The ImmunoStar serotonin antiserum was quality control tested using standard immunohistochemical methods. The antiserum demonstrates strongly positive labeling of rat hypothalamus and spinal cord using indirect immunofluorescent and biotin/avidin-HRP techniques. Recommended primary dilution is 1/5000 - 1/10,000 in PBS/0.3% Triton X-100 - Bn/Av-HRP Technique.
Staining is completely eliminated by pretreatment of the diluted antibody with 100 µg of serotonin/BSA conjugate.

This serotonin antiserum is great
Brain tissue sections were rinsed three times in 0.1 M PBS and then incubated with ImmunoStar 5-HT (Serotonin) Goat Antibody (Item # 20079) diluted 1:5000 overnight at 4C. After rinsing with 0.1 M PBS, the sections were incubated an anti-rabbit secondary antiserum for 2 h. This secondary antiserum has been shown to have minimal cross-reactivity to other relevant species. Sections were cover slipped and examined under a confocal microscope system.
Brain tissue sections had the clear 5-HT immunolabeling in serotonin neuron dendrites while the negative control sections (without 5-HT (Serotonin) Goat Antibody treatment) showed just background fluorescence. This serotonin antiserum is great and it did work beautifully in our set-up.

Very Good Antibody - Recommended
This antibody produces a robust signal with minimal background and clear staining of somata and processes. Our neuroanatomy results with ImmunoStar goat anti-serotonin are identical to those we found using another well known antibody from another manufacturer made in rabbit.
Brain tissue is from animals transcardially perfused with Ringer's solution followed by 4% paraformaldehyde in phosphate buffer (0.1M, pH 7.2). Tissue is cryosectioned at 25 microns.
Our procedure is as follows:
1. Rehydrate tissue in PBS (0.1M phosphate buffer saline, pH 7.2) for 10 minutes twice.
2. Immerse tissue in PBST+DS-5% (PBS with 5% donkey serum and 0.3% Triton-X) for 1 hour.
3. Apply goat 5-HT antiserum diluted 1:1000 in PBST+DS-5% and incubate at room temperature overnight.
4. Wash tissue with PBS+DS-0.5% (0.5% donkey serum solution, no Triton-X) for 10 minutes five times.
5. Apply secondary antiserum diluted 1:400 in PBST+DS-5% and incubate at room temperature for 2 hours.
6. Wash with PBS for 10 minutes six times.
7. Mount slides and view.

Very Reliable Antibody
Below is my protocol. I also have a picture of the brain of a cockroach labeled with this antibody.
Overnight (O/N) at 4oC in 4% paraformaldehyde in 0.01 Phosphate Buffered Saline (PBS).
Wash tissue 3x 5 min in PBS. Embed in 5% agarose and section at 50-150um.
Wash 4x 15 min in PBS with .5% Triton X-100 (PBST). Block 1 hr in PBST with 2% Bovine Serum Albumin (BSA). O/N at room temperature (RT) in 1:1000 goat anti-5HT in PBST with 5mM sodium azide (PBSAT) with 2% BSA and 1% Triton X-100.
Wash 4x 30 min PBST. Block 1hr 2% BSA in PBST. O/N at RT in 1:1000 donkey anti-goat Alexa 546 (2% BSA in PBSAT).
Wash 2x 15min PBST. Wash 2x 15min PBS. Wash 1x 15min in 60% glycerol. Mount in 80% glycerol.

Great staining with Serotonin antibody
The 5HT antibody always yielded great staining and we were very pleased with it. Indeed, we utilized this antibody for studies of dorsal raphe 5HT neurons as reported in our recent publication in Cell Metabolism (Lam, Leinnintger et al 2011, Cell Metab 13(5): 584-91).

Q & A Wall
The datasheet on your web site said ”Serotonin coupled to bovine serum albumin (BSA) with paraformaldehyde.” Would you please explain what is that means? Does it means the BSA contains paraformaldehyde? Also, datasheet also mention that “Lyophilized whole serum”, I’m confused with these two conflicted description. Would you please help us with that?
Question By Ann
The antigen for the 5-HT Rabbit and Goat Antibodies is made using Fraction V BSA, Paraformaldehyde, and Serotonin creatinine sulfate. The serotonin and BSA are coupled together using the paraformaldehyde, in order to cross-link. Excess paraformaldehyde is then removed from the material by dialyzing to phosphate buffered saline (PBS). The material is then lyophilized. 5-HT is not a peptide or protein it is an indole-amine. When it is coupled to carrier it's structure changes. It sees 5-HT coupled to tissue proteins with paraformaldehyde.
Whole serum means that the serum from the host animal (rabbit or goat) was not affinity purified.
Lyophilization means the liquid antibody was placed in a machine to remove all the water. What remains in the vial is a powder, which is very stable and not temperature sensitive. This powder is then reconstituted by the customer to add back the water.
