Proteins: are essential nutrients for the human body. They are one of the building blocks of body tissue and can also serve as a fuel source. As a fuel, proteins provide as much energy density as carbohydrates: 4 kcal per gram; in contrast, lipids provide 9 kcal per gram.

The ExpiCHO and Expi293 transient expression systems offer all-in-one solutions for generating high-titer recombinant proteins for a broad range of research applications including candidate d...
Many research laboratories use the ExpiCHO Expression System to transiently produce candidate biomolecules for biologics development. However, after the lead candidate is found, a stable cell...
摘要杆状病毒表达载体系统(BEVS)是重组蛋白生产的主要平台之一。与哺乳动物表达系统早已转换为无血清,化学成分限定的培养基不同,昆虫表达系统的创新相对较少。昆虫细胞继续依赖成分不限定的含酵母提取物的培养基,而这些培养基可以显示出明显的细胞生长和蛋白质表达的批次差异。在这里,我们介绍一种新型的Sf9细胞杆状病毒表达系统的开发。此系统包括支持高细胞密度、化学成分限定的培养基,...
HEK293和CHO细胞是快速、规模可调的悬浮培养系统中常用的细胞系,可用于瞬时蛋白表达。此次演讲介绍了瞬时表达的基本概念和使用材料,以及使用293或CHO细胞时需要考虑的主要差异。...
ExpiCHO是一种高效的瞬时表达系统,可以在2周内获得与稳定细胞株相当的表达量。 CHO细胞长期以来一直在工业界广泛使用,获得CHO表达蛋白必须构建稳定的细胞株,这一过程不仅耗时耗力,而且需要经验丰富的研发人员。在药物开发阶段需要在较短时间获得大量蛋白,往往只能采用293细胞的瞬转表达系统,但该系统产量低,表达蛋白与CHO系统存在质量差异。ExpiCHO作为高效的瞬时表达系统能...
