Human Enkephalin (ENK) ELISA Kit

This competitive immunoassay targets endogenous opioid peptides including methionine-enkephalin and leucine-enkephalin in human specimen matrices. Researchers typically load 50 uL of sample per well, with serum samples, plasma specimens, tissue homogenates, and cell lysates validated as compatible inputs.

Reconstituted standard and conjugate should be kept refrigerated and shielded from light, while unused microwell strips remain stable in their sealed pouch at 4 degrees C. Each kit contains materials for 96 determinations, including a pre-coated plate, conjugate, lyophilized standards, wash buffer, and substrate solution. The protocol supports research applications in neuroscience, analgesia studies, and investigations of endogenous opioid signaling. Provided as a complete, ready-to-use microplate kit manufactured by Assay Genie.
