Application

本产品被指定为分子生物学级,适用于聚丙烯酰胺凝胶电泳(PAGE)。经过分析,不含核酸酶和蛋白酶。
TEMED 是一种叔胺,用于催化过硫酸铵或核黄素形成自由基。TEMED 产生的自由基导致化合物丙烯酰胺和双丙烯酰胺聚合,并形成凝胶基质聚丙烯酰胺。因为 TEMED 仅以其游离碱形式起作用,所以低 pH 条件将抑制聚合。,,
已经研究了 TEMED对银染 SDS PAGE 中背景升高的潜在作用。 TEMED 已经用于在毛细管中涂覆软聚合物(例如聚丙烯酰胺),用于通过原子力显微镜研究。 使用 TEMED 制备含有固定在凝胶垫内的寡核苷酸和蛋白质的微芯片。
通过使用 TEMED 研究了蛋白质的毛细管等电聚焦(等电点(pI)> 12)。 TEMED 已用于小有机分子的 HPLC。

Preparation Note

针对 50mL 丙烯酰胺凝胶溶液,建议用量为 35μL。
