  • Function
    This is one of the several different receptors for 5-hydroxytryptamine (serotonin), a biogenic hormone that functions as a neurotransmitter, a hormone, and a mitogen. The activity of this receptor is mediated by G proteins that inhibit adenylate cyclase activity.
  • Sequence similarities
    Belongs to the G-protein coupled receptor 1 family.
  • Post-translational
    Phosphorylated. Desensitization of the receptor may be mediated by its phosphorylation.
  • Cellular localization
    Cell membrane.

  • ab17976 staining 5HT1B in Human colon tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with 10% NBFand blocked with antibody block for 10 minutes; antigen retrieval was by heat mediation in CC1 Mild. Samples were incubated with primary antibody (1/100 in antibody diluent) for 1 hour at 37°C. An undiluted Biotin-conjugated Goat anti-rabbit IgG polyclonal was used as the secondary antibody.

  • ab2607 (4µg/ml) staining 5HT1B in human testis using an automated system (DAKO Autostainer Plus). Using this protocol there is strong staining of membrane compartment of the mature seminiferous tubules and possible interstitial cells.
    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer EDTA pH 9.0 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.

Thank you for your response.

The information provided in the two e-mails is very limited. In the Lab, this antibody has been tested and characterized for Western blot application on human brain tissue lysate and not on SHySy5 cells. You may need to test different dilutions 1/200, 1/100 and/or load more protein.

Unfortunately, It is not clear how much protein was loaded onto the gel. Have you checked the detection system? Is the secondary antibody compatible with the primary antibody?

If you wish to proceed with this enquiry, it would be appreciated to complete the attached Questionnaire.

I am particularly interested in the following information:

- Sample preparation and lysis buffer;

- Total cell lysate or membrane fractions used,

- Loaded amount of protein;

- Blocking conditions

- Host species and specificity of the secondary antibody used,

- Positive control i.e human total brain lysate,

- Order Number and Your PON (order confirmation),

- Date of arrival

I hope this will be useful for you. Should you still have any problem with this antibody after following these suggestions, then please do not hesitate to contact our Technical Department again.

Thanks for your reply.

It is good to know that you have used the Trizol extraction method successfully with other samples. The reason I suggested the negative control sample was because it would, if there is an issue with the antibody specificity here, it would be confirmed with the presence of many non-specific bands in a sample that does not express 5HT1B. However if a blot against this negative control sample is blank or has one of the intense bands is missing as compared to the hamster brain samples, that could confirm there is specific detection of 5HT1B and perhaps further optimization may then be worthwhile.

What do you think?

Thanks for your troubleshooting efforts!

Thanks again for submitting your protocol details as well as the western blotting image.

I just have a couple additional questions:

1) Have you run a negative control sample that you expect would not contain 5HT1B?

2) Have you used these same brain extracts in western blots with any other antibodies?

Thanks for the additional information!
