dextrin

There are so many molecules involved the fertility , such as : spl7 , a mammalian testis - and sperm - specific protein , can specifically bind with zona pellucida , dextran , dextran sulfated , and fucoidin . another germ cell cyritestin is a testis - and sperm - specific protein belonging to the adam family . it has a disintegrin domain at the n - terminal , known as a integrin ligand , that suggests cyritestin could be involved in sperm adhesion and fusion with the egg membrane previous study demonstration 配子中的許多分子均參與了上述關鍵環節,如在精母細胞、精細胞和睪丸精子中表達,并特異性與卵子透明帶糖蛋白、葡聚糖、糖酐脂結合的精子表面蛋白17 ( sp17 ) ,以及參與識別或與卵子膜上的整合素相互作用的adam家族成員之一的cyritestin蛋白等。

A novel aqueous two - phase system can be formed by the mixtures of a polymer and cationicanionic surfactants . such a system can be used as a partitioning system of proteins . in this work , we investigated the formation , phase behavior and protein partitioning in aqueous two - phase systems formed by dodecyltriethylammonium bromide / sodium dodecylsulfate / peg and dodecyltriethylammonium bromide / sodium dodecylsulfate / dextran . the ligands with affinity were attached to the polymers and the affinity partitioning of proteins was investigated . it was shown that the surfactants and polymers are enriched in different phases of aqueous two - phase systems . phase separation are promoted by increasing temperature and adding inorganic salts . different proteins are partitioned in different phases . the selectivity of protein partitioning is increased by adding ligands with affinity 報道了由正負離子表面活性劑與高聚物混合溶液形成的一種可用于蛋白質的分離及分析的新型雙水相萃取體系.研究了正負離子表面活性劑(溴化十二烷基三乙銨/十二烷基硫酸鈉)分別與葡聚糖和聚乙二醇混合雙水相體系的形成規律、相行為及牛血清蛋白和溶菌酶在雙水相體系中的分配.通過在高聚物分子中接上親和配基,研究蛋白質在雙水相體系中的親和分配.結果表明,在該體系中,表面活性劑與高聚物分別富集于不同相中.升高溫度及加入無機鹽均可促進雙水相體系的形成,不同蛋白質可分配于不同的相中.親和配基的引入極大地增強了蛋白質分配的選擇性
