Systems and methods for electrochemical point-of-care detection of hemoglobin

A method for determining analytes includes lysing the red blood cells of a whole blood sample, oxidizing the free hemoglobin in the lysed sample, and cleaving FVH from the hemoglobin A1C to form an electrochemical test solution. In one aspect, a first portion of the electrochemical test solution is reacted with fructosyl peptide oxidase and a reduced ruthenium mediator to form a first reaction product. A first electrical property of the first reaction product is measured, the measurement being indicative of hemoglobin A1C in the blood sample. In another aspect, a second portion of the electrochemical test solution is reacted with ferrocyanide to form a second reaction product. A second electrical property of the second reaction product is measured, the measurement being indicative of total hemoglobin in the blood sample. Hemoglobin A1C, total hemoglobin, and % HbA1C are determined based on the first and second electrical properties.

Synthetic protein circuits detecting signal transducer activity

Disclosed herein include methods, compositions, and kits suitable for use in detecting the activation level of a signal transducer. In some embodiments, there are provided synthetic protein circuits wherein recruitment of synthetic protein circuit components to an association location upon activation of a signal transducer generates an active effector protein. The effector protein can be configured to carry out a variety of functions when in an active state, such as, for example, inducing cell death. Methods of treating a disease or disorder characterized by aberrant signaling are provided in some embodiments.
