Fig. 4From: Growth arrest specific gene 2 in tilapia (Oreochromis niloticus): molecular characterization and functional analysis under low-temperature stressThe quantitative RT-PCR analysis of gas2 expression in tilapia different tissues in 30 °C. The β-actin gene was used as an internal control to calibrate the cDNA template for all the samples. Data are expressed as the mean ± SD (n = 3)Back to article page
