摘要: The invention provides method of covalently coupling two or more moieties, the method comprising: (a) providing a first moiety having covalently attached thereto (i) at least one first linker comprising a first hybridizable region and (ii) at least one first group capable of forming a covalent bond; (b) providing a second moiety having covalently attached thereto (i) at least one second linker comprising a second hybridizable region capable of hybridizing to the first hybridizable region and (ii) at least a second group capable of forming a covalent bond with the first group; (c) contacting the first and second moieties under conditions that allow the first and second hybridizable regions to hybridize and link the moieties; and (d) exposing the linked moieties to conditions that allow the formation of a covalent bond between the first and second groups.

摘要: A method of identifying an agent which modulates hydroxylation of hypoxia inducible factor (HIF), comprises contacting a HIF asparagine hydroxylase and a test substance in the presence of a substrate of the hydroxylase under conditions in which asparagine in the substrate is hydroxylated in the absence of the test substance; and determining hydroxylation of the substrate. Preferably the substrate is a HIF polypeptide comprising HIF-1α, a fragment thereof comprising Asn 803 of HIF-1α or a peptide analogue of HIF-1α or fragment thereof comprising an asparagine equivalent to Asn 803 of HIF-1α and wherein hydroxylation of Asn 803 or of a said equivalent asparagine is determined.
