Phospho-L-Tyrosine Disodium Salt
In diagnostic reagent manufacturing, Phospho-L-Tyrosine Disodium Salt is incorporated into in vitro diagnostic (IVD) kits as a calibrator or control to detect disease-related phosphotyrosine biomarkers, such as phospho-EGFR (non-small cell lung cancer), phospho-JAK2 (myeloproliferative disorders), and phospho-PD-1 (immunotherapy response monitoring), ensuring assay accuracy and reproducibility. It also plays a role in quality control for diagnostic antibodies, validating the specificity of phospho-tyrosine antibodies to prevent cross-reactivity with non-phosphorylated tyrosine or other phosphorylated amino acids (e.g., phospho-serine, phospho-threonine).
