A polynucleotide encoding a modified luciferase polypeptide. The modified luciferase polypeptide has at least 60% amino acid sequence identity to a wild-typeluciferase and includes at least one amino acid substitution at a position corresponding to an amino acid in a wild-typeluciferase of SEQ ID NO: 1. The modified luciferase polypeptide has at least one of enhanced luminescence, enhanced signal stability, and enhanced protein stability relative to the wild-typeluciferase.

Synthetic oplophorus luciferases with enhanced light output

[object Object]

A polynucleotide encoding a biosensor polypeptide comprising a modified circularly-permuted thermostable luciferase and a linker linking the C-terminal portion of the thermostable luciferase to the N-terminal portion of the thermostable luciferase. The modified circularly-permuted thermostable luciferase is modified relative to a parental circularly-permuted thermostable luciferase. The linker contains a sensor region capable of interacting with a target molecule in a cell. The modified circularly-permuted thermostable luciferase has an enhanced response after interaction of the biosensor with the target molecule relative to the parental circularly-permuted thermostable luciferase in the presence of the target molecule. Alternatively, the modified circularly-permuted thermostable luciferase has an enhanced response after interaction of the biosensor with the target molecule relative to the modified circularly-permuted thermostable luciferase in the absence of the target molecule.

Mutant protease biosensors with enhanced detection characteristics

Cell lysis compositions, methods for extracting and isolating proteins and peptides from a host cells using the compositions, kits and apparatus for extracting and isolating protein and peptide molecules from host cells and for detecting for the presence of a protein or peptide. The composition allows for the extraction and isolation of proteins and peptides from host cells without the need for mechanical disruption and with or without isolation of the cells from cell medium. The composition includes at least one surfactant having a hydrophobic-lipophilic balance value in the range from about 11 to about 16; and at least one cell membrane altering compound.
