Rat ENK (enkephalin) ELISA Kit (RTFI01464)

Enkephalin (ENK) is a pentapeptide endogenous opioid neurotransmitter active throughout the central and peripheral nervous systems, where it modulates nociception, stress responses, and neuroendocrine signaling. This competitive immunoassay from Assay Genie is calibrated for rat specimens, supporting neuroscience, pharmacology, and behavioral research. The pre-coated microplate uses a competing antigen format, allowing endogenous enkephalin to be quantified against a standard curve. Each well typically receives a 50 µL sample, and the kit should be stored at 4 °C to preserve antibody and conjugate stability through the expiration date.
