离心法

在自动化工作流程中促进液体提取和蛋白质沉淀

离心是许多样品制备工作流程中至关重要的一步。分析离心用于有效沉淀表面、废水或污泥等样品中的沉淀物。它还用于液/液萃取（LLE，DLLME）后的两相分离，或变性后的蛋白质沉淀。离心作用极大地简化了很多样品制备的应用。
PAL离心机结构紧凑，不占用工作台空间，也完全集成到了方便的PAL Method Composer软件可快速创建自动化工作流程脚本。

PAL离心机

  • 空气制冷的PAL离心机经过唯一认证，可用于操作易燃液体，如经常使用的有机化合物溶剂、酒精或醚类，装在带帽的小瓶中。

  • PAL离心机可以有效地集成在许多工作流程中。省略了繁琐且容易出错的离线步骤。可提供2mL、10mL、20mL的转子或与高达5000g的相对离心力（RCF）组合的转子

  • 将当前离心机的转速（每分钟转数）转换为重力值（g force）。没有半径信息的离心机规格（rpm）是没有意义的，也无法进行比较。对于已知的离心机，从以厘米为单位的半径和以转/分为单位的速度，g force的转换是用以下公式计算的：
    g force (RCF) = 1.118.  10-5. r .rpm2
    RCF:相对离心力，以g的倍数表示
    r:从中心到小瓶底部的转子半径[cm]
    rpm:转速，单位为每分钟转数[min-1

A single-sample workflow for joint metabolomic and proteomic analysis ofclinical specimens

Integrating proteomic and metabolomic data enhances ourunderstanding of biological processes and diseasemechanisms. Traditional multi-omics workflows often requireseparate sample processing, leading to increased variability.To address this, we developed MTBE-SP3, an optimizedsingle-sample workflow that combines a 75% EtOH/MTBEmetabolite extraction with automated single-pot solid-phase-enhanced sample preparation for proteins.
