Tissue H&E Staining and IHC images
Ki 67 IHC
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. The DNA is extracted from Caps by using Arcturus® PicoPure® DNA Extraction Kit (Thermo Fisher, KIT0103).
- Extracted DNA is quantized by UV adsorption in a NanoDrop.
- The tissue H&E staining slides are examined by certified pathologists. Pathological reconfirmation 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.
- Quality scoring of FFPE genomic DNA and degraded genomic DNA is not tested, requiring researchers to evaluate.
