    • A method for expressing a heterologous protein in a prokaryotic host cell, comprising the steps of: (a) providing a DNA vector having: (1) a control region operatively linked to a first genetic element encoding a carrier protein capable of expression in the host cell, and (2) a second genetic element encoding the heterologous protein, the second element being embedded within the first element such that the first and second elements are contiguous and in the same reading frame; (b) transforming the host cell with the DNA vector; and (c) expressing a fusion protein of the heterologous protein and the carrier protein, wherein the heterologous protein is joined at its N-terminus to a first domain of the carrier protein and at its C-terminus to a second domain of the carrier protein, and also a method for confirming intact expression of heterologous proteins, as well as fusion proteins, DNA constructs, plasmid vectors and transformed host cells relating to the above methods.

    • This invention provides a method, a reagent, and a kit for detecting herpesvirus-specific IgM antibodies indicative of recent infection while preventing detection of low levels of herpesvirus-specific IgM antibodies present in individuals of low risk. The invention also provides a reagent for use in detecting herpesvirus-specific IgM antibodies indicative of recent infection while preventing detection of low levels of herpesvirus-specific IgM antibodies present in individuals of low risk. The method of this invention comprises the steps of: (a) providing a solid phase containing at least a portion of a herpesvirus antigen; (b) introducing a patient specimen to the solid phase of step (a); (c) introducing at least one peptide capable of specifically binding IgM antibodies to herpesvirus to the solid phase of step (a); d) allowing IgM antibodies to herpesvirus to specifically bind to the portion of antigen of herpesvirus and the peptide capable of specifically binding IgM antibodies to herpesvirus to the solid phase; and (e) determining the level of IgM antibodies to herpesvirus in the patient specimen.
    • 本发明提供了一种用于检测指示最近感染的疱疹病毒特异性IgM抗体的方法,试剂和试剂盒,同时防止存在于低风险个体中的低水平疱疹病毒特异性IgM抗体。 本发明还提供了用于检测指示最近感染的疱疹病毒特异性IgM抗体的试剂,同时防止检测低风险个体中存在的低水平疱疹病毒特异性IgM抗体。本发明的方法包括以下步骤:(a )提供含有至少一部分疱疹病毒抗原的固相;(b)将患者标本导入步骤(a)的固相;(c)将至少一种能够将IgM抗体特异性结合疱疹病毒的肽引入到 步骤(a)的固相; d)允许疱疹病毒的IgM抗体特异性结合疱疹病毒抗原部分和能够将IgM抗体与疱疹病毒特异性结合至固相的肽; 和(e)确定患者标本中疱疹病毒IgM抗体的水平。
