Anti-mono and dimethyl Arginine 抗体 [7E6] (ab412)

Thank you for contacting us.

These antibodies are raised against targets that are not species specific. The antibodies would detect the proteins irrespective of species so the Abtrial discount will not be valid.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for confirming these details and for your cooperation. The details provided enable us to closely monitor the quality of our products.

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 with the order number #######.

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.

Thank you for your message and for providing this further information.

I am sorry to hear the suggestions made have not improved the results on this occasion. I appreciate the time you have spent on these experiments and would be pleased to arrange a free of charge replacement or credit note in compensation.

I look forward to hearing from you with details of how you would like to proceed.

Thank you for taking the time to complete our questionnaire. The details you have kindly provided will enable us to investigate this case for you and this is also helpful in our records for monitoring of quality.

Reviewing this case, I would appreciate if you can confirm some further details:

1. Could you confirm if reducing and denaturing conditions have been tried? We recommend to use antibodies in reducing and denaturing conditions in WB unless it recommends to use non denaturing and reducing conditions on the datasheet. This will ensure that the proteins are in the correct conformation to run at the correct molecular weight and be detected by the antibody.

2. Could you confirm what size are the 3 bands in the blot in the eluted samples? And what size bands were you expecting?

3. How was the sample eluted from the IP column? Which buffer was used?

4. Which lanes are the whole cell extract in, is this lane 1 and 2 (input A and B?).

5, Has the transfer to the membrane and quality of the sample been assessed with a loading control in the whole cell extracts? Transfer to the membrane may be different from the eluted samples if they are in different buffers etc).

I hope this information is helpful, thank you for your cooperation. Should the suggestions not improve the results, please do not hesitate to contact me again with the further requested details.

Thank you for your recent telephone call and for taking the time to contact us. I am sorry to hear you have had difficulty obtaining satisfactory results from this antibody.

I would like to reassure you that this antibody is tested and covered by our 6 month guarantee for WB. In the event that a product is not functioning in the tested applications and species cited on the product data sheet (and the problem has been reported within 6 months of purchase), we will be pleased to provide a credit note, free of charge replacement or refund.

As requested, I have obtained some more information regaring Western blot protocols using ab412 mono and dimethyl Arginine antibody [7E6] . I hope the following publications in which the antibody has been used in WB will be helpful:

Blifernez O et al. Protein arginine methylation modulates light-harvesting antenna translation in Chlamydomonas reinhardtii. Plant J 65:119-30 (2011).

McBride AE et al. Specific sequences within arginine-glycine-rich domains affect mRNA-binding protein function. Nucleic Acids Res 37:4322-30 (2009).

Gupta P et al. PKCepsilon stimulated arginine methylation of RIP140 for its nuclear-cytoplasmic export in adipocyte differentiation. PLoS ONE 3:e2658 (2008).

As discussed on the telephone, I would like to investigate this particular case further for you, and also obtain more information for our quality monitoring records. In order to proceed with this, I have enclosed a technical questionnaire below. I would appreciate if you could complete this. It will help you put the information we require together very easily.

I would appreciate if you could also provide an image which would help us to assess the results.

Thank you for your time and cooperation. We look forward to receiving the completed questionaire.

Please let me know how you would like to continue.
I look forward to your reply.

Thank you for contacting Abcam.
The antibody is covered under our Abpromise for six months and is guaranteed to work in western blot on a variety of samples . If we cannot resolve the issue you are having with the antibody then I would be happy to either send a replacement antibody or to process a refund.
To be able to help further in this matter, could you please provide me some more information about the nature of the problem and also some protocol information?
1 - What sample type are you using?
2 - Are you seeing any bands, no bands etc?
3 - How much sample are you loading?
4 - What type of blocking agent are you using?
5 - What primary antibody concentrations have you tried and how long do you incubate for?
We do take all complaints on products seriously and we do our best to solve these problems.
