Abstract: The present invention provides a process and regent for analyzing annexin-V, wherein the measurement of a concentration of annexin-V can be easily carried out without need for addition of chemicals for inhibiting the bonding of various proteins with calcium ion and for adjusting a specimen solution to the specimen at a measuring stage, and a process and medicine for diagnosing an internal organ disorder based on the analyzing process and regent. A urine is brought into contact with an anti-annexin-V monoclonal antibody to perform an antigen-antibody reaction of annexin-V in the urine with the anti-annexin-V monoclonal antibody, thereby forming an annexin-V antigen/anti-annexin-V monoclonal antibody complex, and the amount of the formed annexin-V antigen/anti-annexin-V monoclonal antibody complex is quantitatively measured.

Abstract: Using human annexin-V or human annexin-V plus dog annexin-V as antigen(s), hybridoma cell lines are prepared which are capable of producing anti-annexin-V monoclonal antibodies having a binding specificity to antigenic determinant site on annexin-V as antigenic protein and belonging to immunoglobulin G class. By the hybridoma cell lines are produced the anti-annexin-V monoclonal antibodies, with which a diagnostic agent is provided for diagnosis of myocardial infarction and angina pectoris.
