发现更多的生物标志物
With higher confidence
代谢®uses a unified workflow to process non-targeted analyses from Bruker's ESI & MALDI Imaging instruments, simplifying the number of steps and rapidly pinpointing and identifying biomarkers.
代谢®可以跨应用领域使用,包括发现代谢组学,脂肪组学,现象学,食品,环境和制药,并为用户提供支持从基本ID到高级统计数据等工作流的灵活性。
非目标分析的目的是识别特定生理状态或样本特征的特征。由于没有单个工作流程可以访问所有化合物的动态时间和空间指纹,因此需要评估互补平台的数据。代谢®通过允许评估ESI和MALDI成像的互补数据,并在其生物学背景下自信分配相关标记来解决这些需求。
通过集成工具(例如基于精确的前体和片段质量(smartformula3d),搜索本地和公共数据库(CompoundCrawler),诸如分子公式的确定(CompundCrawler),可以通过集成工具确定识别未知化合物的识别,例如在硅中fragmentation to match theoretical to measured MS/MS (MetFrag) and MS/MS bucket matching for the identification of chemically related compounds.
Unknown ID pipeline:
A) SmartFormula3D limits possible precursor molecular formulea to typically one or a few candidates by automatically matching accurate mass and isotopic pattern fragment and precursor ion information.
b)本地和公共数据库中候选公式的查询返回可能的候选结构。
C)In silicofragmentation using implemented MetFrag functionality matches theoretical fragment structures to measured MS/MS peaks and scores most likely structure.
D) Optional MS/MS Bucket matching enables to assign compounds with similar MS/MS spectra for identification of further possibly unknown but likely structurally similar compounds.
The identification of drug metabolites is not only of great interest to pharmaceutical research but has gained increasing interest in metabolomics, phenomics, exposomics and non-target screening workflows. Here, metabolites of drugs or other xenobiotics like pesticides, toxics or narcotics are expected to occur, which may belong to the family of unidentified, so-called dark metabolome compounds.
代谢®supports a localBioTransformer1-based metabolite prediction for assignment of these metabolism products both from liquid samples and directly from tissue using the SpatialOMx workflow. Additionally, changes in time of these metabolites can be tracked and semi-quantified by using integrated time series plots.

基于规则的注释例程®enable the identification of lipid species taking into consideration the Lipidomics Standards Initiative (LSI) guidelines. This Lipid Class (LC) annotation tool avoids this risk of over annotation and simplifies the automatic identification of lipid features.
代谢®can calculate and visualize Kendrick Mass Defects, turningcomplex mass spectral informationinto a组成图和优点的积分聚类based on lipid specific同源重复单元(例如CH2)。The customizable 4D Kendrick mass defect plot allows for intuitive lipid ID validation. Various characteristics of the extracted features can be plotted in 4 dimensions (x-axis, y-Axis, color scale, and bubble size), allowing versatile applications.
代谢组学和脂肪组学分析的主要要求是快速查明并确定因扰动或疾病而变化的化合物。匹配保留时间,前体质量,同位素模式和MS/MS光谱是获得复合注释置信度的常见标准。Pasef®关于timsTOF Proprovides hundreds of MS/MS events per second, resulting in a greater depth of fragment coverage in single analysis. Additionally, PASEF®spectra benefit from ion mobility separation, therefore cleaner MS/MS spectra are obtained using an on-the-fly mobility filter. Each MS value is complemented with a collisional cross section (CCS) value to give a measure of the shape of the analyte, providing further confidence to ID.
In conjunction withSCiLS™ Lab软件T-Rex²赋予了基于空间的非目标分析,用于处理和注释特征,包括药物代谢物,脂质和聚糖。MAP首次使用T-Rex³的独特组合在空间上进行了MAP分析,并将其与CCS感知的化合物注释相结合,以使使用MALDI成像在TimStof Flex系统上获得的化合物获得更高的置信度注释。
无色谱MRMS轴向工作流程provides higher sample throughput by omitting time-consuming chromatography in phenomics research. Compounds are accessible that are not readily detectable by LC-MS analysis, allowing targeted and non-targeted metabolomics approaches. The data extraction by T-ReX 2D in MetaboScape® provides confidence in automatic annotation of the FIA MRMS data. The novel scimaX MRMS system can show its extreme performance with mass resolutions of >1 million and mass accuracies of <0.2 ppm. The ultra-high resolving power enables you to utilze isotopic fine structure for the unambiguous determination of elemental composition. This adds another layer of confidence for compound ID in non-targeted metabolomics.
"The AQ concept has been recently complemented with collisional cross section values. This allows us to incorporate very reproducible CCS value measurements from the timsTOF Pro as additional and orthogonal parameters into our metabolite identification workflow."
"The performance of our new MRMS system has met and exceeded all our expectations across a variety of high end metabolic phenotyping challenges in molecular profiling, structure elucidation and imaging- and it is highly user friendly - every laboratory should have one!!"
