To overcome this problem, immunostaining of p53 protein was used and then PCR-FSSCP (which is more sensitive than PCR-SSCP [4]), followed by cloning and sequence analysis of abnormal DNA to demonstrate point mutations of the p53 gene. The possibility of false-positive results should be dis ...

Mutagen
In genetics, a mutagen is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer, mutagens are therefore also likely to be carcinogens. Not all mutations are caused by mutagens: so-called ""spontaneous mutations"" occur due to spontaneous hydrolysis, errors in DNA replication, repair and recombination.
