查询词典 diagnosis

The experiment shows that human pancreatic cancer cell line Patu 8988 has GGT→GTT mutation at codon 12. The method of PCR-SSP is rapid, convenient, economical and high specific for detecting K-ras gene point mutation. The goal in the long term is to develop a simple and useful clinical procedure for early diagnosis and differential diagnosis of pancreatic cancer.
