产品介绍
阿拉丁生产的PAGE上层胶红色染料(500X, 无迁移) (Red Dye for PAGE Stacking Gel, 500X, without Migration)是一种用于配制红色聚丙烯酰胺上层凝胶的染料,该红色染料可使蛋白上样孔一目了然,便于上样,而且易于判断上样孔是否歪曲或破损。本染料不会随着电泳而迁移。本红色染料可以稳定存在于上层胶(又称浓缩胶、堆积胶或积层胶)中,不会随着电泳进入分离胶,不会影响电泳和染色效果,电泳后很方便辨别上层胶并进行切除,便于分离胶的转膜等实验。使用本红色染料配胶及电泳后的效果参考图1。图1. PAGE上层胶红色染料(500X, 无迁移)用于PAGE上层胶配制和电泳的效果图。左图为使用PAGE上层胶红色染料(500X, 无迁移)配制的上层胶被染成红色,上样孔一目了然,易于判断上样孔是否歪曲或破损;中间图是上样后的效果图,上层胶和样品非常清晰;右图为阿拉丁四种彩色预染蛋白分子量标准P0078、P0075、P0071、P0068电泳后的效果,染料保留在上层胶中,不会随着电泳而迁移,也不影响电泳效果。本图仅作参考。对于1.0mm厚凝胶,每块凝胶约需配制2ml上层胶,按照每1ml上层胶加入2μl PAGE上层胶红色染料(500X, 无迁移),此时本红色染料每1ml约可用于250块凝胶的配制。4℃保存,一年有效。 使用说明 : 1.使用前将本染料适当上下颠倒混匀。2.根据需要配制适量上层胶,按照每1ml上层胶加入2μl PAGE上层胶红色染料(500X, 无迁移)的比例加入染料,适当混匀。3.加入上层胶凝胶聚合催化剂(如过硫酸铵或其它过硫酸铵替代物)和TEMED,充分混匀后即可用移液管或加样枪将上层胶注入制胶玻璃板之间直至与短玻璃板平齐,并插入电泳梳。4.上层胶凝固后,拔去电泳梳即可用于电泳。具体的配胶步骤可参考阿拉丁的SDS-PAGE凝胶配制试剂盒、SDS-PAGE凝胶快速配制试剂盒、MiniProGel™蛋白制胶与电泳系统等产品说明书。5.详细的Western操作可以参考我们的相关网页:http://www.aladdin-e.com/support/western.htm。
