Linear regression analysis between Cp values and thawing time and comparison among 6 candidate reference genes in thawed renal tissue samples.

<p>Whiskers illustrate the standard deviation of Cp values. N = 10 at each time point. The regression coefficients of <i>ACTB</i>, <i>B2M</i>, <i>GAPDH</i>, <i>HPRT1</i>, <i>PPIA</i>, and <i>TBP</i> are 0.072, 0.087, 0.119, 0.121, 0.100, and 0.052, respectively. All the <i>p</i> values <0.05.
