Mucin 2, Immunostain, Technical Component Only
Use
Mucin 2 (MUC2) is a 520 kDa glycoprotein belonging to the family of secretory mucins. MUC2 is expressed in the cytoplasm of goblet cells. An immunopanel consisting of MUC1, MUC2, MUC5AC, and MUC6 is useful in subtyping intraductal papillary mucinous neoplasms. This test aids in subtyping intraductal papillary mucinous neoplasms, providing valuable insight into their classification.

Limitations
Age of a cut paraffin section can affect immunoreactivity. Stability thresholds vary widely among published literature and are antigen dependent. Best practice is for paraffin sections to be cut within 6 weeks. The charge of glass slides can be affected by environmental factors and subsequently may alter slide staining. Sending unsuitable glass slides can result in inconsistent staining due to poor slide surface chemistry.

Collection Instructions
Attach the green 'Attention Pathology' address label (T498) and the pink Immunostain Technical Only label included in the kit to the outside of the transport container. Preferred specimen is Formalin-fixed, paraffin-embedded tissue block or 2 Unstained, positively charged glass slides (25- x 75- x 1-mm) per test ordered.
Storage Instructions
Best practices for storage of positively charged slides: Minimize time slides are stored after being unpackaged, limit exposure to high humidity and heat, minimize exposure to plastics.
