Scientific background

5-HT is involved in a diverse array of physiological and biological processes. In the brain, 5-HT affects sleep, mood, appetite, anxiety, aggression, perception, pain, and cognition1. Signaling of 5-HT is mediated by receptors that are located on the cell membrane of neurons and most other cells in the body. The 5-HT2 family consists of three G-protein coupled receptors (GPCRs): 5-HT2A, 5-HT2B, and 5-HT2C2. They are transmembrane proteins consisting of seven membrane-spanning α-helical segments with an extracellular N-terminus and an intracellular C-terminus. The binding of 5-HT to one of its receptors is thought to elicit a conformational change that activates associated heterotrimeric G proteins and recruits other downstream signaling/scaffolding molecules, such as GPCR kinases and β-arrestins.

5-HT2A receptors have been found in many regions of the human brain including the cortex, brainstem, olfactory bulb, limbic system and basal ganglia3.

The 5-HT2A receptor has been implicated in many mental disorders including schizophrenia, depression, obsessive compulsive disorder (OCD), attention deficit–hyperactivity disorder (ADHD), and eating disorders such as anorexia nervosa and autism spectrum disorders4.

Guinea Pig Anti-5HT2A Receptor (HTR2A) (extracellular) Antibody (#ASR-033-GP) is a highly specific antibody directed against an epitope of the rat protein. The antibody can be used in western blot and immunohistochemistry applications. It has been designed to recognize 5-HT2A from mouse, rat and human samples.

The antigen used to immunize guinea pigs is the same as Anti-5HT2A Receptor (HTR2A) (extracellular) (#ASR-033) raised in rabbit. Our line of guinea pig antibodies enables more flexibility with our products such as multiplex staining studies, immunoprecipitation and more.
