We conducted a comparative analysis of optimal protein isolation and purification methods used in production, with efficiency and environmental friendliness as the primary evaluation criteria. Comparative analysis involves comparing various protein isolation and purification methods across a number of key characteristics, including final product purity, yield, resource consumption, process complexity, and versatility in relation to various protein types. This approach allows us to identify the advantages and disadvantages of each method and establish optimal conditions for their most effective use. Factors influencing protein stability and activity are considered.

Efficiency assessment is based on a combination of quantitative and qualitative indicators. Quantitative indicators include target protein yield, reagent consumption, procedure duration, and process energy consumption. Qualitative indicators include the method's resistance to impurities, selectivity, reproducibility of results, and preservation of the native properties of the protein molecule. Conducting such calculations provides an objective assessment of the practical significance of the methods under study and allows us to develop universal criteria for their evaluation. The results of the analysis contribute to improving the quality of bioproducts during the optimization of biotechnology.
