Abstract: An observation vessel includes a holding portion configured to hold an observation object and an accommodation portion at least partially formed of a transparent curved surface and configured to position the holding portion. The holding portion is configured to hold the observation object at a set position separated from the curved surface toward a center of curvature of the curved surface in a first state of being positioned at a first position by the accommodation portion.

Abstract: Disclosed is a split recombinant protein that includes N-terminal and C-terminal fragments of a firefly luciferase, and a linker peptide. The N-terminal fragment is one of two fragments of a firefly luciferase split into two at a splitting position specific to the firefly luciferase. The C-terminal fragment includes a C-terminal fragment of a firefly luciferase split into two at a splitting position specific to the firefly luciferase, and 58 to 78 amino acid residues toward the N-terminal beyond the splitting position. When the N-terminal and C-terminal fragments are bound together, firefly luciferase activity is exhibited.
