Assay Principle
Resistin (RETN) is a regulatory protein expressed in mouse tissues and biological fluids. It is also referred to as ADSF; FIZZ3; RETN1. Dysregulation of RETN has been implicated in metabolic regulation and endocrine signaling, making it a relevant biomarker for investigational studies.
Quantitative measurement of RETN enables researchers to characterize its abundance in Serum, Plasma, Tissue Homogenate, Cell Lysate, Cell Culture Supernatant and correlate levels with experimental conditions. Studies investigating RETN have contributed to the understanding of obesity & adipokines, disease pathogenesis, and therapeutic target validation.
This sandwich ELISA kit provides a validated, reproducible format for RETN quantification across a defined standard curve range of 0.312-20ng/mL. The assay supports experimental workflows in Metabolic & Endocrine Research research.
Kit Components
Each kit contains sufficient reagents for one 96-well plate (approximately 40 samples in duplicate with standard curve):
Pre-coated 96-well microplate (capture antibody), HRP-conjugated detection antibody, recombinant standard protein, sample/standard diluent, concentrated wash buffer, TMB substrate solution, stop solution, and product manual.

Assay Procedure Summary
Add samples and standards to pre-coated capture antibody wells and incubate. Wash, add HRP-conjugated detection antibody, and incubate. Wash again, add TMB substrate, and stop the reaction. Read absorbance at 450 nm (reference 540–570 nm). Interpolate sample concentrations from the standard curve using a 4-parameter logistic (4-PL) fit.
Pre-warm all kit components to room temperature (18–25 °C) for 30 minutes before starting. Run all samples in duplicate. Centrifuge samples at ≥1,000 × g before use to remove particulates.

This kit is validated for serum and plasma. Centrifuge samples at ≥1,000 × g for 15 min to remove particulates. Avoid hemolyzed, lipemic, or heat-inactivated samples. Pre-dilute samples within the linear range before committing full plates.
Minimum detectable concentration: 0.114ng/mL. Quantitative standard curve range: 0.312-20ng/mL. Samples above the upper limit must be diluted; near-lower-limit samples require duplicate measurement.
A typical sandwich ELISA protocol for this kit requires 3.5–5 hours. Pre-warm reagents to room temperature (18–25 °C) for at least 30 minutes before starting and prepare standard dilutions while the capture plate equilibrates.
A standard microplate spectrophotometer set to 450 nm (reference: 540–570 nm) is required. An automated plate washer reduces wash-step variability. Calibrate and warm up your reader before measuring. Blank using the zero-standard or buffer-only well before constructing the standard curve.
Store the unopened kit at 2–8 °C until the expiry date. Shelf life: Traditional: 12 months | Ready-to-use: 16 months from date of manufacture. Reconstituted standard is stable at 4 °C for ≤1 week; prepare fresh for critical experiments.
