  • Function

    Receptor for estrogen.
  • Tissue specificity

    Ubiquitously expressed, but is most abundant in placenta. In brain regions, expressed as a 2.8 kb transcript in basal forebrain, frontal cortex, thalamus, hippocampus, caudate and putamen.
  • Sequence similarities

    Belongs to the G-protein coupled receptor 1 family.
  • Cellular localization

    Cell membrane. Endoplasmic reticulum membrane. Golgi apparatus membrane. Protein has been detected in the cell membrane, endoplasmic reticulum and Golgi apparatus. It is currently unclear whether this is a cell surface or intracellular receptor.

  • 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).

  • ICC/IF image of ab39742 stained U87-MG cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab39742 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Thank you for contacting us.
I am sorry to hear you are experiencing difficulties with one of our products. We take product complaints very seriously, and investigate every product that we feel may not be performing correctly.
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.
