Introduce preparation method , process and marker trend of high viscosity carboxy methyl starch sodium , and its application in food , industry , medicine , printing and dyeing 摘要介绍了高粘度羧甲基淀粉钠的制备方法、工艺、市场前景及其在食品、工业、医药、印染等方面的应用。
The effect of carboxy methyl cellulose , high ester pectin and propy leneglucolalginate were significant , and we experienced the synergic effect of them by positive cross assay 增稠剂羧甲基纤维素钠、高酯果胶及藻酸丙二醇酯能够显著提高调酸果奶的稳定性，并通过正交试验进行增稠剂的复配。
The results showed that the acidic juice - milk could preserved stablely by adding multiple stabilizer consisted of 0 . 14 % high ester pectin , 0 . 20 % sodium carboxy methyl cellulose , 0 . 175 % propy leneglucolalginate , 0 . 12 % sodium citrate 结果表明：添加0 . 14 %高酯果胶、 0 . 20 %羧甲基纤维素钠、 0 . 175 %藻酸丙二醇酯复合增稠剂与0 . 12 %柠檬酸钠，可使调酸果奶达到良好的稳定效果。
These results support the biocompatibility of cnx and dlc and should initiate an interesting to the biomedical applications of cnx coating . another work of this thesis is the surface modification of polypropylene by carboxy ion ( coott ) implantation 两种不同n含量的cn膜无论是硬度、拉伸强度，还是内应力，其数值都略高于dlc薄膜，原因可能是其sp ~ 3c结构占据更多的比例。

Hegf gene with his - tag at the end , which was derived from pet22 - egf , was in - frame fused to the carboxy - terminal of polyhedrin ( ph ) gene , which included the amino - terminal 116aa coding region . the polyhedrin - egf fusion gene ( named ph - egf ) was then cut out with ecorv and ecori , and was cloned between ecorv and ecori sites of pbacpak . 8 ( the result plasmid was named pbacph - egf and the ph - egf fusing gene was right under the control of ph promoter ) . the pbacph - egf structure was verified with restriction enzymes digestion and pcr 从pet22 - egf质粒中分离出末端带his - tag的egf基因，对位融合于多角体蛋白n端116个氨基酸基因序列的下游(命名为ph - egf ) ，并在两段基因间设计了凝血酶xa蛋白酶切位点，经过酶切、测序等鉴定正确后，克隆至pbacpak8中，使ph - egf融合基因置于多角体蛋白( polyhedrin ， ph )基因启动子控制之下，构建成重组转移载体pbacph - egf 。
Many glycoproteins of lower and higher eucaryotes are attached to the plasma membrane by means of a glycosylphosphatidylinositol ( gpi ) . gpi - anchored proteins are synthesized on membrane - bound ribosomes . upon translocation of the pro - protein across the endoplasmic reticulum membrane , gpi : protein transamidase ( gp1t ) recognize and removes the carboxy terminal gpi signal sequence and attaches a gpi molecule to the newly exposed carboxy terminal amino acid Gpi化前体蛋白在依附于膜的核糖体上合成，当其易位穿过内质网( er )膜后，被gpi ：蛋白质转酰胺基酶( gpit )识别， gpit在移走其羧基端gpi信号序列的同时将gpi分子连接至新生成的氨基酸位点上。
Full - length or truncated cdna was subcloned into prokaryotic expression vector pet30a and expression induced in e . coli bl21 ( de3 ) . no squalene synthase polypeptide of expected molecular mass was observed in e . coli containing the putative full - length squalene synthase cdna , however , overexpression in e . coli was achieved by truncating 30 hydrophobic amino acids at the carboxy terminus 但在含有全长的鲨烯合酶cdna的大肠杆菌中并没有观察到预期大小的鲨烯合酶表达，而c末端截短30个疏水氨基酸的鲨烯合酶可在大肠杆菌中过量表达。
