Assay Principle
Parathyroid Hormone (PTH) is a hormone expressed in rat tissues and biological fluids. It is also referred to as iPTH; Intact Parathyroid Hormone; Parathormone. Dysregulation of PTH has been implicated in cellular signaling and fundamental cell biology, making it a relevant biomarker for investigational studies.
Quantitative measurement of PTH enables researchers to characterize its abundance in Serum, Plasma, Tissue Homogenate, Cell Lysate, Cell Culture Supernatant and correlate levels with experimental conditions. Studies investigating PTH have contributed to the understanding of cell signaling pathways, disease pathogenesis, and therapeutic target validation.
This competitive ELISA kit provides a validated, reproducible format for PTH quantification within the inhibition range of 3.12-200pg/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 Parathyroid Hormone concentration. Construct a standard inhibition curve from the provided reference antigen to calculate sample concentrations.
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: 1.27pg/mL. Quantitative standard curve range: 3.12-200pg/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.
