The main technical index of this standard method is to use high-performance liquid chromatography to determine the content of immunoglobulin IgG in milk, which requires the optimization of purification and detection conditions suitable for immunoglobulin IgG. The steps to implement this work include optimization of pretreatment methods, optimization of chromatographic conditions, and analysis of detection limits, standard curves, spike recovery rates, and precision.
