Residual DNA Quantification Kit-Pichia Pastoris

Pichia pastoris, also known as Komagataella phaffii, is a methylotrophic yeast that has attracted much attention for its versatile and efficient recombinant protein production system. A significant advantage of Pichia pastoris over other expression systems such as Escherichia coli and Saccharomyces cerevisiae is its ability to undergo post-translational modifications. This includes glycosylation, disulfide bond formation, and proteolytic processing, which are essential for the functionality and stability of many eukaryotic proteins. In addition, Pichia pastoris can be cultured in simple, specific media, allowing for cost-effective and scalable production processes. Yeast can be grown to very high cell densities in bioreactors, which facilitates industrial-scale production. This makes Pichia pastoris an ideal host for the production of drugs, enzymes, and other valuable proteins. However, a critical issue in biopharmaceutical production is the presence and quantification of residual host cell DNA in the final product. Residual host cell DNA is a process-related impurity that originates from the genome of the host organism used to produce the biologic. Regulatory agencies have set strict limits on the acceptable levels of residual DNA in biopharmaceutical products due to potential risks such as immunogenicity, carcinogenicity, and infectivity. Ensuring that these levels are within permissible limits is critical for the safety and efficacy of therapeutic products. The Residual DNA Quantification Kit designed specifically for Pichia pastoris meets this critical need. It provides a reliable, sensitive, and specific method to quantify trace amounts of Pichia pastoris DNA in pharmaceutical and biotech formulations.
