Mouse lung normal tissue lysate - total protein (ab29297)

Overview

  • Product name
    Mouse lung normal tissue lysate - total protein
    See all Lung lysates
  • Description
    Mouse lung total protein lysate
  • General notes


    Protein is isolated from whole tissue homogenates using a proprietary technique. The tissue was frozen in liquid nitrogen immediately after excision and then stored at -70ºC. Quality control: 1. The isolated protein pattern on SDS-PAGE gel is visualized by coomassie blue staining. The pattern is consistent with each lot. 2. The isolated protein is Western Blot analyzed by either a GAPDH or beta-actin antibody. The expression level is consistent with each lot. Ethics: Human tissue samples are collected with the informed consent of the donors & relatives and are excised by licensed medical doctors. Tumor tissue samples are diagnosed and identified by at least two different evaluators. If you have more questions then please feel free to contact us. Donor information can be supplied on request.

Answer

Thanks for your reply.

ab81673 has been tested for use in WB and IP so the experiment you propose should be fine. An alternative is to use one VAP1 antibody for IP and second VAP1 antibody for WB.

I am sorry this product did not perform as stated on the datasheet and for the inconvenience this has caused. As requested, I have issued a free of charge replacement for one vial of ab48281.

To check the status of the order please contact our Customer Service team and reference this number.

Please note that this free of charge replacement vial is also covered by our Abpromise guarantee. Should you still be experiencing difficulties, or if you have any further questions, please do not hesitate to let us know.

I wish you the best of luck with your research.

Question


I attached our previous run of the lysate you sent us next to one we had. The one we’ve been using still produces a 75 kDa band, rather than the 85-100 kDa band that your website lists as VAP-1. As you can see, the lysate you sent us produces a much lower band under the same conditions.

It’s possible that this 75 kDa band is VAP-1, and for whatever reason we’re getting a slightly lower band than we should. We would believe this is the case if we could corroborate it with a positive control, but the lysate you sent us didn’t work as planned, either with the original antibody we bought or with the new antibody you gave us. It produced a much lower, 37 kDa or so band.

Abcam has sent us a free antibody and a free lysate, which we really appreciate, but they just have not worked in our hands the way your website guarantees they should. I’m not sure if this is a problem with the antibody itself, the lysate we had, or with our conditions, but it isn’t working the way we need it to. We think the lysate you gave us may be the issue because its results are very different from anything else we've run with either antibody. We’re currently using reducing conditions, so if there are other suggestions you may have that might help, that would be great.

The other antibody we have for VAP-1 is ab81673, which we haven’t used in western blotting because it isn’t guaranteed for western blot. This one does work fine for us for other uses.

We’d really like a different lysate to use as a positive control, because our other loading controls don’t produce a band in your recommended range.

Answer

Thanks for your email.

Since you have ab81673 I would recommend using it in a western blot with the 2 lysates you have been testing. It is quite likely this antibody will work in western blotting as it has already been shown to work in a diverse application range.

Thanks for all your troubleshooting efforts. I look forward to hearing how this next western blot goes.

Answer

Thanks for your email.

The data you are seeing do appear unexpected.

Reducing conditions are used during western blotting.

Before I believe a loading control western blot was producing expected banding pattern so I don't think this is an issue with the lysates. More likely it appears to be an issue with the antibody.

Have you used any other anti-VAP-1/AOC3 antibodies to test for reactivity via western blotting?
