Platelet expression of PEAR1 protein is related to genetic variation in PEAR1 at rs12041331. Western blotting analysis of platelet lysates (30 μg/lane) from randomly selected persons who varied by genotype (AA, AG, GG) at rs12041331. (A) Representative Western blots. (B) Summary results for platelet expression by genotype normalized to control (AG pooled mixture). (C) Platelet expression of PEAR1 protein assessed by quantitative ELISA. Results are displayed as mean ± SD; *P < .05 for difference among groups by ANOVA.
