5-HT7 Antibody Summary

• Immunogen: This antibody was developed by immunizing rabbits with a mixture of synthetic peptides corresponding to amino acids 13-28 of the rat 5-HT7R (AAA42134.1).
• Specificity: This sequence is identical for 5-HT7R splice variants in the rat (5-HT7Ra/b/c), human (5-HT7Ra/b/d) and human 5-HT7, the mouse 5-HT7R. It is 93% conserved with dog 5-HT7Ra/b, and 81% conserved with pig 5-HT7R. The 5HT7 antibody recognizes all described 5HT7 receptor splice variants.
• Isotype: IgG
• Clonality: Polyclonal
• Host: Rabbit
• Gene: HTR7
• Purity: Protein G purified

Applications/Dilutions

• Dilutions:
  • Western Blot 1-2 ug/ml
  • Immunocytochemistry/Immunofluorescence 1:10-1:2000
• Application Notes: In human brain, a 50 kDa band is observed. Both 45 kDa and 50 kDa bands have been observed in various human glioblastoma cell lines and in the human microglial MC-3 cell lines. Bands in the 45-50 kDa range correspond to the predicted molecular weight for the 5HT7 receptor. The 5HT7 receptor also has putative sites for N-linked glycosylation and phosphorylation which may lead to variations in observed molecular weights. Use in Immunocytochemistry/Immunoflourescence was reported in the literature (PMID: 17940054) The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.
• Theoretical MW: 54 kDa.
  Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Background

Receptors for serotonin (5-hydroxytryptamine, 5-HT) are classified into seven major classes (5-HTR1-7), based on structural, functional and pharmacological criteria (Hoyer et al, 1994). The 5-HT7 receptor (5-HT7R) is a seven-transmembrane-domain G-protein-coupled receptor that has important roles in regulating diverse biological process in the central and peripheral nervous systems (reviewed in Hedlund and Sutcliffe, 2004). Receptors for serotonin (5-hydroxytryptamine, 5-HT) are classified into seven major classes (5-HT1-7), based on structural, functional and pharmacological criteria (Hoyer et al, 1994). Sequence alignment shows a high degree of interspecies 5-HT7R homology (>90%), and a low homology with other 5-HTRs.
