Presentation for the first research co-ordination meeting on development of kits for radioimmunometric assays for tumour markers

Radioimmunoassay and Labeled Compound Lab. is the earliest and biggest center which supply RIA reagents in China. It started the research on RIA reagents in the middle of 1970's. Now it can produce more than 80 kinds of RIA kits including thyroid function and newborn screening, tumor markers, kidney function, diabetes-related, fertility and pregnancy monitoring and diagnosis of hepatitis B and C. There are over 1000 hospitals and research organizations using the reagents. Cancer is a disease which endanger human life. There are about 1.6 million new cancer patient and 800 thousand persons died of cancer every year in our country. The laboratory has been paying attention to development of tumor markers RIA reagents since we started the research on RIA reagents. The first kit produced was Rocket Electrophoresis Radioautograph of AFP. In 1980's it developed AFP, CEA, HCG and Ferritin RIA kits. Now RIA reagents for tumor markers have become important part of our products . Besides the products above mentioned it also can produce calcitonin RIA, thyroidglobulin RIA and CA125 IRMA. In early 1990's it established a monoclonal antibody Lab. and this Lab. have been working for the preparation of the monoclonal antibody to tumor markers
