FFPE Blocks and Sections

Formalin-Fixed Paraffin-Embedded (FFPE) samples are ideal for rapidly identifying the cellular localization of DNA, RNA and protein. To make paraffin tissue blocks and sections, tissues are excised, immediately fixed by formalin, processed, embedded, sectioned, stained and then pathologically identified. The paraffin-embedded tissue section with 4-10 µm thickness is mounted on a positively charged glass slide.

VitroVivo Biotech provides high quality human and mouse FFPE blocks and section tissue slides which can be used for routine H&E stain or other special staining, IHC, IF, FISH and ISH. We also provide positive control slides for your histopathology positive experiment control.
