p53 antibodies in the sera of lung cancer patients: comparison with p53 mutation in the tumour tissue.

Abstract excerpt

This study examined the sensitivity and specificity of serum auto-antibodies to p53 protein as a non-invasive marker of p53 genetic alterations or protein accumulation in lung cancer cases. A sensitive ELISA to detect serum p53 antibodies was developed and used to examine sera from 186 patients undergoing pulmonary surgery for a suspected lung cancer. Target antigens in ELISA were wild-type p53 protein and 5...
