ELISA Stop Solution - Immunoassay Applications

Strong acid protonates oxidized TMB (450nm peak) preventing further color development across cytokine, hormone, and infectious disease panels.

Immunology laboratories achieve ±5% CV across 0.1-10 ng/mL standards preventing drift during high-throughput ELISA processing.

Quality control confirms complete TMB protonation, 405/450nm ratiometric stability, and 24-month room temperature stability.
