    摘要: The present invention provides a highly glycosylated iduronate-2-sulfatase enzyme comprising an iduronate-2-sulfatase polypeptide with at least 5 kilodalton (kDa) more sugar than iduronate-2-sulfatase purified from a natural source, e.g. human liver. The present invention also provides an enzymatically active polypeptide fragment or variant of such a highly glycosylated iduronate-2-sulfatase. The present invention further provides an isolated nucleic acid encoding iduronate-2-sulfatase, as well as an expression vector, a host cell and a method for producing the present highly glycosylated iduronate-2-sulfatase enzyme. In one embodiment the present invention is directed to a method for producing a glycosylated iduronate-2-sulfatase enzyme which comprises culturing a host cell containing a nucleic acid encoding an enzymatically active iduronate-2-sulfatase polypeptide wherein the host cell glycosylates the polypeptide to a greater degree than a native iduronate-2-sulfatase polypeptide expressed by a natural human liver cell.

    摘要: This method for detecting a target nucleic acid sequence involves amplification and detection in the same vessel and comprises: (a) amplification of the target nucleic sequence in a vessel which is provided with a solid phase capture probe comprising a nucleic acid sequence capable of hybridizing to at least a portion of said amplified target nucleic acid sequence, said capture probe being incapable of participating or not participating in standard nucleic acid sequence amplification processes, (b) bringing a sample suspected of comprising said target nucleic acid sequence into contact with said capture probe under conditions which allow said amplified target nucleic acid sequence to be bound by said capture probe, and (c) detecting the presence of bound target nucleic acid sequence. In a further aspect, the present invention provides an assay system or kit, for detecting a target nucleic acid sequence in a sample suspected of comprising said target nucleic acid sequence, comprising: (a) a capture probe comprising a nucleic acid sequence capable of hydridizing to at least a portion of said amplified target nucleic acid sequence, said capture probe being immobilized on a solid phase support which forms a part of or is insertable into a container for the sample, and said capture probe being incapable of participating in standard nucleic acid sequence amplification processes, (b) reagents for amplification of said target nucleic acid sequence, and (c) means for detecting said target nucleic acid sequence, when bound by said capture probe.
