蛋白质修饰——PEG修饰服务蛋白质药物用于人类疾病的治疗近几年得到飞速发展，但蛋白质药物却存在诸如半衰期短、高免疫原性、低溶解性、易被酶水解等弊端。用PEG（聚乙二醇）修饰这些蛋白质分子，能明显消除这些不利因素，成为延长蛋白质半衰期，改变其药代动力学特性与免疫原性的有效手段。可以用于PEG修饰的目标蛋白质包括重组蛋白质、合成的肽段、抗体片段等。蛋白质修饰（PEG修饰）具有广阔的应用前景，迄今为止，已经有十个PEG修饰的蛋白质药物通过美国FDA批准上市。有效的进行蛋白质修饰/PEG修饰的关键步骤包括：一、选择合适的PEG分子以获得较好的药代动力学特性。二、选择可靠的供应商以保障原料来源的品质及稳定性。三、选择恰当的反应基团以保障修饰位点的特异性从而最大限度的保持药物的生物学活性。四、选择最佳的修饰条件如缓冲液体系、pH、时间等，以保障尽量高的修饰率与活性保留比例、降低原料成本。五、建立合理的分离工艺，去除未修饰蛋白的残留。由于PEG修饰总是会导致蛋白质活性的下降，高活性的痕量未修饰蛋白会严重干扰修饰后样品的活性，并导致用药时的困难。·蛋白质修饰可提供服务：一、PEG选择：评价PEG是否合适的标准包括药代动力学参数、目标蛋白活性保留程度、免疫原性、修饰效率、可放大性与成本等。二、PEG修饰蛋白质制备：在完成PEG选择步骤后，欣百诺可以为您进行工艺放大并制备您需要的PEG修饰蛋白。我们可以提供毫克到克级的修饰蛋白。我们也可以提供符合中国GLP/GMP标准的大规模样品生产，供您临床前研究与临床研究。三、中试/大规模PEG修饰过程开发：欣百诺的过程开发服务可以为您提供工业规模的PEG修饰工艺，并按照药品要求建立修饰后的目标蛋白质纯化工艺。所建立的技术工艺与相关知识产权可以归客户所有。上海西宝生物科技有限公司杨露（6221）13512172575QQ:1916572322俞婵（6512）13817370083QQ:2457655304杨树彦（6236）13788987962QQ:1961275959电话：021-50272975/76/77/78传真：021-50272982E-mail:trade@lifesci9@MSN:lifesci9@Http://地址：上海市张江高科技园区毕升路299弄11#502【修饰性PEG】修饰性PEG又叫修饰性聚乙二醇，是经过化学修饰基团或者生物活性基团修饰的PEG。在药物开发研究中，为了增加蛋白或多肽药物在体内半衰期，降低免疫原性，同时增加药物的水溶性，使用有化学基团修饰的PEG与蛋白药物共价结合，与蛋白结合之前的带有修饰性基团的PEG就是修饰性PEG。【修饰性PEG的修饰基团】：氨基（-Amine）-NH2，氨甲基-CH2-NH2，马来酰亚胺-Mal，羧基-COOH,巯基（-Thiol）-SH，丙醛-ALD，琥珀酰亚胺碳酸酯-SC，琥珀酰亚胺乙酸酯-SCM，琥珀酰亚胺丙酸酯-SPA，琥珀酰亚胺琥珀酸酯-SS，琥珀酰亚胺-NHS，二硫吡啶基-OPSS，丙酸基-CH2CH2COOH，醛基-CHO，正吡啶二硫基-S-S-Pyridine，巯酯基-VS，丙烯酸基-Acrylate，丙烯酸基-AC，叠氮基-Azide，生物素基-Biotin，环氧基-EP，荧光素基-Fluorescein，戊二酸基-GA，酰肼基-Hydrazide，炔基-Alkyne，对硝基苯碳酸酯基-NPC，异氰酸基-NCO，邻二硫吡啶基-OPSS，硅烷基-Silane，-SVA，BOC-，羧甲基-CM，Fmoc-NH-。张江高科技园区杨露13512172575。上海Seebio代理LaysanBio、CreativePEGWorks、IrisBiotechCfm、NOF日油等不同规格的修饰性PEG，进口原装，1～2周货期，可供应mg-kg级别的修饰性PEG。【常用的修饰性PEG】Seebio货号货号品名包装LP-0014arm-PEG-ACRL-10K-1g4arm-PEG-ACRL,MW10kDa1gLP-0024arm-PEG-ACRL-20K-1g4arm-PEG-ACRL,MW20kDa1gLP-0034arm-PEG-ACRL-20K-5g4arm-PEG-ACRL,MW20kDa5gLP-0044arm-PEG-CM-10K-1g4arm-PEG-CM,MW10kDa1gLP-0054arm-PEG-CM-10K-5g4arm-PEG-CM,MW10kDa5gLP-0064arm-PEG-EPOX-10K-5g4arm-PEG-Epoxide,MW10kDa5gLP-0074arm-PEG-EPOX-20K-1g4arm-PEG-Epoxide,MW20kDa1gLP-0074arm-PEG-EPOX-20K-5g4arm-PEG-Epoxide,MW20kDa5gLP-0084arm-PEG-MAL-10K-1g4arm-PEG-MAL,MW10kDa1gLP-0094arm-PEG-MAL-20K-1g4arm-PEG-MAL,MW20kDa1gLP-0104arm-PEG-NH2-10K-1g4arm-PEG-NH2,MW10kDa1gLP-0104arm-PEG-NH2-10K-5g4arm-PEG-NH2,MW10kDa5gLP-0114arm-PEG-NH2-20K-1g4arm-PEG-NH2,MW20kDa1gLP-0114arm-PEG-NH2-20K-5g4arm-PEG-NH2,MW20kDa5gLP-0124arm-PEG-SCM-10K-1g4arm-PEG-SCM,MW10kDa1gLP-0124arm-PEG-SCM-10K-5g4arm-PEG-SCM,MW10kDa5gLP-0134arm-PEG-SH-10K-1g4arm-PEG-Thiol,MW10kDa1gLP-014ACRL-PEG-ACRL-1000-1gAcrylate-PEG-Acrylate,MW1,0001