  • Function

    Receptor for the neuropeptide nociceptin/orphanin FQ. Has a potential role in modulating a number of brain functions, including instinctive behaviors and emotions. The activity of this receptor is mediated by G proteins which inhibits adenylyl cyclase.
  • Sequence similarities

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

    Cell membrane.

  • Sk-N-SH cells were incubated at 37°C for 24h with vehicle control (0 µM) and 1 µM of kainic acid (ab120100). Decrease expression of nociceptin receptor in SK-N-SH cells correlates with an increase in kainic acid concentration, as described in literature.

    Whole cell lysates were prepared with RIPA buffer (containing protease inhibitors and sodium orthovanadate), 30µg of each were loaded on the gel and the WB was run under reducing conditions. After transfer the membrane was blocked for an hour using 5% BSA before being incubated with ab66219 at 1 µg/ml and ab8227 at 1 µg/ml overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP (ab97051) at 1/10000 dilution and visualised using ECL development solution.

Thank you for your clarification.

I can confirm the concentration of ab66219 (Batch: GR9812) of this ab is 1 mg/ml. The other antibody ab36204 (Lot: GR42382) is not affinity purified but whole antiserum so the IgG is not quantified. However, I can provide a range of the IgG: 10-15 mg/ml.

Isotype controls:

can be searched at this site: https://www.abcam.com/index.html?c=718

ab36204, ab48614, ab66219, ab102998 --> Rabbit IgG - ab37406, ab125938, ab128142

ab83508 --> Mouse IgG1 - ab91353, ab27479, ab81032

Positive control:

ab36204 - CRMP4 - It is mainly expressed in heart and skeletal muscle and also strongly expressed in fetal brain and spinal cord (human, mouse or rat),

ab48614 --Ceruloplasmin - It is expressed by the liver and secreted in plasma,

ab66219 -- Oprl1 - Brain (cortex),

ab83508 -- NG2 - It is detected only in malignant melanoma cells, SK-MEL-28 cells,

ab102998 --B3GNT5- only tested in WB - Widely expressed. It is highly expressed in lung, colon, placenta, testis, pituitary gland and cerebellum, MDA-MB435 cell line

If you need any further assistance in the future, please do not hesitate to contact me.

Thank you for your enquiry and your interest in our products.

This is to confirm that we can only provide the concentration for affinity purified antibodies. For whole serum or supernatant we do not quantify the IgG concentration. I have contacted the lab to get the requested information for you concerning ab66219 (Lot: GR9812).

Would you be so kind to clarify if you wish to look for isotype control or positive control for these primary antibodies listed below?

ab36204 --> Rabbit IgG
ab48614 --> Rabbit IgG
ab66219 --> Rabbit IgG
ab83508 --> Mouse IgG1
ab102998 --> Rabbit IgG

I look forward to hearing from you soon. As soon as I have further information on the concentration (ab66219), I will contact you again.

Thank you again for contacting us, and I apologize for the extended delay regarding these peptides.

The blocking peptide for ab66219 is now available in our catalog as ab129205-


I am still working on having the blocking peptides for ab77384, ab77384, and ab65700 added to the catalog, and I hopeto have this done shortly.

As I mentioned before, ab66219 has not been tested in IHC-P but it may be suitable for this application. If you are interested in trying this antibody in IHC-P, we do have a testing program available. In this program, you would receive a free primary antibody on a future purchase after purchasing and testing ab66219 then submitting an Abreview with your data. If you are interested in this program, I would be happy to send more information.

I will get back in touch with you once I have more information about the peptides for the other antibodies. Please let me know if you have any questions or if there is anything else that we can do for you.

Thank you for contacting us last week and for your patience while I have been working onadding these blocking peptides to our catalog. I apologize for the extended delay getting back to you.

Thesepeptides will be added to our catalog shortly, and I will then email you thecatalog numbers so you will be able to order them. Regarding ab66219, we have not tested it in IHC-P but it iscertainly possible that it will work. The antigen retrieval method and dilution factor may need to be optimized, but if you have any trouble please let me know and I'll be happy to help you optimize the conditions.

I will be in touch soon. Please let me know if you haveany questions in the meantime, and I'll be happy to help.
