特征

Rapiflex®MALDI PHARMAPULSE®

The all new rapifleX® MALDI Time-of-Flight mass spectrometer is the heart of the MALDI PharmaPulse®, it incorporates Brukers latest 10 kHz scanning laser technology and can read multiple samples per second. All components of the system work in concert for fully automatic HTS operation. The newly designed screening software suite supports HTS workflows and works in combination with a proprietary assay development module which empowers assay developer to accelerate label-free assay development for MALDI mass spectrometry. The latest ‚Synthesis Screening‘ software module of the rapifleX® MPP opens a new application space for e.g. monitoring of chemical reactions at high pace or analysis of binding assays at incomparable high throughput and specificity.

Rapiflex®MALDI PHARMAPULSE®(MPP) combs through large compound libraries of millions of substances

The use of mass spectrometry allows the measurement of unmodified substrates in primary screens to avoid false positives or false negatives, making confirmation screens redundant. The system is designed for fully automatic handling of 384 and 1536 sample plates to screen more than a million compounds in a week in support of drug discovery.

超高通量筛查标签的“命中”标识的新标准

通过将Bruker专利的SmartBeam 3D激光技术的速度与质谱的直接检测能力相结合,Rapiflex®MPP delivers unprecedented screening capability for ultra high-throughput screening of biochemical and cellular assays. It allows you to screen through large and diverse compound libraries at a pace of over a million compounds a week, epitomizing the perfect balance of automation and miniaturization.

Benefits

Rapiflex Maldi Pharmapulse

The rapifleX®MPP assists assay development, accelerates HTS and uHTS hit finding, and supports hit confirmation and lead optimization

MPP系统允许在原发性生化筛选中测量未修饰的底物,并提供多个优点:

  • 它有效地消除了通常需要基于传统荧光的筛选技术所需的验证性测定
  • Saves costs for developing specific fluorescence probes or antibodies
  • 不需要昂贵的溶剂或消耗品即可连续操作
  • Allows sample volume down to 25 nL

Pharmapulse溶液

Pharmapulse解决方案基于Bruker的高级MALDI-TOF技术和专用软件包。在开发过程中,易于使用和时间是关键驱动因素,从而产生了直观但功能强大的软件解决方案,以测量和分析数百万个完全自动化的样本。两个工作流程指导用户从对MALDI质谱进行调整,以便在LIMS系统中进一步分析结果。

新软件模块支持合成筛选和绑定测定

在生化筛选实验中,Rapiflex®MPP确定在存在潜在抑制剂的情况下进行生化测定时的转化率。在这样的屏幕中,比较产物和底物强度的明显MS峰值比在大量样品斑中进行监测,其中每个斑点代表相同的生化转化反应,但测量了不同抑制剂分子的有效性。

除了此筛选功能外,新的MPP软件模块还支持“综合筛选”,该方法学需要更高的灵活性,以实现MALDI-TOF MS的目标。在这里,感兴趣的M/Z值可能因点而异,因为每个样品可能代表不同的化学反应。因此,新的MPP“合成筛选”软件模块允许科学家筛选每个样品点的大量化合物。因此,这项新的基于MALDI-TOF的高通量分析工作流可以使高度及时的化学反应性景观的测量深度在以前看不见的映射深度上进行测量。
