Anti-Mu Opioid Receptor 抗体 (ab10275)

Gracias por contactarnos.
Después de consultar este caso con mis compañeros del laboratorio, acerca de los siguientes anticuerpos contra Mu Opioid Receptor validados en tejidos de rata: ab10275, ab17934, ab64746, ab128013 y ab134054, me temo que ninguno de ellos ha demostrado reconocer el epítopo extracelular de la proteína.
Todos ellos se han generado a partir del extremo C terminal de la proteína, por lo que, a pesar de no haberse mapeado el epítopo que reconocen, probablemente detecten el dominio citoplásmico de la misma.
La solución que te propongo es testar uno de los anticuerpos que hay en el catálogo hecho a partir del extremo N terminal de la proteína, y testarlo en rata. Tenemos en abcam un sistema de evaluación de anticuerpos por el cual al testar uno de ellos en una aplicación o especie que no se ha testado, puedes beneficiarte de un descuento en tu próxima compra por valor del anticuerpo, si lo usas en esa especie o aplicación nueva y nos mandas los resultados a la web en forma de Abreview.
Para saber más sobre este sistema: www.abcam.com/abtrial
De las posibles alternativas, ab140911, ab137460 o ab137277 indícame si quieres cuál os interesaría más, para averiguar su homología con la proteína en rata y determinar la posibilidad de reaccionar en esta especie, en caso de que queráis participar en el sistema Abtrial.
Espero haberte ayudado. No dudes en contactarnos de nuevo para cualquier otra consulta.

Thank you for your message and for inform us about this problem.

I am sorry to hear that the free of charge replacement has not improved the results on this occasion. Due to your valuable information this antibody will now be further investigated.

I appreciate the time you have spent on these experiments and would be pleased to arrange a refund or credit note in compensation.

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

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 xxxxx.

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 answer.

I am sorry to confirm that we don't have any different lots in stock at the moment. I would like to reassure you that we monitor feedback closely on a weekly basis and we are not currently concerned about the general quality of this antibody or this batch. Regrettably, I can suggest you have received a bad vial on this occasion.

Therefore, we would be pleased to provide a replacement from the same lot, which will still be covered by our guarantee or even a different antibody. Alternatively, I fully understand your concerns and if you prefer a credit note in this case, I will be pleased to arrange this for you.

I understand that your time is restricted and I appreciate the time you already spent in the laboratory. It would be beneficial, if it is possible for you to try the suggestions we made. We experienced that individual experiments might need different optimisation.

I hope this will be helpful. 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 and contact us. I am sorry to hear you have had difficulty obtaining satisfactory results from this antibody.

The details you have kindly provided will enable us to investigate this case for you and also gives us 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. I would like to reassure you that this antibody is tested and covered by our guarantee for mice and ICC/IF, WB, IHC-Fr, ICC as well as IHC-FoFr applications.

Before deciding how to proceed with this particular case, I would like to offer some suggestions to help optimise the results. I would also appreciate if you can confirm some details of the procedure.

1. Could you please confirm what applications is performed? Was it an IHC-FoFr experiment - perfusion fixed samples?

2. Regrettably we cannot open the send images. Could you kindly provide images in a PDF format please?

3. The described antigen retrieval seems to be long. Because the Mu Opioid Receptor is a membrane protein we would recommend to optimise the antigen retrieval. We would suggest trying no antigen retrieval as well as 2, 5, 10 and 20 minutes.
I can confirm that reviewing the literature in comparable experiments no antigen retrieval was performed (Chuhma N et al. Functional connectome of the striatal medium spiny neuron. J Neurosci 31:1183-92 (2011). IHC-FoFr; Mouse.http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=21273403&dopt=Abstract)

4. Furthermore it might be beneficial to use a less strong detergent then TritonX in this case. TritonX might disrupt the membrane and by doing so prevent the detection of the Mu Opioid Receptor in the membrane. A more gentle detergent is for example Tween. Generally permeabilisation is not always required for mambrane proteins.

5. Could you confirm if and what kind of washing steps were performed in this experiment. Unspecific staining might be due to not suitable washing buffer. Washing steps need to be optimised for every experiment to achieve clear results.

6. We suggest that a no primary control might be beneficial to confirm if the secondary antibody binds unspecific and gives the unspecific staining in the samples.

We are happy to offer this technical support. 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.

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 taking the time to contact us. I am sorry to hear you have had difficulty obtaining satisfactory results from our Anti-Mu Opioid Receptor antibody (ab10275).

I would like to reassure you that this antibody is tested and covered by our 6 month guarantee for applications and species cited on the data sheet. 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.

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 send the questionnaire for IHC. If you were performing WB please let me know so that I can send you the right questionnaire for the application.

It would be very useful for our quality control if you could provide detailed information about the optimisation steps that were performed.

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 questionnaire.

Thanks for your enquiry.

ab10275 is a whole antiserum product and the exact concentration of the anti-Mu opioid receptor in the serum has not been determined. In general, however, specific antibody concentration inproducts of this type is typically 0.5mg/ml or less.

I hope this is helpful. Please contact us again if you have any further questions.
