Table 1. Values of FRETR, FR, and YFP/CFP in HEK 293 cells transfected with YFP/CFP plasmids, YFP-CFP fusion plasmid, and CFP-SR-A/YFP-GRP78 plasmids.

	YFP/CFP (n = 8)	YFP-CFP (n = 8)	YFP-GRP78/CFP-SR-A (n = 33)
FRETR	1.0023±0.0289	2.2546±0.1789 a	1.2547±0.0658 b
FR	1.0085±0.1947	4.4165±0.5157 a	2.1700±0.3792 b
YFP/CFP	0.1–0.45	0.4519±0.0386	0.2951±0.0752

a, P < 0.05, compared with YFP/CFP; b, P < 0.05, compared with YFP-CFP.
