Table 1.

The characteristics of the Aequorea-based Cerulean and Venus, and the Clavularia-based mTFP.

FP Ex (nm) Em (nm) Quantum yield Intrinsic brightness R0 with Venus
Cerulean 433 475 0.62 27 54 Å
mTFP 462 492 0.85 54 61 Å
Venus 515 528 0.57 53 NA

Intrinsic brightness is the product of quantum yield × extinction coefficient (see Ref. 5). R0 with Venus is determined by R0 = 0.211 [(k2)(n−4)(QYD)| (Jλ)]0.1667. NA is not applicable.
