Fresh Frozen Tissue Collection
All fresh frozen tissue samples are collected under IRB approval by certified medical pathologists. Tissues are snap-frozen in liquid nitrogen within 30 to 60 minutes of surgery excision. Standard sample weight is 0.5 – 1.0 gram. Samples can be collected/embedded in Optimal Cutting Temperature (OCT) media upon request. Tissues are stored in vapor-phase liquid nitrogen (-190°C). Frozen tissues are never allowed to thaw after initial freezing. Fresh frozen tissue specimens are collected under a strict Standard Operating Procedure (SOP). Quality Control (H&E staining and RNA analysis) is performed on 100% of collected tissue samples. Custom collections for fresh frozen tissues are available.
From excision to storage to shipment, each specimen is handled with care and precision to ensure that the highest quality specimens are delivered to our customers.
