Mucicarmine Stain, technical only
Use
Mucicarmine special stain is used to detect epithelial mucins in tissue sections. Mucicarmine stain aids in the identification of mucin-producing tumors, such as adenocarcinomas, and distinguishing them from non-mucin-producing tumors. Additionally, mucicarmine staining is valuable in diagnosing fungal infections caused by encapsulated organisms, as it highlights the presence of the fungal capsule. Technical component only. Pathologist read not included.
Special Instructions
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.

Collection Instructions
Fixative should be at a 20:1 fixative to tissue ratio, 10% neutral buffered formalin (NBF) for 6-72 hours (48-72 hours PREFERRED). Specimens may be transferred to 70% alcohol for transportation purposes after fixation.
Storage Instructions
Stored at 15°C to 25°C. Use a refrigerated (NOT FROZEN) gel pack in the shipment to protect from extreme temperatures.
Causes for Rejection
Specimens must be fixed in 10% NBF or B plus. All other fixatives will be rejected.
