Specimen Procuring / Processing
Once tissue is procured from a surgical specimen, we will snap freeze the tissue in liquid nitrogen, fix the tissue in formalin, or freeze the tissue in OCT (frozen section media). Snap freezing tissue is our highest priority, followed by formalin fixation and OCT embedding. Frozen tissue is stored inside cassettes in our -80° upright freezers. The formalin fixed tissue is sent to the Core Lab to be processed, embedded, cut and stained. We obtain a formalin fixed paraffin embedded block and an H&E stained slide for each tissue sample we fix in formalin and store these in our facilities.
