Human Beta-endorphin (BEP) ELISA Kit

Manufactured by Assay Genie, this immunoassay kit is designed to measure levels of beta-endorphin (BEP), an endogenous opioid peptide that plays a role in pain regulation, stress response, and mood modulation. The kit is for research use only.

Reactive with human samples, the kit is validated for use with serum, plasma, tissue homogenates, cell culture supernatants, and other biological fluids. It uses a colorimetric detection method with specificity for natural and recombinant human beta-endorphin. The manufacturer states a detection range of 15.6-1000 pg/mL, a sensitivity of 10 pg/mL, an intra-assay CV of 6.8%, and an inter-assay CV of 9.2%. Recovery averages 101% in serum (range 95-107%) and 103% in plasma (range 97-109%).

Beta-endorphin is implicated in conditions such as chronic pain, addiction, and mood disorders, and is described as an agonist of the opioid receptors, with evidence suggesting it serves as the endogenous ligand of the μ-opioid receptor.
