  The present invention relates to an improved macromolecule transduction domain (MTD), which facilitates permeating the cell membrane of a biologically active molecule, having enhanced cell permeability. Specifically, an improved MTD according to the present invention, compared to an existing MTD, can transmit various types of biologically active molecule from inside the body and inside a test tube more effectively, and thus can be effectively used in a method to genetically alter a biologically active molecule so as to have cell permeability or in a method to transport a biologically active molecule into a cell, or the like. Additionally, the improved MTD can be very useful in development of new drugs and incrementally modified drugs as uses of the improved MTD are possible in drug delivery systems, recombinant protein vaccines or DNA/RNA therapeutic agents, gene or protein therapies, and pharmacologically or medically useful protein production or medical, pharmacological and pharmaceutical compositions.

  本发明涉及一种改进的大分子转导结构域（MTD），它有利于生物活性分子渗透细胞膜，具有更强的细胞渗透性。具体地说，与现有的 MTD 相比，根据本发明改进的 MTD 可以更有效地从体内和试管内转运各种生物活性分子，因此可以有效地用于遗传改变生物活性分子以使其具有细胞渗透性的方法，或用于将生物活性分子转运到细胞内的方法等。此外，改进型MTD在新药和增量改良药物的开发中也非常有用，因为改进型MTD可用于给药系统、重组蛋白疫苗或DNA/RNA治疗剂、基因或蛋白疗法、药理学或医学上有用的蛋白生产或医疗、药理学和药物组合物中。
• SOLID-PHASE IMMOBILIZATION OF MICROBIAL TRANSGLUTAMINASE MTG ON MICROBEADS FOR PROTEIN CONJUGATION

  Site-specific modification of proteins with microbial transglutaminase (MTG) is a powerful and versatile strategy for a controlled modification of proteins under physiological conditions. We present evidence that solid-phase microbead-immobilization can be used to site-specifically and efficiently attach different functional molecules important for further downstream applications to proteins of therapeutic relevance including scFV, Fab-fragment and antibodies. We demonstrate that MTG remained firmly immobilized with no detectable column bleeding and that enzyme activity was sustained during continuous operation, which allowed for a convenient recycling of the enzyme, thus going beyond solution-phase MTG conjugation. In addition it is showed that immobilized MTG shows enhanced selectivity towards a certain residue in the presence of several reactive residues which are all targeted if the conjugation was carried out in solution.

  用微生物转谷氨酰胺酶（MTG）对蛋白质进行位点特异性修饰是在生理条件下对蛋白质进行可控修饰的一种强大而多用途的策略。我们提出的证据表明，固相微珠固定化技术可用于定点、高效地将对进一步下游应用非常重要的不同功能分子附着到具有治疗意义的蛋白质上，包括 scFV、Fab 片段和抗体。我们的研究表明，MTG 被牢牢固定，没有检测到色谱柱渗漏，而且在连续操作过程中酶的活性得以保持，从而方便了酶的再循环，超越了溶液相 MTG 连接。此外，研究还表明，如果在溶液中进行缀合，固定化的 MTG 会在存在多个反应残基的情况下对某个残基显示出更强的选择性，而这些反应残基都是缀合的目标。
• METHOD FOR THE DETECTION AND/OR QUANTIFICATION OF LUPIN BETA-CONGLUTIN ALLERGEN PROTEINS

  The present invention provides an improved antibody, method and kit for the specific detection and/or quantification of the main allergen proteins of lupin seeds, namely beta-conglutins, preferably in foodstuffs. The method of the invention is preferably based on an ELISA assay and the antibody used has been designed against an epitope that is shared by at least seven isoforms of the beta-conglutin proteins of the Lupinus angustifolius species and at least one isoform of the Lupinis albus species. Thus, the method of the invention is highly specific and sensitive, so that it may detect and quantify even lupin traces present in food samples which might elicit allergic reactions in sensitized consumers.
