Title: The Innovations of Robert J Schaeper
Introduction
Robert J Schaeper is a notable inventor based in South Bend, IN (US). He has made significant contributions to the field of enzymatic activity determination, holding a total of 5 patents. His work has had a profound impact on various applications, particularly in the medical and biochemical sectors.
Latest Patents
One of Schaeper's latest patents is focused on enzyme determination with protease inactivation. This invention involves a composition and method for determining enzymatic activity or enzyme substrate concentration in a fluid test sample. The enzyme catalyzes a reaction in a reagent system, providing a detectable response indicative of the enzyme or enzyme substrate concentration. A measured amount of protease is included in the reagent composition to eliminate enzymatic activity, ensuring that the reaction producing the detectable response has a definite endpoint. This invention is particularly useful for determining leucocytes in urine, where leukocytes are lysed to release human leucocyte elastase, which hydrolyzes a chromogenic ester to produce a phenol that reacts with a diazonium salt to form a colored azo dye.
Another significant patent by Schaeper is related to a glass/cellulose combination as a protein reagent. This improvement enhances the method of determining protein in an aqueous fluid, such as urine, by contacting the fluid with a reagent system of a buffer and a protein error indicator. The determination is carried out in the presence of this glass/cellulose combination, leading to more accurate results.
