Bin1 mRNA expression detected by TaqMan quantitative real-time RT-PCR. A. In pigs 1, 3 and 4, bin1 mRNA was more abundant in the LD than in the psoas. In pig 2, bin1 expression in both muscles was similar. Pigs 1 to 3 were 22-week-old Berkshires, and pig 4 was a 7-week-old cross breed. B. Although ubiquitous, bin1 expression was by far most abundant in the brain and heart. Error bar = standard deviation.
