Study of the dynamics of the activity and stability of total IgG samples of different concentrations in blood serum samples diluted with distilled water
The publication presents the results of an experimental study of the dynamics of the activity and stability of total IgG in blood serum samples of donors in various dilutions in extracts based on distilled water, stored at a temperature of +4°C. Measurements were made in blood serum samples with high, medium and low total IgG content twice during a working day for three days using a quantitative enzyme-linked immunosorbent assay. Regularities of decrease in activity were revealed and indicators of stability of total IgG samples were determined during the specified time interval for each concentration level. The statistically significant results obtained on the basis of the results of the carried out can be used in the production of forensic biological examinations and research in terms of establishing the species of blood traces by the method of quantitative enzyme-linked immunosorbent assay.
