Testing for Hyperhomocysteinemia in Subjects with a History of Thromboembolic Events Using HPLC Technique

to derivate with plasma homocysteine after release of the amino acid from homo- and heterodimers and protein bond using TBP. Separation is performed using a c18 reverse-phase column with aqua and acetonitrile as solvent. Due to continuous release

residue was substituted with its synthetic polyamino derivate. The substitution provided indolicidin analog with increase net positive charge, more ordered secondary structure in biological membranes mimicking conditions, and enhanced antibacterial

蛋白分离的不连续缓冲系统的比较

在电泳开始的时候，SDS-PAGE 利用不连续系统，在浓缩胶中浓缩或"堆积"样品，使其成为一条非常锐利的区带。在不连续缓冲系统中，最初胶中的阴离子不同于（或不连续）电泳缓冲液中开始时的阴离子。NuPAGE系统（Bis-Tris和Tris-Acetate）和Laemmli(Tris-Glycine)系统二者均为不连续系统的例证，以相同的方式起作用。但是，作为NuPAGE系统中不同离子的结果，这个系统在一个较低的pH值下工作。Tris-Glycine系统（图1）的情况，主要包括三种离子： a)氯
