An isolated polynucleotide encoding a modified luciferase polypeptide and novel coelenterazine-based substrates. The OgLuc variant polypeptide has at least 60% amino acid sequence identity to SEQ ID NO: 1 and at least one amino acid substitution at a position corresponding to an amino acid in SEQ ID NO: 1. The OgLuc variant polypeptide has at least one of enhanced luminescence, enhanced signal stability, and enhanced protein stability relative to the corresponding polypeptide of the wild-type
Oplophorus

The present invention provides, among other things, imidazo[1,2-α]pyrazine derivatives according for Formula (Ia) or Formula (Ib). The derivatives are useful in any method which other coelenterazines have been used. For example, the derivatives may be used in a bioluminogenic method to detect the presence of certain compounds or molecules.
