BioRam 活体单细胞显微激光拉曼光谱仪 基于拉曼显微光谱技术的单细胞分选方法无需外加标记,可无损获得整个单细胞的化学物质指纹图谱,从而迅速识别活体单细胞的种系发生、生理特性和代谢产物变化等,因此对于难培养微生物的功能鉴定和资源开发具有重要意义。
系统亮点概述 相比于利用FACS或MACS原理来进行细胞识别的仪器,BioRam拉曼光谱仪无需使用磁珠,生化标记物或荧光标记物,可在整个过程中保持细胞的活性。 测试后的细胞可以传代培养以用于进一步的实验。在这种过程中,由于细胞的活性保持不变,所以可以对癌细胞的特征进行分析,并可以对它们与各种活性物质相互作用的效果进行分析。BioRam的应用范围涵盖从生物研究到临床实践,可对病人的具体治疗决策进行支持。 图2 对细胞表面氨基酸的拉曼指纹图谱分析 (2)即使在液体环境中,也可对细胞进行精确分析 图3 对于不同血液细胞的拉曼光谱分析 (3)测量技术简单易行 (4)允许培养组织进行非侵入性分析 3、适用范围

CellTool develops various analytical platforms tailored to different applications in biomedical research and clinical diagnostics. All of them comprise as basic components a high-end microscope, a Raman laser, elements for laser-beam guidance, a spectrograph for signal detection and a PC or Mac for automated system control. The platforms differ in terms of add-on modules, sample mount and software, which are adapted to the respective application.
For each system, CellTool also supplies the required consumables, e.g. tailored microfluidic slides, Raman-compatible petri dishes or sample preparation kits for certain probes.
BioRam, CellTool’s most advanced analytical platform, is available for customers.
Adapted to living samples – BioRam comprises all the basic components (see overview), together with a temperature-controlled and contamination-proof chamber for living biological samples and specific software for system control and data analysis. The basic version can be upgraded with microfluidics for increased throughput and contact-free sorting of cells. BioRam allows verification of spectroscopic results comparing them with conventional fluorescence measurements.
Samples can be used without special preparation: as living tissue, in aqueous solution on Raman-compatible slides or directly in culture medium in Raman-compatible petri dishes or fluidic chips. With a 3D-mouse, you can home in on the cells to be analysed and start the automatic generation of Raman spectra with a mouse click. Cells are then automatically identified according to their spectra by database comparison. Measurement coordinates, live images, raw data and all the relevant parameters are saved as well, enabling further analysis or the application of alternative algorithms at any time.
