Assay Principle
Delta Like Protein 4 (Delta Like Protein 4) is a biomarker protein expressed in rat tissues and biological fluids. It is also referred to as Hdelta2; Drosophila Delta homolog 4. Dysregulation of Delta Like Protein 4 has been implicated in cellular signaling and fundamental cell biology, making it a relevant biomarker for investigational studies.
Quantitative measurement of Delta Like Protein 4 enables researchers to characterize its abundance in Tissue Homogenate and correlate levels with experimental conditions. Studies investigating Delta Like Protein 4 have contributed to the understanding of cell signaling pathways, disease pathogenesis, and therapeutic target validation.
This sandwich ELISA kit provides a validated, reproducible format for Delta Like Protein 4 quantification across a defined standard curve range of 0.156-10ng/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 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 tissue homogenates. 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: 0.068ng/mL. Quantitative standard curve range: 0.156-10ng/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.
