List Labs公司成立于1978年，位于美国加州硅谷，是一家专业提供各类微生物Toxin的生物技术公司。

Our company was founded in 1978 by Linda Shoer. Cholera toxin, the first product, was sought after by those doing research in signal transduction and by others using the toxin B subunit to label neurons. At that time there were no commercial suppliers of this toxin. Our company has always focused on quality bacterial toxins, which you can depend on for your research. Because toxins have been the basis for many vaccines, List Labs products have supported vaccine development. List Labs was the first to commercialize many bacterial toxins for research, including C.difficile toxins and pertussis toxin. Today, we remain uniquely focused on manufacturing, offering and supporting a wide range of bacterial products.

List Labs' heart is in the science and the discovery of innovative reagents. Our office is located in Campbell, California, in Silicon Valley. We serve the global research community with an expanding group of distributors. Years of experience translate into expertise in the production, shipment and handling of dangerous goods. If you have questions about any of our products or services, contact us.

艾美捷科技代理Polysciences品牌。

Polysciences的产品以其高质量和多样性而著称，特别是在聚乙烯亚胺（Polyethylenimine，PEI）转染试剂方面有着显著的优势。Polysciences公司成立于1961年，主要生产和经营生命科学（胶体金、不含甲醛的甲醇等）、病理学和显镜学微球和粒子、磁珠、各种单体和聚体等产品；作为世界上最大最全的多聚化合物供应商，同时也是世界领先的免疫学、组织化学试剂耗材供应商。

Polysciences特色的PEI转染试剂特点包括：

（1）高效性：PEI转染试剂具有高效的瞬转效率和蛋白产量，广泛应用于基因和细胞治疗产品的开发，包括病毒载体和蛋白质工艺开发、临床试验以及商业化生产。

（2）广泛适用性：适用于多种细胞系，如HEK293、CHO、Sf9等，且转染效率高达80%~90%。

（3）升级产品：如PEI MAX 40K，作为第一代PEI 25K的升级产品，其去乙酰化和盐酸盐形式增强了水溶性，提高了转染效率。

产品应用范围包括：

病毒载体开发：可用于生产和优化病毒载体，将基因修饰的病毒载体导入目标细胞内，从而实现基因转染；

重组蛋白表达：可以将编码目标蛋白的基因高效地转入宿主细胞，从而大量表达所需的重组蛋白；

基因编辑技术：如CRISPR-Cas9系统中，PEI转染试剂用于将相关基因编辑组件送入细胞内；

细胞治疗研究：用于提高细胞的治疗效果和生存率，需要将特定的遗传物质传递到细胞内，以改变细胞的行为或增强其治疗效果。
