Assay Principle
VB6 (STJE0006572) is a biomarker protein expressed in mammalian tissues and biological fluids. Dysregulation of STJE0006572 has been implicated in cellular signaling and fundamental cell biology, making it a relevant biomarker for investigational studies.
Quantitative measurement of STJE0006572 enables researchers to characterize its abundance in Serum, Plasma and correlate levels with experimental conditions. This kit recognizes VB6 in samples. No significant cross-reactivity or interference between VB6 and analogues was observed.
This competitive ELISA kit provides a validated, reproducible format for STJE0006572 quantification within the inhibition range of 1.56~100ng/mL. The assay supports experimental workflows in Cell Biology research.
Kit Components
Each kit contains sufficient reagents for one 96-well plate (approximately 40 samples in duplicate with standard curve):
Pre-coated microplate (96 wells), HRP-conjugated antigen, standard protein, sample diluent, wash buffer, TMB substrate solution, stop solution, and product manual.

Assay Procedure Summary
Add samples and HRP-conjugated antigen simultaneously to pre-coated wells and incubate. Wash, add TMB substrate, and read at 450 nm. Signal is inversely proportional to VB6 concentration. Construct a standard inhibition curve from the provided reference antigen to calculate sample concentrations. Total protocol time: approximately 2.5 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. As a competitive format, higher analyte concentration produces lower signal — dilute proportionally. Pre-dilute samples within the linear range before committing full plates.
Minimum detectable concentration: 0.94ng/mL. Quantitative standard curve range: 1.56~100ng/mL. Samples above the upper limit must be diluted; near-lower-limit samples require duplicate measurement.
Total protocol time is approximately 2.5 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: If unopened the kit may be stored at 2-8°C for up to 1 month. If the kit will not be used within 1 month, store the components separately, according to the component table in the manual.. Reconstituted standard is stable at 4 °C for ≤1 week; prepare fresh for critical experiments.
