In vitro stability of the immunoreactivity of the ovarian cancer-associated antigen CA 125.


A commercially available two-site solid phase radio-immunoassay was used to study the influence of time and temperature on the in vitro stability of CA 125. In whole blood samples stored at 20 degrees C the CA 125 immunoreactivity increased significantly after 2 days of storage. However, serum could be stored at 20 degrees C for 3 days and at -20 degrees C… (More)
