方法分別採用苯酚硫酸法、剛果紅法、雙酶法和改良雙酶法測定-葡聚糖含量，並比較結果。The effect of - galactosidase and polygalacturonase on peach ripening and softening
半乳糖苷酶及多聚半乳糖醛酸酶對桃果實成熟軟化的影響Besides, vgb gene expression also increased the chitinase secretion. in order to make the vitreoscilla hemoglobin gene express in bacillus subtilis, an inducible promoter ( levansucrase ) was cloned from b. subtilis wb600 and ligated with a promoter - less vgb gene. the resulted gene is called sacvgb and was demonstrated to express in e, coli by sds - page and carbon monoxide binding assay
由於vgb基因啟動子不能在枯草桿菌中啟動表達，因此，根據已發表的果聚糖蔗糖酶基因（ sacb ）序列設計引物，從枯草桿菌wb600總dna中擴增出該基因的啟動子片段，然後將其與vgb基因編碼區及終止子序列相連，成功地組建了sacvgb融合基因。Fos contain mixture of gf2, gf3 and gf4 sugars ( where g = glucose molecule and f = fructose molecule ) and a dp ( “ degree of polymerization ” ) of 3 - 5 ( “ neosugar ” ), are not naturally - occurring but are enzymatically synthetized from sucrose by action of an enzyme from the fungus aspergillus niger
詳細說明：是以蔗糖做底物，採用呋喃果糖苷酶轉果糖基作用，在蔗糖分子上以（ 1 2 ）糖苷鍵上與1 - 3個果糖分子結合，形成的蔗果三糖（ gf2 ） 、蔗果四糖（ gf3 ） 、蔗果五糖（ gf4 ）屬于果糖和蔗糖構成的直鏈雜低聚糖，在形成的產物中還有果糖、葡萄糖和未反應完全的底物蔗糖，採用色譜法除去單糖和雙糖制得高純度的低聚果糖。When the hameoly - mph were pretreated with activators such as sds, trypsin and zymosan, their po acti - vities increased significantly, reaching about twice of the untreated. this indicated that the po activities exist in the hameolymoh of penaeus chinensis and penaeus
結果表明，中國對蝦和南美白對蝦血清中都存在po ，主要以酚氧化酶原（ propo ）的形式存在，並且都可以被胰蛋白酶、 sds和酵母聚糖激活。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於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於不同相中.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By using the polyacrylamide gel electrophoresis, thirteen isozymes ( est, sod, gd, gpi, mdh, me, cat et al., ) from five population of r. philippinarum in the north of china were analised and compared
