Title: David R Hurwitz: Innovator in Human Serum Albumin Expression Constructs

Introduction

David R Hurwitz is an accomplished inventor based in Wyndmoor, PA (US). He is known for his significant contributions to the field of biotechnology, particularly in the development of DNA constructs for human serum albumin expression.

Latest Patents

Hurwitz holds a patent for a "Human serum albumin expression construct." This invention provides DNA constructs that include a promoter DNA sequence and a DNA sequence coding for human serum albumin. In one embodiment, the human serum albumin sequence comprises at least one, but not all, of the introns found in the naturally occurring gene encoding for the HSA protein. Additionally, the DNA constructs may include a 5' regulatory sequence that directs the expression and secretion of HSA protein in the milk of a transgenic animal. Preferably, the promoter gene is a milk protein promoter sequence such as β-lactoglobulin. The invention also encompasses transgenic animals that secrete HSA in the milk of lactating females, as well as vectors that comprise the constructs.

Career Highlights

Throughout his career, Hurwitz has worked with notable companies, including Rhone-Poulenc Rorer Pharmaceuticals Inc. and Peri Development Applications (1985) Ltd. His work has significantly impacted the biotechnology sector, particularly in the area of protein expression.
