Procurement of 0863-254LNSY25001 Procurement project of single-cell tissue mass spectrometry imaging flow cytometry system(1)
| NO. | Product Name | Quantity | Main Technical Data | Remarks |
| Items 1 | Single cell mass spectrometry imaging flow system | 1 set | ★1. Purpose This technology is applied in various fields including cell biology, molecular biology, immunology, hematology, drug development, clinical diagnostics, cancer research, and pathogenic mechanisms through studies of suspended cells and tissue samples. It enables simultaneous detection of dozens of proteins at the single-cell level to generate detailed subpopulation profiles, playing a crucial role in advancing the discovery of biomarkers for scientific research and clinical applications, facilitating precise tissue structure analysis, and driving translational medicine studies. ★3.1.1 The number of channels is greater than or equal to 135. ★3.1.3 Instrument response in imaging mode: Lu175 signal ≥500 doul counts per shot. ★3.1.4 Number of antibody tags: provide at least 40 commercial tags (details provided). ★3.1.7 Simultaneous mass spectrometry flow suspension detection function, the system can switch between imaging mode and suspension detection mode. ★3.1.8 The sample is injected by positive pressure drive. ★ 3.1.21 The system automatically optimizes the detector voltage (Auto DV) to avoid excessive voltage changes caused by long-term acquisition, which will affect signal stability. ★3.2.3 Sample compatibility: Compatible with different forms of samples such as tissue section preparation method (FFPE) and frozen section; Slice thickness support: ≤7μm. ★3.2.4 The built-in optical microscope provides bright-field panoramic imaging to enhance workflow efficiency in selecting target areas. In imaging mode, the microscope field of view measures ≥200 μm × 250 μm ★3.2.5 Mass spectrometry imaging resolution: less than or equal to 1μm (supported by literature). ★ 3.2.6 Scanning speed: scan at 200Hz frequency, scanning area of more than 0.5mm2 per hour. ★ 3.2.7 Sample area: The sample area on the section with a searchable position should be at least 15mm × 45mm. ★ 3.2.8 Single cell mode imaging is available. ★3.2.10 Detection limit of the instrument in imaging mode is greater than or equal to 400 copies / μm2 |
