Table 2. Expression of lactoferrin receptor in rat cornea.

	GAPDH	LRP1	Intelectin 1
Ct	18.40 ± 0.39	23.92 ± 0.30	37.02 ± 1.77
ΔCt	—	5.53 ± 0.44	18.62 ± 1.54
Fold Change	—	8752	1

The relative expression level of mRNAs was determined by real-time RT-PCR and was estimated using the ΔCt value. ΔCt value was calculated using Ct values of each receptor and GAPDH. If the ΔCt value is lower, the relative RNA level is higher. Fold change was calculated from the ΔCt value. The expression level of intelectin-1 was defined as 1. Results are expressed as the mean ± S.D. (n = 5).
