摘要:
The invention relates to compounds, which are useful for intramolecular fluorescence resonance energy transfer (FRET), comprising the oxidized form of a carbaNADH-based first fluorophore and a second fluorophore that is excitable at a wave-length of between 445 to 540 nm and that has an emission maximum of greater than 560 nm, and methods, kits and compositions related thereto.
摘要:
The present disclosure provides an aqueous composition comprising a purified thermostable polypeptide with biological activity, and a purified thermolabile water-soluble substance which in a functional conformation at a permissive temperature absorbs light and/or exhibits fluorescence, wherein the maximal permissive temperature of the polypeptide is above the maximal permissive temperature of the substance. The present disclosure further provides methods employing such a composition, and kits containing ingredients to form such a composition.
摘要:
The invention relates to recombinant proteinase K and to a method for producing recombinant proteinase K, which is characterised by the following steps: a) transformation of a host cell containing a recombinant nucleic acid that codes for the zymogenic precursor of the proteinase K, b) cultivation of the host cell in such a way that the zymogenic precursor of proteinase K occurs in the form of inclusion bodies in said host cell, c) isolation of the inclusion bodies and re-naturing under conditions, from which the protease part of the zymogenic precursor emerges in its natural conformation, d) activation and purification of the re-natured proteinase K.
