TABLE 2.

Composition of fusion proteins

Fusion name Composition (fluorophore-linker-fluorophore) Linker length (aa) Protease sensitivity Linker type (aa motifs)
fCasp3,s EGFP-linker23-mRFP1 23 Casp-3 S-G
fCasp3,l RsGFP-linker48-tdimer2(12) 48 Casp-3 A-G/S-G
finert,s EGFP-inert23-tdimer2(12) 23 inert A-G/S-G

The names of fusion constructs indicate the design of their protein linkers according to proteolytic sensitivity (inert; Casp-3) and linker length (short, 23 aa; long, 48 aa).
