    摘要: A modified form of beetle luciferase, which has been engineered for improved genetic reporting, is disclosed. The modified form contains one or more new features. Chief among these is removal of the peroxisomal translocation sequence to yield a cytoplasmic form of the enzyme. Other changes include removal of potentially interfering restriction sites and genetic regulatory sites from the gene, improvement of the codon usage for mammalian cells. The modified luciferase reporter enzyme is also devoid of potential N-glycosylation targets to minimize post-translational modification and remains in the cytoplasm of host cells to optimize substrate availability.

    摘要: Luciferase enzymes with greatly increased thermostability, e.g., at least half lives of 2 hours at 50° C., cDNAs encoding the novel luciferases, and hosts transformed to express the luciferases, are disclosed. Methods of producing the luciferases include recursive mutagenesis. The luciferases are used in conventional methods, some employing kits.

    摘要: The invention provides surfactant compounds of formulas I-IX, which can be used in methods for aiding the solubilization, digestion, preparation, analysis, and/or characterization of biological material, for example, proteins or cell membranes. The compounds can also aid in the recovery of peptides generated during protein digestion, particularly for in-gel digestion protocol. Additionally, the compounds can improve enzymatic protein deglycosylation without interfering with downstream sample preparation steps and mass spectrometric analysis. The compounds can be specifically useful as digestion aids that can be decomposed by an acid, by heat, or a combination thereof. Decomposition of the surfactants allows for facile separation from isolated samples, and/or allows for analysis of the sample without interfering with the sensitivity of various analytical techniques.
