应用
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.
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。
特点和优势
Available with a certificate documentingnitrogen value determined through a modification of the AOAC micro-Kjeldahlmethod.
