• ELISA Kit Principle: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Proenkephalin (PENK). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Proenkephalin (PENK). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Proenkephalin (PENK), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Proenkephalin (PENK) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
• ELISA Kit Range: 78-5,000pg/mL
• ELISA Kit Recovery:

  Matrix	Recovery range (%)	Average(%)
  Serum (n=5)	93-101	97
  EDTA Plasma (n=5)	87-101	95

• ELISA Kit Reproducibility: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Proenkephalin (PENK) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Proenkephalin (PENK) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

Target Info

• Gene Symbol: Penk
• Gene Full Name: preproenkephalin
• Alias Symbols: AI326464;EN;ENK;Pe;Pen;Penk1;PPA;preproenkephalin 1;proenkephalin-A;spermatogenic-specific proenkephalin.
• NCBI Gene Id: 18619
• Protein Name: Proenkephalin-A
• Description of Target: Met- and Leu-enkephalins compete with and mimic the effects of opiate drugs. They play a role in a number of physiologic functions, including pain perception and responses to stress. PENK(114-133) and PENK(238-259) increase glutamate release in the striatum. PENK(114-133) decreases GABA concentration in the striatum.
