| 3. | Usually , the hpv virus through is attaching has the chemical reaction to the cell surface and with these cell surface proteins to be able to attack the cell
通常， hpv病毒通过附着到细胞表面并与这些细胞表面蛋白发生化学反应得以攻击细胞。 |
| 4. | Researchers removed tumors after they grew , and then sorted millions of cancer cells to isolate those that had one or more of three surface protein markers - - cd44 , cd24 , and esa
肿瘤生长后切除肿瘤，并且从数以百万计的癌细胞中筛选出表达一个或多个表面蛋白标记物（ cd44 、 cd24和esa ）的细胞。 |
| 5. | Like the trypanosome ' s vsg coat , the immune system ' s b lymphocytes also express one protein ( immunoglobulin ) on their surface at a time , even though each b cell has many different genes for the surface proteins
一如锥虫的vsg外套，人体免疫系统的b淋巴球就算拥有许多不同表面蛋白的基因，每回也只表现一种表面蛋白（免疫球蛋白） 。 |
| 6. | Conclusion : a 496 bp fragment of the gene encoding t gondii p22 surface protein was successfully cloned into the plasmid pthiohisa , b , c and expressed in the e . coli top 10 , and the fusion proteins can be purificated effectively
结论：成功构建弓形虫zs株表膜抗原p22编码是因pthiohisa ， b ， c p22表达质粒，诱导表达弓形虫农牧抗原p22蛋白，儿g 。 |
| 7. | Es cells and their derivatives carry the same likelihood of immune rejection as a transplanted organ because , like all cells , they carry the surface proteins , or antigens , by which the immune system recognizes invaders
胚胎干细胞以及它们所衍生出的细胞，和移植的器官一样，在细胞表面都带有蛋白质（抗原） ，会让免疫系统视为入侵者，而产生免疫排斥作用。 |
| 8. | Seven - span transmembrane ( 7 - tm ) molecules constitute superfamilies of cell - surface proteins . they are receptors for small molecules . peptides , hormones and ions . they also act as ligands for mediating a variety of external signals to the cytoplasm
它们主要作为一些小分子物质如肽类，激素，细胞因子和多种离子的受体，主要功能是介导细胞外信号传递和调节细胞的生物学功能。 |
| 9. | The env protein deduced from env gene encodes the hydrophilic surface protein ( su ) and the hydrophobic transmembrane domain ( tm ) that determine the specific interaction between virus particles and cell surface receptors during retroviral entry . the su of retroviruses is a highly variable genetic element , containing receptor binding sites and major antigenic determinants . exjsrv - specific dna probes were derived . by using these dna probes in tissue hybridization . we successfully identified jsrv mrna expression and proviruses dna in sheep lung tissues infected with jsrv and control group has no postive signals , validating the use of exogenous virus - specific dna probes in the analysis of oncogenic proviral integration sites and identification of integrated exogenous proviral sequences
用地高辛随机引物法标记exjsrv特异的env片段，制备探针，原位杂交检测spa肺组织中的rna及前病毒dna ，结果表明spa患羊肺组织内有jsrvenv基因mrna的表达，同时也检测到了前病毒dna ，而相应的阴性对照却无阳性信号，证实外源性病毒特异的dna探针在致瘤性前病毒的整合位点和整合的外源性前病毒的检测中具有可信度。 |
| 10. | After bacterium cells were treated by formaldehyde , surface proteins of gram - negative bacterium e . coli k12 were eluted little , but it had no influence on adsorption of snake venom proteins to bacterium cells . treatment by formaldehyde had little influence on snake venom absorption to and deabsorption from gram - positive bacterium streptococcus mutans , but absorbance of interaction protein with molecular weight of 47kda only adsorbed by streptococcus aureus was greatly decreased
结果表明，灭活后的革兰氏阴性菌( e . colik12 )再与蛇毒相互作用时，洗脱下来的蛋白中菌体蛋白含量明显减少，但不影响对作用蛋白的吸附；甲醛灭活对革兰氏阳性菌( s . mutans和s . aureus )影响不大，只有s . aureus吸附蛋白中47kda的蛋白吸附量减少，不会影响作用蛋白中其它蛋白的吸附。 |
