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。
