Human Proenkephalin (PENK) ELISA Kit

Quantitative measurement of proenkephalin in human samples is enabled by this 96-assay immunoassay kit from Assay Genie. The assay targets the PENK precursor protein, which is processed into enkephalin opioid peptides and serves as a circulating biomarker of renal function in research contexts.

Investigators studying acute kidney injury, sepsis-associated nephropathy, and cardiorenal syndrome frequently evaluate PENK as an early indicator of declining glomerular filtration rate. Research teams comparing proenkephalin concentrations against creatinine, cystatin C, and NGAL benefit from the kit's quantitative readout for cohort stratification and biomarker discovery work.

Each kit provides reagents sufficient for 96 determinations in a microplate format, supporting medium-throughput screening of clinical specimens. The procedure is intended for research use only and integrates into standard absorbance-based workflows common in translational laboratories.
