Product Overview
The Tavolimab ELISA Kit is a competitive ELISA kit for quantitative measurement of tavolimab in serum, plasma and other biological fluid samples. The 96-well microplate is pre-coated, and the colorimetric signal is read at 450 nm.
In this competitive format, tavolimab in standards and samples competes for a limited number of binding sites in the pre-coated wells, so the optical density falls as the tavolimab concentration rises. Concentrations are calculated from the standard curve run on the same plate.

Assay Procedure (Summary)
Bring all reagents to room temperature and prepare working solutions and the standard series before starting.
- Add 100 µL standard or sample premixed with Detection A working solution (50 µL + 50 µL); incubate 1 h at 37 °C.
- Wash 3 times with 300 µL wash buffer per well.
- Add 100 µL Detection B working solution; incubate 30 min at 37 °C.
- Wash 5 times with 300 µL wash buffer per well.
- Add 100 µL Color Reagent; incubate 15 min at 37 °C, protected from light.
- Add 50 µL stop solution; the color turns from blue to yellow.
- Read the OD at 450 nm within 10 min (wavelength correction at 630 nm or 620 nm).
Total incubation time is about 1 h 45 min, plus washing steps. Required but not supplied: a microplate reader for 450 nm (correction at 630 nm or 620 nm), pipettes and tips, deionized or distilled water, a 500 mL graduated cylinder, a squirt bottle, manifold dispenser or plate washer, and tubes for standard dilutions.
Sample Preparation
- Serum: use a serum separator tube, let the sample clot for 30 minutes at room temperature, and centrifuge for 15 minutes at 1000 × g.
- Plasma: collect with EDTA, heparin or citrate as the anticoagulant and centrifuge for 15 minutes at 1000 × g within 30 minutes of collection.
- Assay samples promptly or store aliquots at -20 °C or below; avoid repeated freeze-thaw cycles.
- Serum and plasma samples: a 10-fold starting dilution in Standard Diluent is suggested; adjust it so readings fall within the standard curve.
