Latest Patents

Sangeetha holds a patent for a "Method for large scale plasmid purification." This process involves the large-scale isolation and purification of plasmid DNA from microbial fermentations. The method utilizes a rapid heating technique to induce cell lysis, effectively separating genomic DNA, proteins, and other debris while preserving the plasmid in solution. By suspending microbial cells in a buffer and heating the suspension to approximately 70-100°C in a flow-through heat exchanger, excellent lysis is achieved. The subsequent centrifugation of the lysate results in a pellet containing cell debris, protein, and most genomic DNA, while the plasmid remains in the supernatant. This invention offers numerous advantages, including higher product recovery compared to chemical lysis, inactivation of DNases, operational simplicity, and scalability. Sangeetha has 1 patent to her name.
