Caratteristiche

Unbiased, deep HTS by label-free mass spectrometry

MPP代表Bruker Pharmapulse的旗舰成员®生产线。它具有Maldi的极端速度和稳健性,并且在HTS中首次利用了Bruker的创新捕获的离子移动光谱法(TIMS)技术。TIMS通过利用分子碰撞横截面来实现异橡胶甚至异构体的快速气相分离。这与常规的50,000质量分辨率结合在QTOF-MS检测中,使得在HTS速度下具有革命性的测定特异性水平。
TimstofMPP uses a dual MALDI / ESI ion source with industry-leading 10 kHz smartbeam™ 3D laser to enable uHTS compatible speed and throughput, and is available with the unique MALDI-2 option for an expanded chemical space.

As part of the solution, the new MALDI PharmaPulse®2023年软件支持广泛的HTS应用程序用于药物发现。它的自动化接口允许在高通量环境中集成MPP,并与来自各种供应商的调度软件协同合作。此外,MPP 2023可以将数据和结果无缝传输到下游分析软件,例如GenEdata筛选器®.

Benefici

Exceptional data quality delivered at uncompromised HTS speed

TimstofMPP delivers high-resolution accurate-mass QTOF-MS data at high analysis speed throughout large acquisition campaigns – a key requirement for success in uHTS. Readout of a 1536 formatted sample plate in high-resolution MS or MS/MS mode takes less than 10 minutes, typically (reading rates up to 3 wells / sec). Outstanding data quality is maintained throughout large scale measurements ensuring precise quantitative feature extraction for a broad variety of target molecules ranging from small drug-like compounds up to large sized peptides translating into minimized false discovery rates (FDR).

Mass accuracy monitored for two peptide ions over a time window of more than 5 hours:

The TIMS benefit: Fast separation of isobars and isomers

TIMS能够在时间尺度上分离异构体甚至异构体比SPE的速度明显快(通常为每个分离周期≤1秒),从而可以单独通过质谱法无法区分目标化合物的无干扰定量。

Example:Quantitative MALDI-TIMS-MS analysis of glucose (C6H12O6) in presence of isomeric fructose (C6H12O6)

Advanced timsTOF operation modes for enhanced quantitation results

在HTS中,靶化合物的定量可能会受到生化或细胞测定中通常存在的复杂样品矩阵的影响。TimStof MPP提供了克服这种背景干扰的独特可能性:引人入胜的离子迁移率光谱法(TIMS)在气相中进行快速分离,并利用高分辨率MS和MS/MS提供的提高特异性,高级MPP操作模式可有效地最小化背景干扰水平导致HTS速度下的定量增强。

Example:Quantitative analysis of a drug-like molecule (MW 543 Da)
Quantitation in MALDI-MS mode is disrupted due to spectral overlap with assay background. Performing the same analysis in MALDI-TIMS-MS/MS mode enables interference-free quantitation of the target molecule.

Applicazioni

酶活性筛选在最短的时间启用

在Maldi Pharmapulse上进行无标签的酶活性监测®以HTS速度和最高水平的性能。

In a proof-of-concept study, differently bioengineered enzyme variants were assayed for their activity by quantifying glucose as a final product of enzymatic conversion using13C6glucose as an internal standard. High-resolution accurate-mass data delivered by timsTOF MPP allowed for robust and reliable target feature extraction resulting in outstanding RSD values between 0.1 and 3.7 %.

在接近实时支持HTE化学中,启用CCS的合成筛选

为了寻找新药分子,高通量实验(HTE)通过多变量的高通量化学创建了新设计的化合物的广泛库。在此过程中,关键的瓶颈是化学反应产物的快速分析和确认。

TimstofMPP is capable of keeping the pace with HTE chemistry and enables near real-time verification of synthesis products at a high convidence level by measuring multiple physical properties, i.e. accurate molecular mass, isotopic pattern, collisional cross-section (CCS) and, on-demand, CID-MS/MS fragmentation data, reducing HTE feedback time and chemical costs.
