We developed a standard protocol for quality assessment of low amount RNA from the cells obtained by laser capture microdissection(LCM).Three gastric noncancerous tissues were cryo-sectioned,stained with Cresyl Violet,and pathologically rechecked.Epithelial cells were obtained by LCM and RNA was isolated.Agilent 2100 bioanalyzer was used to check the RNA quality.To validate the results from 2100 bioanalyzer,RT-PCR was performed with six genes at both 5′ and 3′end-regions of different abundance(EF1A and ATCB...
