Title: Alexandra Lein: Advancing Enzymatic Determination of HbA1c

Introduction:

Meet Alexandra Lein, a skilled innovator based in Diez, Germany, who has taken significant strides in the field of enzymatic determination of HbA1c. With a passion for improving healthcare diagnostics, Lein has made notable contributions through her patented inventions and collaborative efforts within the industry.

Latest Patents:

One of Lein's recent patents focuses on a method for determining the amount of glycated hemoglobin (HbA1c) through enzymatic processes. This method involves hemolyzing erythrocytes if necessary and subsequently contacting the released hemoglobin with a proteolytic agent. The resulting glycated hemoglobin degradation products are then quantified to determine HbA1c levels. To ensure the stability of the chemical compounds required for this reaction, Lein proposes utilizing an inactivated protease as the specific proteolytic agent. By activating the protease in situ, the process and reagents employed in this method exhibit sufficient stability.

In another patent, Lein further refines the enzymatic determination of HbA1c. This method also includes hemolysis of erythrocytes if required, contact with a proteolytic agent, and quantification of glycated hemoglobin degradation products. The importance of stabilizing the unfolded hemoglobin at an extremely low pH range of 1 to 3 is highlighted, and suitable stabilizers are incorporated into the hemolysis solution to achieve this goal. Additionally, Lein proposes the use of specific phosphine compounds and/or thio compounds to stabilize the leuco dye employed in the determination of HbA1c.
