4-吗啉乙磺酸钠盐(MES)因其优异的性能而成为科研中常用的两性离子缓冲剂。它可以在pH 5.5-6.5范围内有效缓冲溶液,pKa值为6.1。该产品已通过 BioPerformance 认证,作为缓冲剂广泛应用于生物化学和分子生物学实验中,有助于稳定蛋白质印迹、细胞培养和电泳等不同生物反应中的 pH 值。MES是为生物学应用开发的所谓的“良好”缓冲液之一。 使用MES游离酸的缓冲液可通过使用氢氧化钠对游离酸进行滴定至所需的pH(pKa=±1)而进行制备。或者,可以将一定体积的MES游离酸和MES钠等摩尔溶液混合以达到所需的pH值。已经公布了使用储备溶液来制备给定pH值的缓冲液的标准混合布。
4-Morpholineethanesulfonic acid, sodium salt (MES) is a popular zwitterionic buffer in scientific research due to its excellent properties. It can buffer solutions effectively within a pH range of 5.5-6.5 with a pKa value of 6.1. This product is BioPerformance certified and it finds extensive application as a buffering agent in biochemistry and molecular biology experiments, contributing to the stabilization of pH in different biological reactions including western blotting, cell culture and electrophoresis.
MES is one of the so-called 'Good' buffers developed for biological applications. A buffer using MES free acid can be prepared by titrating the free acid with sodium hydroxide to the desired pH (pKa=±1). Alternatively, volumes of equimolar solutions of MES free acid and MES sodium can be mixed to attain the desired pH. Standard mixing tables using stock solutions to prepare a buffer of a given pH have been published.
Application:
MES sodium salt has been employed as a coupling buffer for amine-reactive sensors at either pH 4.5 or pH 5.0 to facilitate the coupling of monoclonal antibodies (MAbs) onto the sensors, used in hybridization studies with fluorescently-labeled complementary strands and microarray slide washing during microarray analysis, and played a role in preparing a new set of RNA phosphoramidites compatible with in situ photolithography for growing RNA oligonucleotides on microarrays.
MES sodium salt has been used as a coupling buffer during the coupling of MAbs onto amine-reactive sensors. It has also been used as a component of germination medium and shoot induction medium during in vitro plant regeneration.