gLP-015ACRL-PEG-ACRL-10K-1gAcrylate-PEG-Acrylate,MW10kDa1gLP-016ACRL-PEG-ACRL-2000-1gAcrylate-PEG-Acrylate,MW2,0001gLP-017ACRL-PEG-ACRL-20K-1gAcrylate-PEG-Acrylate,MW20kDa1gLP-018ACRL-PEG-ACRL-3400-1gAcrylate-PEG-Acrylate,MW3,4001gLP-018ACRL-PEG-ACRL-3400-5gAcrylate-PEG-Acrylate,MW3,4005gLP-019ACRL-PEG-ACRL-5000-1gAcrylate-PEG-Acrylate,MW5,0001gLP-019ACRL-PEG-ACRL-5000-5gAcrylate-PEG-Acrylate,MW5,0005gLP-020ACRL-PEG-MAL-3400-1gAcrylate-PEG-Maleimide,MW3,4001gLP-021ACRL-PEG-SCM-2000-1gAcrylate-PEG-SCM,MW2,0001gLP-021ACRL-PEG-SCM-2000-500mgAcrylate-PEG-SCM,MW2,000500mgLP-022ACRL-PEG-SCM-3400-1gAcrylate-PEG-SCM,MW3,4001gLP-022ACRL-PEG-SCM-3400-500mgAcrylate-PEG-SCM,MW3,400500mgLP-023ACRL-PEG-SCM-5000-1gAcrylate-PEG-SCM,MW5,0001gLP-024ACRL-PEG-SVA-3400-1gAcrylate-PEG-SVA,MW3,4001gLP-024ACRL-PEG-SVA-3400-500mgAcrylate-PEG-SVA,MW3,400500mgLP-025bALD-PEG-bALD-10K-1gButyrAldehyde-PEG-ButyrAldehyde,MW10kDa1gLP-025bALD-PEG-bALD-10K-5gButyrAldehyde-PEG-ButyrAldehyde,MW10kDa5gLP-026bALD-PEG-bALD-20K-1gButyrAldehyde-PEG-ButyrAldehyde,MW20kDa1gLP-026bALD-PEG-bALD-20K-5gButyrAldehyde-PEG-ButyrAldehyde,MW20kDa5gLP-027bALD-PEG-bALD-3400-1gButyrAldehyde-PEG-ButyrAldehyde,MW3,4001gLP-027bALD-PEG-bALD-3400-5gButyrAldehyde-PEG-ButyrAldehyde,MW3,4005gLP-028bALD-PEG-bALD-5K-1gButyrAldehyde-PEG-ButyrAldehyde,MW5,0001gLP-028bALD-PEG-bALD-5K-5gButyrAldehyde-PEG-ButyrAldehyde,MW5,0005gLP-029Biotin-PEG-MAL-3400-100mgBiotin-PEG-Maleimide,MW3,400100mgLP-029Biotin-PEG-MAL-3400-1gBiotin-PEG-Maleimide,MW3,4001gLP-029Biotin-PEG-MAL-3400-500mgBiotin-PEG-Maleimide,MW3,400500mgLP-030Biotin-PEG-MAL-5000-1gBiotin-PEG-Maleimide,MW5,0001gLP-031Biotin-PEG-NH2-2000-500mgBiotin-PEG-NH2,MW2,000500mgLP-032Biotin-PEG-NH2-3400-100mgBiotin-PEG-NH2,MW3,400100mgLP-032Biotin-PEG-NH2-3400-1gBiotin-PEG-NH2,MW3,4001gLP-033Biotin-PEG-NH2-5000-100mgBiotin-PEG-NH2,MW5,000100mgLP-033Biotin-PEG-NH2-5000-1gBiotin-PEG-NH2,MW5,0001gLP-034Biotin-PEG-SC-2000-100mgBiotin-PEG-SC,MW2,000100mgLP-034Biotin-PEG-SC-2000-1gBiotin-PEG-SC,MW2,0001gLP-035Biotin-PEG-SC-3400-100mgBiotin-PEG-SC,MW3,400100mgLP-035Biotin-PEG-SC-3400-1gBiotin-PEG-SC,MW3,4001gLP-035Biotin-PEG-SC-3400-500mgBiotin-PEG-SC,MW3,400500mgLP-036Biotin-PEG-SC-5000-100mgBiotin-PEG-SC,MW5,000100mgLP-037Biotin-PEG-SCM-3400-100mgBiotin-PEG-SCM,MW3,400100mgLP-037Biotin-PEG-SCM-3400-1gBiotin-PEG-SCM,MW3,4001gLP-037Biotin-PEG-SCM-3400-500mgBiotin-PEG-SCM,MW3,400500mgLP-038Biotin-PEG-SCM-5000-100mgBiotin-PEG-SCM,MW5,000100mgLP-038Biotin-PEG-SCM-5000-1gBiotin-PEG-SCM,MW5
