Fig. 3From: Hydroxymethylbilane synthase (HMBS) gene-based endogenous internal control for avian speciesDistribution of avian HMBS-based qPCR copy numbers in chicken tissues and organs. The DNA of eleven organs/tissues from four chickens were tested in the avian HMBS-based qPCR to determine log10 transformed HMBS copies/10 mg. Blue bar denotes the mean value of the HMBS copies in the denoted organ or tissue. Different letters (a or b) indicate significant difference (P < 0.05)Back to article page
