Electrophoresis Buffers

電気泳動用緩衝液は、DNA、RNA、およびその他のタンパク質の分離中に一定のpHレベルを維持します。印加された電流を伝達するイオンを供給することで、低電荷の溶液はさまざまな分子サイズが異なる速度で移動し、分析が可能となります。タンパク質を追加で保護する調製用物質は分解を防ぎ、サンプルの生存性と正確な試験結果を保証します。さまざまな分子量で入手可能で、取り扱う特定の高分子に基づいて最適な電気泳動緩衝液を選択できます。

MOPS10Xバッファー、バイオテクノロジー用

Supplier: VWR Chemicals

MOPS is a zwitterionic buffer used as a running buffer for denaturing agarose gel electrophoresis of RNA. Having a pH buffering range from 6,5 to 7,9, MOPS works exceptionally well with formaldehyde gels at 20 mM concentration.
