2. 与PEI 25相比,PEI MAX 40K连续性提供更高滴度【见Fig 1】:PEI 25含4-11%残留的丙酰基基团,该基团阻止聚合物骨架紧密结合到DNA。然而,PEI MAX 40K完全去丙酰化,意味着每个批次一贯具更高转化效率。Method: 10e6/mL HEK293 cells in 50 mL FS transfected with IgG64 plasmid pair. PEI:DNA 4:1. Samples taken 120 hpt. Quantified with Thermo Fisher #23310. N=4 each. Error bar = standard deviation. 【好消息】:针对小量用户或初次使用用户,现针对24765-1g,提供250mg小包装,目录价1100元;欢迎来电咨询具体价格。应用文献【基因转染用途】:Mann JF, McKay PF, Arokiasamy S, Patel RK, Klein K, Shattock RJ. (2013).
