ターゲット情報

  • 機能
    Photoreceptor required for image-forming vision at low light intensity. Required for photoreceptor cell viability after birth. Light-induced isomerization of 11-cis to all-trans retinal triggers a conformational change leading to G-protein activation and release of all-trans retinal.
  • 組織特異性
    Rod shaped photoreceptor cells which mediates vision in dim light.
  • 関連疾患
    Retinitis pigmentosa 4
    Night blindness, congenital stationary, autosomal dominant 1
  • 配列類似性
    Belongs to the G-protein coupled receptor 1 family. Opsin subfamily.
  • 翻訳後修飾
    Phosphorylated on some or all of the serine and threonine residues present in the C-terminal region.
    Contains one covalently linked retinal chromophore.
  • 細胞内局在
    Membrane. Synthesized in the inner segment (IS) of rod photoreceptor cells before vectorial transport to the rod outer segment (OS) photosensory cilia.

    Overlay histogram showing Y79 cells stained with ab98887 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab98887, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in Y79 cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

Question

I need help again, I send you the file of my WB with the Rhodopsin ab98887 you report the ab is around 39kDa if you see the image of the wb the band maybe I think it is less than 37kDa, what do you think? And I am very surprise how the ab are up the 50 to 250kDa? Is not very clean ab? What are your suggestions? This is what I did: SDS 10%, transfer to Nitrocellulose, Blocking for 1hr at RT with 5%Milk on TBSt, the primary ab Rhodopsin ab98887 at 1:1000 on 1% Milk overnight, 4 washes with TBSTt every 5 min, incubate with secondary ab98693 at 1:2000 on 1% Milk for 1hr, 6washes of 5min with TBST, and I did ECL the exposition time was very fast like 10 sec, more than that is get it so dark.

Answer

Thank you for contacting Abcam and thank you for sending the details of your protocol as well as the image. These have been very helpful.

After reviewing your protocol, I would like to suggest a few tips which may help reduce the upper dark areas and increase the band quality for Rhodopsin.
First I would recommend changing your blocking procedures. It may be best for this product if your initial blocking and primary antibody incubation are performed using 3% BSA in TBST. This should be followed by use of a casein based commercial block for incubating your secondary antibody. We have seen that this may dramatically reduce background in western blot. We do carry this type of casein based blocking reagent, ab64234 (https://www.abcam.com/Background-Reducing-Buffer-ab64234-support.html).

Second, you may wish to reduce the concentration of secondary antibody that you use. This product has a large range 1:2000-1:20,000 against which it has been used effectively.

Finally I would suggest increasing the concentration of detergent in your TBST, if you currently use 0.1% Tween20 use 0.25% Tween20 instead.

Question

Hi, I'll try again all this changes to see if I can improve the quality of the band of Rhodopsin, but what about the size of the band? Is the correct size? And Can you please send me if you have reviews using this ab, Do you have publications with this ab? Thanks,

Read More
Answer

Thank you for contacting us.

The band size seems to be correct. This product has a predicted weight of 39kDa although you band seems a bit smaller this is common when using in real world settings as compared to predictions. Post translational modifications are a common cause of this as well as the inherent inaccuracies of protein marker standards. These are often labeled as 'apparent' size because they may be off by 3-30kDa.
In regards to further data and publications, to our knowledge this product has not been published with. We always include any information that we may have regarding publications, reviews or any information that we about the antibody on our website.


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