Reticulum Stain, technical only
Use
Reticulum special stain is used to highlight reticular fibers, which are composed of type III collagen typically found in lymphoid tissues, the liver, and bone marrow. This stain is particularly useful in diagnosing disorders such as hematologic malignancies, cirrhosis, and conditions involving fibrosis.
Special Instructions
Technical component only. Pathologist read not included. Fresh Tissue: Specimens may be fixed in formalin for 6-72 hours by collection sites, then transferred to 70% ethanol and stored at 2-8°C for longer term storage if needed. This is NOT preferred. Samples should be tested 3 months after placing in ethanol. Unstained slides: Positively charged glass slides required to prevent background staining and prevent tissue loss. Slides should be left unbaked.
Limitations
Stated turn-around-times (TATs) are for clinical use only and subject to change based on biopharma protocol requirements. Final TATs will be specified in the biopharma study contract. Specimens must be fixed in 10% NBF or B plus. All other fixatives will be rejected.
