Development of a homogeneous immunoassay system using protein A fusion fragmented Renilla luciferase


, : Development of a homogeneous immunoassay system using protein A fusion fragmented Renilla luciferase. Analyst 137(5): 1085-1089

A homogeneous immunoassay system was developed using fragmented Renilla luciferase (Rluc). The B domain of protein A was fused to two Rluc fragments. When complexes between an antibody and fragmented Rluc fusion proteins bind to target molecules, the Rluc fragments come into close proximity and the luminescence activity of fragmented Rluc is restored by complementation. As proof-of-principle, this fragmented Rluc system was used to detect E. coli homogeneously using an anti-E. coli antibody.

The ability of HeLa DNA polymerase alpha to utilize gapped PM2 DNAs for synthesis in a model base excision DNA repair scheme was examined. Partially depurinated PM2 DNA was incised on the 5' side of apurinic sites with HeLa apurinic/apyrimidi...

The suprachiasmatic nucleus is commonly considered to contain the main pacemaker of behavioral and hormonal circadian rhythms. Using whole-cell patch-clamp recordings, the membrane properties of suprachiasmatic nucleus neurons were investigated in...

Achiasma in humans causes gross mis-wiring of the retinal-fugal projection, resulting in overlapped cortical representations of left and right visual hemifields. We show that in areas V1-V3 this overlap is due to two co-located but non-interacting...
