Creative Biogene can provide a variety of protein purification technical services, including lab-scale protein purification, large-scale protein purification, fusion tag protein purification, and tag-free protein purification. Protein purification resins and prepacked columns are also available. Protein purification at the lab scale bridges the gap between small-scale exploratory protein purification and high-throughput operations, such as industrial-scale manufacturing. Each stage of protein purification presents different challenges during scale-up, a result of prolonged fermentation times and higher cell densities in large-scale cell cultures.
