Title: The Innovations of Wolf Hanisch

Introduction

Wolf Hanisch is a notable inventor based in Oakland, CA. He has made significant contributions to the field of biotechnology, particularly in the area of interleukin-2 production. With a total of three patents to his name, Hanisch has developed innovative processes that enhance the purity and recovery of this important protein.

Latest Patents

Hanisch's latest patents include "Compositions containing reduced, microbially produced interleukin-2" and "Purified, reduced recombinant interleukin-2 compositions." Both patents describe a sophisticated process for recovering microbially produced IL-2 in a highly pure form. This process involves disrupting the cell membranes of microorganisms, extracting the disruptate with a chaotropic agent like urea, and solubilizing the IL-2 using an aqueous solution of a solubilizing agent such as SDS. The IL-2 is then separated from the resulting solution through optional extraction with 2-butanol or 2-methyl-2-butanol, followed by gel filtration chromatography. The final steps include oxidizing the IL-2 and purifying the oxidized IL-2 using RP-HPLC.

Career Highlights

Throughout his career, Hanisch has worked with prominent companies in the biotechnology sector, including Cetus Corporation and Chiron Corporation. His work has significantly advanced the understanding and production of interleukin-2, a crucial component in immunotherapy and other medical applications.
