Question

The customer would like to try positive control.
They will try ab109255 IRF7 antibody, on Jurkat cell lysate, but they do not have NIH3T3 for ab32520 STAT6 antibody. Could you please suggest other human cell lysate as the positive control for ab32520 STAT6 antibody?

Abcam community

Verified customer

Asked on Mar 12 2013

Answer

The Jurkat lysate will serve as a positive control for STAT6, in addition to IRF7. Although ab32520 has not been tested on Jurkat, other STAT6 antibodies have been, and the results demonstrate that Jurkat expresses this protein. For an example western blot of Jurkat stained for STAT6, please see the datasheet for ab125303: https://www.abcam.com/stat6-antibody-ab125303.html.

In answer to your questions:

1. Already done. no effect

2. Is not possible, blocking agents are included in the detection kit provided by Ventana/Roche. There are no options to separate blocking agents.

3. Is not possible to incubate at 4°C with a Ventana Benchmarck system.

4. Secundairy Ab in detection kit is working with other primary antibodies.

Our collaborators from Nijmegen used the same antibody in the same setting with good results. Therefore we would like to give it another try with the same antibody. Could you please send us a new vial with anti-STAT6? We will try again on the same and some new tissues. I will keep you informed how we will get on with it.

Answer

Thank you for taking the time to complete our questionnaire and contact us. The details you have kindly provided will provide us with vital information for our monitoring of product quality.

I appreciate the time you have spent in the laboratory and understand your concerns. It is regrettable the results have not been successful. Reviewing the details.

I can recommend you may like to consider trying the following options:

1. The time for antigen retrieval can sometimes require some optimization. For example I can recommend to try , 5, 10 and 20 minutes if this has not already been done.

2. We recommend not to mix blocking agents in one experiment. I can recommend to try serum only (no casein).

3. I can suggest to try overnight incubation at 4oC. This sometimes provides more specific and efficient staining.

4. Could you confirm if the current vial of secondary antibody is working well with other primary antibodies?

Alternatively, or if these tips do not work, I am pleased to offer you a free of charge replacement or credit note in compensation.

Thank you for your cooperation. I look forward to hearing from you with details of how you would like to proceed.

Question

Dear Sir, Dear Madam,

Concerns: Product ab32520 LotNo GR17723

On the 10th of August I received from you the antibody with product number ab32520 (Rabbit monoclonal [YE361] to STAT6). We have tested this antibody using immunohistochemistry on prostate carcinoma, human skin, breast carcinoma and non-hodgkin's lymphoma. Unfortunately none of these tissues show any signal, not even background staining. Immunohistochemistry was performed with a Ventana IHC system by Roche using both TRIS and Citrate buffers and different antigen retrieval times. Concentrations used ranged from 1:25 till 1:500.

Alongside your antibody we used other anti-STAT antibodies that did show a signal. The antibody was handled as advised by you upon arrival (aliquoted and frozen at -20oC). It appears that this antibody is not functioning properly. Could you please give us some advise how to test the antibody? Or could you verify if something is wrong with this lot? Thank you for your help in advance.

Yours sincerely,

Asked on Sep 26 2006

Answer

Thank you for contacting us regarding ab32520. I'm sorry to hear you are experiencing problems with this antibody which has been tested in IHC-P and should work in lung tissue of mouse and human. Could you please confirm the species of your samples? If it is not from the above species then the problem may be that the antibody does not recognise the species you are working with. I would like to recommend trying the following steps to improve your signal: 1)reduce the fixation time as overfixed tissue shows modified antigens which cannot be recognized by the antibody 2) vary the antigen retrieval time as too little or too much can also modify the antigen such that it is not optimally recognized by the antibody 3) use PBS containing 0.3% triton to dilute the blocking buffer and antibodies in 4) check that the tissue is washed in PBS a lot before adding the antibody, as the remaining fixative can fix the antibody and prevent its binding 5) check that the secondary antibody works with other primary antibodies, as well as your ABC kit. As you have tried this staining once I would first recommend to run this again as it may be that there was a problem in one of the steps in your first attempt. I can also please make sure that endogenous peroxidases are blocked? I hope this information helps, please do not hesitate to contact us if you need any more advice or information or still experience a problem following the modifications advised. I can offer you a refund or replacement vial if the antibody was purchased in the last 90 days,
