Abstract: An adhesive composition is provided. The adhesive composition includes a mixture (A), wherein the mixture (A) includes a first component (a), a cross-linking agent (b), and a second component (c), wherein the second component (c) includes a calcium-containing complex compound or a calcium-containing compound. Based on the total weight of the mixture (A), a content of the first component (a) is from 40 to 80 wt %, a content of the cross-linking agent (b) is from 20 to 60 wt %, and a content of the second component (c) is from 1 to 20 wt %. Specifically, the calcium-containing complex compound is selected from the group consisting of a compound represented by formula (1), a compound represented by formula (2), a compound represented by formula (3), and a compound represent by formula (4), and the calcium-containing compound is selected from the group consisting of a compound represented by formula (5) and a compound represent by formula (6).

Abstract: A fluorescent fusion protein is provided. The fluorescent fusion protein of the invention comprises a first fluorescent protein with first emission wavelength, a second fluorescent protein with second excitation wavelength and second emission wavelength, and a linker peptide linking the first fusion protein and the second fusion protein, wherein the first emission wavelength overlaps the second excitation wavelength so that the second fluorescent protein exhibits the second emission wavelength after receiving energy. The fluorescent fusion protein of the invention exhibits a stronger fluorescence in the absence of bilivirdin (BV).
