Assay Principle
DPEP1 (STJE0014867) is a biomarker protein expressed in human tissues and biological fluids. Dysregulation of STJE0014867 has been implicated in cellular signaling and fundamental cell biology, making it a relevant biomarker for investigational studies.
Quantitative measurement of STJE0014867 enables researchers to characterize its abundance in Serum, Plasma, Tissue Homogenate and correlate levels with experimental conditions. Studies investigating STJE0014867 have contributed to the understanding of renal biology, disease pathogenesis, and therapeutic target validation.
This sandwich ELISA kit provides a validated, reproducible format for STJE0014867 quantification across a defined standard curve range of 0.156-10ng/mL. The assay supports experimental workflows in Cell Biology research.

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. Total protocol time: approximately 3 hours.
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: 0.050ng/mL. Quantitative standard curve range: 0.156-10ng/mL. Samples above the upper limit must be diluted; near-lower-limit samples require duplicate measurement.
Total protocol time is approximately 3 hours of hands-on and incubation time. Pre-warm all reagents and prepare dilution series in advance. Set up a timer for each incubation step to maintain consistent timing across plates.
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.
Recommended storage: The whole kit may be stored at-20°C for up to 12 months from receipt. An unopened kit may be stored in the fridge at 2-8°C for up to 6 months. Once opened store individual kit contents according to co. Reconstituted standard is stable at 4 °C for ≤1 week; prepare fresh for critical experiments.
