Serotonin-related Antibodies
Anti-mouse 5-HT1A receptor, rat monoclonal antibody (4A6)
Anti-mouse 5-HT2C receptor, rat monoclonal antibody (6D2)
5-HT1Areceptor and 5-HT2C receptor are G protein-coupled receptors activated by serotonin (5-HT). Both are localized mainly in the central nervous system, and their functions controlling memory, food intake, sleep, pleasure, and anxiety, etc. Anxiolytics and antipsychotics acting on these receptors have been developed, and they are attracting attention of researchers as novel targets for drug discovery.

DNA immunization
What is DNA immunization?
DNA immunization is a technique for generating antibodies against target proteins by using antigen proteins expressed in the animal body with expression vectors containing the target genes.
Features of DNA immunization
- Yields Antibodies specifically recognizing native forms of proteins
- Suitable for preparation of antibodies recognizing membrane proteins that were difficult to prepare by conventional methods
Principles of DNA immunization

-
Localization in the cell body of prefrontal neurons was confirmed.
This localization is consistent with the site highly expressing mRNA for 5-HT1A.
5-HT2C receptor

-
Localization in the cell body of prefrontal neurons was confirmed.
This localization is consistent with the site highly expressing mRNA for 5-HT2C.

Competitor -
A clearer shift was observed for cells expressing 5-HT2C, compared with the competitor.
Usage example - Immunohistochemical staining of the site expressing mRNA for 5-HT1A
![01219_img09.png](images/01219_img09.png)
Positive signals were noted in amygdala (BLA), entorhinal cortex (Ent), interpeduncular nucleus (IP), and dorsal raphe nuclei (DRN).
This localization is consistent with the site highly expressing mRNA for 5-HT1A.
Experimental conditions
Specimens: Various areas of the brain from 10-week-old wild-type mice
Sections: 12 µm-thick frozen sections
Activation condition: Microwave treatment in a citrate buffer (pH 7.0) for 10 minutes
Antibody concentration: 1 µg/mL
Usage example - Immunohistochemical staining of the site expressing mRNA for 5-HT2C receptor
![01219_img10.png](images/01219_img10.png)
Positive signals were noted in nucleus accumbens shell (NAc shell), amygdala (BLA), and dorsal raphe nuclei (DRN).
This localization is consistent with the site highly expressing mRNA for 5-HT2C.

Anti-mouse serotonin transporter, rat monoclonal antibody (R5-3-2)
Serotonin transporter is a 12-transmembrane protein. It incorporates extracellular serotonin in the brain into the presynapse to modulate serotonin levels. With its reported involvement in sleep, fear, and anxiety, serotonin transporter has been investigated as a target of antidepressants.
Features
- Compatible with immunohistochemical staining
- Established by DNA immunization
