Title: Irina Esikova: Innovator in Protein Purification

Introduction

Irina Esikova is a prominent inventor based in Fremont, CA (US). She has made significant contributions to the field of protein purification, particularly focusing on interferon-beta (IFN-β). With a total of 2 patents, her work has advanced the methods used in pharmaceutical compositions.

Latest Patents

Irina's latest patents include innovative methods for the purification and recovery of interferon-beta. One of her notable patents describes improved methods for purification, where substantially purified IFN-β is precipitated and then dissolved in a guanidine hydrochloride (HCl) solution. The renaturation of the protein occurs by dilution with a suitable buffer. Additionally, a similar purification method is provided that does not include the precipitation step. After renaturation, residual guanidine HCl is removed by diafiltration or dialysis with a pharmaceutically acceptable buffer, resulting in pharmaceutical compositions comprising substantially monomeric IFN-β.
