The Rat PENK (Proenkephalin) ELISA Kit is specifically designed for the precise measurement of proenkephalin levels in rat serum, plasma, and tissue homogenates. This kit offers exceptional sensitivity and specificity, ensuring consistent and accurate results for various research purposes. Proenkephalin is a key precursor protein involved in the production of endorphins, which are natural pain-relieving molecules in the body.
It plays a critical role in pain perception, stress response, and addiction, making it a valuable biomarker for studying these physiological processes and potential therapeutic interventions. With its reliable performance and wide application range, the Rat PENK ELISA Kit is an essential tool for researchers studying pain management, substance abuse, and stress-related disorders in preclinical rat models.

Step
Procedure
1
Reagent & Plate Preparation: Equilibrate reagents and TMB substrate to room temperature. Set standard, test sample and control (zero) wells on the pre-coated plate and record their positions.
2
Primary Incubation: Prepare standards, samples, blanks and load into designated wells. Incubate plate at 37°C for 90 minutes to allow antigen binding.
3
Detection Antibody Binding: Add biotin-labeled detection antibody and incubate at 37°C for 60 minutes.
4
HRP-Streptavidin Binding: Add HRP-Streptavidin (SABC) and incubate at 37°C for 30 minutes.
5
Color Development: Add TMB substrate and incubate in the dark for 10–20 minutes.
6
Stop Reaction & Reading: Add stop solution and measure absorbance at 450 nm immediately.
Sample Type
Protocol
Serum
Allow blood to clot, centrifuge at 1000 × g for 20 minutes, collect supernatant supernatant and store appropriately.
Plasma
Collect using anticoagulant tubes, centrifuge at 1000 × g for 15 minutes at 2–8°C and collect plasma.
Tissue Homogenate
Homogenize tissue in PBS with protease inhibitors, centrifuge and collect supernatant.
Cell Culture Supernatant
Centrifuge at 2500 rpm for 5 minutes and collect clarified supernatant.
Cell Lysate
Lyse cells using lysis buffer with protease inhibitors, centrifuge and collect protein supernatant.
