General description
Application
用于蛋白质变性以及作为不溶性或变性蛋白的温和增溶剂。可用于从已由 6M 盐酸胍变性的样品(如包涵体)复性蛋白质。可与盐酸胍和二硫苏糖醇 (DTT) 一起用于复性变性蛋白以恢复其天然或活性形式。
Urea Standard reference material (SRM) is certified for calibrating and standardizing microchemical procedures aimed at determining nitrogen in organic matter. Additionally, it serves as a tool for standardizing techniques for nitrogen determination, when carbon and hydrogen are simultaneously analyzed.
Features and Benefits
Available with a certificate documentingnitrogen value determined through a modification of the AOAC micro-Kjeldahlmethod.
