    • The present invention relates to a chemically modified mutant protein including a cysteine residue substituted for a residue other than cysteine n a precursor protein, the substituted cysteine residue being subsequently modified by reacting the cysteine residue with a glycosylated thiosulfonate. Also a method of producing the chemically modified mutant protein is provided. The present invention also relates to a glycosylated methanethiosulfonate. Another aspect of the present invention is a method of modifying the functional characteristics of a protein including providing a protein and reacting the protein with a glycosylated methanethiosulfonate reagent under conditions effective to produce a glycoprotein with altered functional characteristics as compared to the protein. In addition, the present invention relates to methods of determining the structure-function relationships of chemically modified mutant proteins. The present invention also relates to synthetic methods for producing thio-glycoses, the thio-glycoses so produced, and to methods for producing glycodendrimer reagents.
    • 本发明涉及一种化学修饰的突变蛋白,其包含半胱氨酸残基,其取代了半胱氨酸以外的残基而不是前体蛋白,随后通过半胱氨酸残基与糖基化硫代磺酸酯反应来修饰取代的半胱氨酸残基。 还提供了一种生产化学修饰的突变蛋白的方法。 本发明还涉及糖基化甲磺酸盐。 本发明的另一方面是一种改变蛋白质的功能特征的方法,包括提供蛋白质并使蛋白质与糖基化甲磺酸盐试剂在与蛋白质相比产生具有改变的功能特征的糖蛋白的条件下反应。 此外,本发明涉及确定化学修饰的突变蛋白的结构 - 功能关系的方法。 本发明还涉及用于制备硫代糖糖,如此制备的硫代糖糖的合成方法,以及制备糖苷配基体试剂的方法。

    • Disclosed are biomolecule based bioprobes that exhibit improved water solubility and mono layer-forming properties with substantially little or no aggregation that can appreciably interfere with binding of the bioprobes to a target nucleotide. The bioprobes may be used in conjunction with a suitable reporter system to detect very small quantities of biological markers. The bio-probes comprise a nucleobase sequence capable of hybridizing to a target nucleotide; and at least one charged functional group attached to said nucleobase sequence. Also disclosed are biosensors, and sensing devices that comprise the bio-probe. Further disclosed are suitable electrochemical reporter systems for use with the bioprobes. Methods of use of these devices and probes, including for the detection of target biomarkers, including biomarkers for cancer cells or pathogens, are also included.
