  • Anti-G-protein coupled receptor 30 antibody (ab39742) at 1 µg/ml + Human brain normal tissue lysate - membrane extract (ab29456) at 10 µg

    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 42 kDa
    Observed band size: 55 kDa
    why is the actual band size different from the predicted?

    GPR30 contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted.
  • ab39742 staining cultured rat primary astrocytes by ICC/IF. The cultured cells were fixed with 4% paraformaldehyde for 5 minutes and blocked with 10% donkey serum in 0.1% PBS-0.3% TritonX for 30 minutes at 24°C. The cultured cells were then stained with ab39742 at 1/500 in 0.3% TritonX with 0.1% PBS and 10% donkey serum for 4h at 24°C. An Alexa Fluro 488 donkey anti-rabbit polyclonal antibody at 1/1000 was used as the secondary antibody. Nuclei were stained with 1.43µM Hoechst and can be observed in blue. In red astrocytes can be observed (monoclonal anti GFAP).

In order to understand the problems encountered more fully and be able to offer any tips which may improve the results observed so far, would you mind answering the following questions:
1. Sample preparation: Lysis buffer: Protease inhibitors: Reducing agent: Heated prior to loading on gel? Temperature/time:
2. Was a loading control used?
3. Which secondary antibody is being used? Has this been used with any other primary antibody before? What have been the results of this?
4. Order number (or if you do not have access to this the approximate delivery date and the delivery address used).
This information will also allow us to investigate this case internally and initiate additional testing where necessary.
If the product was purchased in the last six months and is being used according to our Abpromise, we would be happy to replace or refund the antibody.
I look forward to receiving your reply.

Thank you for contacting us. Can you tell me how your oocyte samples were fixed and embedded? Were you using fluorescent or colorimetric detection? Fluorescent signal can easily fade after storage for a few days, whereas colorimetric signal will be stable for months to years at room temperature, provided that the samples are properly fixed and embedded. How were you storing your samples? Were they mounted to a slide and coverslipped, or were they in solution? The signal should be more stable when the samples are mounted. I hope this helps, please let me know if you need any additional information or assistance.

Gracias por contactarnos.

He llevado a cabo una búsqueda en nuestro catálogo de anticuerpos contra los receptores indicados:

-Para MAS, tenemos dos opciones, pero lamentablemente ninguna de ellas se ha validado mediante IP, pero si en WB. Si queréis echar un vistazo a sus datasheets adjunto el enlace a ellas:

-Contra GPER, también hay dos anticuerpos disponibles, aunque me temo que tampoco se han usado en IP. Uno de ellos sin embargo se ha validado en WB:

-Contra ER alpha Receptor, hay varios anticuerpos validados mediante IP con células humanas, podéis echar un vistazo a las distintas alternativas en el siguiente enlace:

-Por último, para Estrogen Receptor beta, también hay dos alternativas validadas en IP con células humanas:

Siento que para los dos primeros receptores no haya una alternativa adecuada, sin embargo si queréis, podéis participar en nuestro sistema de evaluación de anticuerpos Abreview.

En Abcam ofrecemos un servicio de evaluación de anticuerpos, llamado Abreview, por el cual podemos ofrecerte un descuento (por valor de un anticuerpo primario / proteína) para una futura compra si adquieres el producto y lo testas en una aplicación o en una especie no testada hasta ahora (como IP), y publicas los resultados en nuestra website, en forma de Abreview, independientemente de que éstos sean positivos o negativos.

Si estás interesado en la oferta, házmelo saber antes de comprar los anticuerpos, para que te envie el código canjeable por un anticuerpo gratuito en la futura compra.

Thank you for getting back to me regarding this case.

I have gone ahead and arranged for ab52650 Anti-PTP1B antibody [EP1837Y]to be shipped to you using the same purchasing route as before. We currently do not have local stock and our overseas stock will only reach you some time next week.Please also inform yourlocal sub-dealer (宮崎化学品株式会社) that you are expecting this free of charge product from us so that they too will be looking out for it. (Order # 1113473)

If there is anything else that I can help you with please do not hesitate to contact me.

Have a nice day!

Thank you for your feedback.

I am sorry to hear that the different lot replacement vial also did not work as you hoped. Should you be interested in a different target primary antibody from our catalogue, I will be more than happy to offer you a free primary antibody of your choice. Simply inform me the catalogue number and I will arrange for the product to be shipped to you.

I hope this one incident will not hinderyou from considering us again as your source of antibodies and reagents in the future.

Thank you and good luck in your research.

Thank you for contacting us.  We currently have three antibodies that recognize GPCR GPR30: ab39742 - rabbit polyclonal; reacts with: human, mouse, and rat; tested for IHC-Fr and WB ab118512 - goat polyclonal; reacts with human and predicted to react with mouse and rat; tested for IHC-P ab98075 - rabbit polyclonal; reacts with human; tested for Flow Cyt, ICC/IF, and IHC-P. I hope this helps, please let me know if you need any additional information.

Thank you for your enquiry. I am sorry to hear that you are experiencing difficulties with this product ab39742 in western blot. Since you mentioned that you are getting expected results in immunohistochemistry but not in western blot (WB), the problem may be with the WB application. If you would instantly like a replacement with a different lot or product, I will be more than happy to arrange that for you. Please provide the name of your sub-dealer and sales person so that I can trace your original order number. If you would like some troubleshooting tips, here are some suggestions. 1) I can see from the image that the whole blot is rather dark and have streak of bands. Here at Abcam , we normally use 5% BSA to block membranes and do get cleaner images. If you have BSA in your lab, you may want to try it out. Also, performing a no-primary antibody experiment will be helpful in determining if your secondary antibody is causing the non-specific bands or not. 2) Although we normally recommend loading about 20-40ug of protein, this sometimes is more than enough and cases multiple bands and /or high background. If possible, could you try 10ug sample?  3) Lastly, boiling of sample is done at 98°C for 10 min to ensure that the protein is in the correct conformation to run at the correct molecular weight and be detected by the antibody. I hope the tips may be helpful. If not, then please do not hesitate to contact me. Also, please advise me on how you would like to proceed with your enquiry, so that I can immediately arrange for a replacement to you. I look forward to hearing from you again in order to resolve the matter.

Thank you for bringing this to our attention.

We have received several complaints over the past two years but without consistent observations, and none similar to yours. Our own data has the protein appearing at about 52 kDa. The assumption has been that glycosylations slow down migration in the gel. The predicted molecular weight of 42 kDa is based on the primary amino acid sequence, before modification post-translation.

So it is difficult to confidently say that the bands near 45 kDa in your blots are in fact GPR30 or are instead another protein that the antibody cross-reacts with. For the rat brain samples, a smear rather than two distinct bands is more expected, as a consequence of different amounts of glycosylation. We have not seen a band at 70 kDa before.

Can you please tell me how the samples were prepared before loading in to the gel? Also, how much protein was loaded per lane? Have you staining blots of these samples for any other proteins, and if so, were the results as expected?

Can you please send the order number or approximate date of the order? If I cannot make a suggestion, we have another lot available which may be worth a try.
