geNorm analysis of the selected candidate genes in both cultures (a) A1 and (b) A2 indicated as M values (stability values) on the Y-axis and genes on the X-axis. The lower the stability value, the more stable the gene and vice-versa. M value of less than 1 is considered appropriate for candidature as reference gene. 18S and 28S refers to RNA18S and RNA28S respectively
