说明

General description

用于质量控制的经认证的药物二级标准为制药实验室和制造商提供了一种方便且具有成本效益的药典主要标准替代品。

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。

这些二级标准品是合格的认证标准物质（CRM）。它们适用于多种分析应用，包括但不限于药物释放测试、药物的定性和定量分析方法开发、食品和饮料质量控制检测以及其他校准需求。

Analysis Note

These secondary standards offer multi-traceability to the USP and EP primary standards, where they are available.

Determination of Urea in Milk by HPTLC

An HPTLC method for rapid urea detection in milk using a TLC plate scanner and Silica Gel 60 F254 HPTLC plate.

Wearable smart sensor systems integrated on soft contact lenses for wireless ocular diagnostics.

Joohee Kim et al.

Nature communications, 8, 14997-14997 (2017-04-28)

Wearable contact lenses which can monitor physiological parameters have attracted substantial interests due to the capability of direct detection of biomarkers contained in body fluids. However, previously reported contact lens sensors can only monitor a single analyte at a time.
