tag in many expression vectors including the pET system that is based on the very efficient T7 RNA polymerase expression system. Monoclonal antibodies specific for T7 tag are an important tool for studying expression of recombinant T7-tagged proteins.

    Thank you for contacting us.

    Indeed, we can confirm that Agarose-conjugated anti-T7 tag® antibodyab1230 can be used to purify (or pull-down) T7-tagged proteins, as it has been tested and is guaranteed to work in immunoprecipitation (IP).

    For a protocol you can refer to the publication by MacPherson who used thisproduct(see attached, and datasheet). For IP protocols in general our protocols website might be of interest for you: https://www.abcam.com/index.html?pageconfig=popular_protocols

    Thank you for contacting us for technical support with ab1230 on behalf of your customer. Unfortunately it is very hard for me to understand the customer's protocol and results as limited information was provided. Can you please explain what the different lanes are: -what is the positive control? -what is the difference between the two membrane images? (the lanes IP and Total cell lysate don't look the same at all between the two images, I am very confused) -what does "Rx" mean? I would like also to know more protocol information please: -how was the T7 antibody used in WB used: dilution, buffer, incubation time. Is there a positive control for this antibody? -what protease inhibitors were used in the RIPA buffer? -how long was the lysate mixed with the antibody/agarose slurry? -how were the agarose beads uncoupled from the antibody? -what blocking buffer was used: for the beads and the membrane? The more information you can provide the better it will be for me to assist your customer, thank you in advance,
