Title: The Innovative Contributions of Evelyn Nario

Introduction

Evelyn Nario is a prominent inventor based in Chino Hills, California. She has made significant contributions to the field of protein purification, particularly focusing on alpha-1-proteinase inhibitor (alpha-1-PI). With a total of 2 patents, her work has the potential to impact various applications in biotechnology and medicine.

Latest Patents

Evelyn Nario's latest patents include a process for increasing the yield of a protein that has been subjected to purification. This innovative process involves providing an impure protein fraction containing alpha-1-PI, which is then suspended in an aqueous solution at pH 6. Insoluble proteins are recovered and resuspended in an aqueous solution at pH 8.5. Polyethylene glycol (PEG) is added to precipitate alpha-2 proteins. Subsequently, zinc chloride (ZnCl2) is introduced to precipitate crude alpha-1-PI from the PEG supernatant. The crude alpha-1-PI is resolubilized and applied to an anion-exchange medium, allowing for the recovery of a fraction comprising alpha-1-PI. The purified alpha-1-PI obtained through this process exhibits a specific activity of about 1.0 units/OD280.

Another notable patent by Nario focuses on the separation of alpha-1-proteinase inhibitor from COHN IV1. This process mirrors the previous one, emphasizing the purification of alpha-1-PI from impure protein fractions, showcasing her expertise in protein chemistry.
