Stevioside has not been previously evaluated by the committee . after oral administration to rats , stevioside is not readily absorbed from the upper small intestine but is hydrolysed to the aglycone , steviol , before absorption from the gut 甜菊糖?喂食大鼠后，并不会在上小肠马上被吸收，而是先水解为配基( aglycone )甜菊醇，才被肠道吸收。
Methods receptor binding assay ( rba ) was adopted to measure the distribution of pgr and er in liver cancer and tissue in its vicinity in 63 patients with primary liver cancer ( plc ) undergone laparotomy and in non - tumor liver tissue in 7 cases with gastric carcinoma 方法采用放射性配基结合分析法( rba )测定了63例行手术切除的肝癌组织、癌周组织及7例非肝癌肝组织的雌、孕激素受体的含量并结合临床资料进行统计分析。
On account of vaccination purpose , the neutralizing protection of anti - ns5 antibodies should be tested . ( 3 ) screening antagonistic peptide of ns5 protein a library of phage - displayed disulfide - constrained random peptides was incubated with a plate coated with the recombinant ns5 protein ( 3 ) nss蛋白小分子结合肤的筛选:以活性表达的nss蛋白为配基，从噬菌体展示的构象约束性随机肤库中筛选相应的配体分子，共进行了4轮筛选。
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 报道了由正负离子表面活性剂与高聚物混合溶液形成的一种可用于蛋白质的分离及分析的新型双水相萃取体系.研究了正负离子表面活性剂(溴化十二烷基三乙铵/十二烷基硫酸钠)分别与葡聚糖和聚乙二醇混合双水相体系的形成规律、相行为及牛血清蛋白和溶菌酶在双水相体系中的分配.通过在高聚物分子中接上亲和配基，研究蛋白质在双水相体系中的亲和分配.结果表明，在该体系中，表面活性剂与高聚物分别富集于不同相中.升高温度及加入无机盐均可促进双水相体系的形成，不同蛋白质可分配于不同的相中.亲和配基的引入极大地增强了蛋白质分配的选择性
By applying the th model theory to analyzing the cases of developed countries that mentioned in chapter 4 , chapter 6 finds out the block gene and tendon compages that consists of the university - government - industry th . furthermore , it gives the pheno - types as some external expressions of the genotypes and the family - tree diagram constituted by these phenotypes . after a transition , it illuminates the scientometric , the webometric and the triple helix algorithm and their application 第六章运用th模型理论对第四章提供的案例挖掘梳理后，发现并给出了：构成大学?政府?产业三重螺旋体的完整板块配基和键链组合，作为“基因型”外在表达的一些“现象型”属类以及由它们所构成的图式谱系。
Udp - glucuronosyltransferases ( ugts ) are glycoproteins localized in the endoplasmic reticulum that catalyze the conjugation of a broad variety of endogenous and exogenous lipophilic aglycon substrates ( such as bilirubin , steroid hormone and drugs , insecticide , etc ) with glucuronic acid using udp - glucuronic acid ( udpga ) as the sugar donor . ugts are a gene superfamily of phase ii drug - metabolizing enzymes , they are responsible for the glucuronidation of a significant number of different functional groups ( e . g Ugts能催化各种各样外源和内源的亲脂性糖苷配基底物与葡醛酸的结合，该反应是机体清除外源性(如药物和杀虫剂)和内源性(如胆红素和甾体激素)亲脂性化合物的一个主要方式，也是药物相代谢的重要方式。
These phage display peptides may be the tnfa mimotopes . part iii specific c7c tnfa mimotope phage clone as target for screening of tnfa specific binding - peptides from 12mer phage display peptide library : by using the specific c7c tnfa mimotope as target , we developed a novel approach for screening phage peptide library targeting specific phage display peptides . we used c7c tnfa mimotope phage clone lcs - 7 ( c - rrpaqsg - c ) as target to screen 12mer phage peptide library and identify the positive clones by phage elisa 3 、以特异性噬菌体克隆为靶筛选肽库的研究? ?一种肽库筛选新方法的建立：为了深入研究细胞因于与配基（受体或抗体）相互作用的关键残基及其空间构象，在上述研究基础上，我们以tnfa表位模拟肽克隆为靶筛选噬菌体十二肽库，找寻与之结合的tnfa结合肽噬菌体克隆；并以此拓宽了噬菌体肽库的应用范围。
