Table 1. Comparison of CaBP expression levels in mouse cochlea at P7 and P21 by qRT-PCR.

	ΔCt values ± standard deviation
	P7	P21	p—value (by t-test)
CaBP1	5.94±0.32	4.83±0.29	< 0.0001
CaBP2	6.76±0.28	6.26±0.37*	0.29
CaBP4	13.02±0.42#	12.82±0.38#	0.88
CaBP5	19.72±1.51#	17.84±0.75#	< 0.05

ΔCt values were determined as described in Materials and Methods.

*, p <0.01

^#, p <0.0001 compared to CaBP1 at same age (by one-way ANOVA and post-hoc Bonferroni’s multiple comparisons test). For each assay, n = 8 biological replicates.
