Tissue H&E Staining Image
Flowchart of LCM for The Product Preparation
- FFPE samples are cut at 6 microns and mounted onto pen membrane glass slides and let the slides dry for 2 hours at room temperature.
- After deparaffinization and rehydration, quick H&E staining is performed.
- Arcturus XT Laser Microdissection System is used for LCM. Microdissection is performed using IR and UV laser and CapSure Macro LCM Cap.
- The total dissected cells may be varied between 10,000 to 50,000 cells which depend on tissue type.
- Protein is extracted from LCM Caps by following the protocol from Methods; 2016, 104: 154-162
- The tissue H&E staining slides are examined by certified pathologists. Pathological re-confirmation report is generated and digital image captured.
- LCM is supervised by our certified pathologist.
- Three example LCM images including Before, After LCM, and LCM cap images from LCM tissue slides are taken to demonstrate the dissected cells.
Extraction Protocol for Protein from LCM Caps
For protein extraction, you can follow the protocol from Longuespée R, et al. A laser microdissection-based workflow for FFPE tissue microproteomics: Important considerations for small sample processing, Methods;2016, 104: 154-162
Product Format and Size:
Protein in 50 μl of lysis buffer from 2 LCM caps.
The protein lysate can be used for proteomics.
Store at -80ºC
