SpecificityConfirmed by RIA against the synthetic peptide. Human; mouse; rat. Beta-endorphin is highly conserved so cross-reactivity with other species is expected. Cross-reactivity with other opioid peptides is as follows: with Met-enkephalin 0.03%; with Leu-enkephalin 0.02%; with beta-lipotropin 0.34%.
Species ReactivityHuman, Mouse, Rat
Immunogen DescriptionSynthetic human beta-endorphin peptide (1-31 aa) conjugated to BSA.
Application DetailsA dilution of 5-10 µg/mL is recommended for immunohistochemistry using formalin fixed and paraffin embedded tissues and for 4% paraformaldehyde fixed frozen tissues. A dilution of 5-15 µg/mL is recommended for immunofluorescence. For radioimmunoassay (RIA), a working dilution of 1:10,000 is recommended. Sensitivity - 120 pg/sample; IC50-1 ng/ sample. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.

Scientific BackgroundHuman beta-endorphin is a 31 amino acid peptide cleaved from the precursor pro-opiomelanocortin (POMC). It is an endogenous opioid peptide neurotransmitter that interacts with opioid receptors.
Immunohistochemical staining in rat ventral periaqueductal grey matter (PAG). 4% paraformaldehyde fixed rat brain crystostat sections (10 µm) were incubated overnight at 4°C with Rabbit polyclonal antibody to human beta Endorphin (10 µg/mL) followed by incubation with FITC conjugated secondary antibody.
