Abstract
Unlike DNA profiling, mRNA profiling is greatly affected by external factors. To analyze the influence of different stain carriers on the detectability of mRNA markers from bloodstains, this study examined 10 carriers, including a knife, cotton swab, paper, plastic, leather, cement, chopsticks, clothes, ceramic block, and wall. After detecting five specific mRNA markers (HBA, HBB, ALAS2, GYPA, and SPTB) and the housekeeping gene B2M in peripheral blood samples, no statistically significant differences in the effects of the carriers were found. The results suggest that when performing mRNA testing on bloodstains, the effect of the stain carrier has little influence.
