详细介绍
PEI1000-1000沙伯基础(原GE)---海外PEI主要是通用电气电气公司生产加工。现阶段发展趋向取决于提升耐温性,为提升PEI冲击韧性,而选用PC、PA等橡胶制品构成铝合金。汇聚加工工艺层面已经开发设计单螺杆持续挤压缩聚反应技术性,预估没多久可能完成工业生产。PEI是近些年国际性上发布了一些正离子高聚物遗传基因转染技术性,以其可用寄主覆盖面广,实际操作简单,对细胞毒性小,转染高效率遭受学者们的亲睐。PEI是十分有期待的基因疗法媒介。现阶段在设计方案更繁杂的遗传基因媒介时,PEI常常作为关键构成成份。线形PEI(LinePEI,LPEI)两者之间化合物作为遗传基因转染媒介的科学研究比发枝状PEI(BranchedPEI,BPEI)要早一些,以往的科学研究觉得在没有考虑到条件,LPEI/DNA转染一氧化氮合酶的细胞毒性较低,有益于体细胞精zhun定位,与BPEI对比应当转染高效率一些。但近期研究表明BPEI的发枝度提高有益于产生小的转染一氧化氮合酶,进而提升转染高效率,但细胞毒性也扩大。极高发枝的、较软性的PEI化合物带有附加的仲胺基和叔胺基,在染试验中发觉这类PEI的毒副作用低,但转染高效率却较高
Overseas Pei is mainly produced and processed by GeneralElectric Company. At present, the development trend depends onimproving the temperature resistance. In order to improve theimpact toughness of Pei, PC, PA and other rubber products are usedto form aluminum alloy. The technology of single screw continuousextrusion polycondensation has been developed and designed at thelevel of convergence processing technology. It is estimated thatthe industrial production will be completed soon. Pei is a kind ofpositive ion polymer gene transfection technology which has beenreleased internationally in recent years. It is favored by scholarsfor its wide host coverage, simple operation, low cytotoxicity andhigh transfection efficiency. Pei is a promising vector for genetherapy. Pei is often used as a key component in the design of morecomplex genetic vectors. The research on the compound betweenlinear Pei (lpei) and branched Pei (bpei) as genetic genetransfection medium is earlier than that of branched Pei (bpei).Previous scientific research found that the cytotoxicity of lpei /DNA transfection of nitric oxide synthase is lower withoutconsidering the conditions, which is beneficial to the preciselocalization of somatic cells. Therefore, compared with bpei, lpei/ DNA transfection should be more efficient. However, recentstudies have shown that the increase of branching degree of bpei isbeneficial to the production of small transfected nitric oxidesynthase, thus improving the transfection efficiency, but inaddition, the cytotoxicity is also expanded. The high branched andsoft Pei compounds have additional secondary and tertiary aminegroups. In the staining test, it was found that the toxic and sideeffects of Pei were low, but the transfection efficiency washigh
