Stomach Matched Cancer and Normal Tissue MicroArray

Microarray Panel:
Primary cancer of FA
No. of samples: 30
No. of patients: 21
Core diameter: 2.0 mm
Format: Formalin Fixed
Section thickness: 4 micrometer
Please see manual for tissue information and location.

All tissues are fixed in 10% neutral buffered formalin for 12 to 24 hours, dehydrated with gradient ethanol, cleared with xylene, and embedded in paraffin. Then each slide is tested for immunohistochemistry on multiple antibodies including the p53 protein. Quality control is ensured as every tissue block is collected and arranged by certified pathologists, who used an identical process for their own research.

About 100,000 cells are included in each sample with 2 mm core diameter. Some slides may have less than 60 cores due to sample loss when obtaining multiple sections. Maximum number of missing cores in a slide is less than 10%.
