AI Technical Summary
Existing PTH molecules are easily degraded by enzymes, oxidized, and aggregated in quality control materials, resulting in insufficient stability and affecting the accuracy and consistency of detection. Traditional chemical modification methods cannot simultaneously ensure stability and immunoreactivity.
By introducing specific amino acid substitutions into PTH molecules through site-directed mutagenesis, intramolecular disulfide bonds are formed, blocking enzymatic and oxidative pathways while retaining immunoreactivity characteristics, thus preparing liquid quality control products.
It achieves a balance between long-term stability and immunoreactivity of PTH molecules, is suitable for multiple detection platforms, meets clinical quality control needs, and is easy to industrialize.
