ABSTRACT:
Presence of free insulin receptor α-subunit in blood was discovered. Furthermore, methods for measuring the insulin receptor α-subunit was provided, the method comprising the steps of contacting the insulin receptor α-subunit in a blood sample with an antibody recognizing the insulin receptor α-subunit, and detecting the binding between the two. Measurement of the free insulin receptor α-subunit in the blood is useful for evaluating risk factors for diabetes.In addition, the measurement methods of the present invention showed that concentrations of the free insulin receptor α-subunit in the blood of diabetes or cancer patients are significantly high. Free insulin receptor α-subunit in blood is useful as a marker for diabetes or cancer.
