I CD155
Use
CD155 is a cell surface protein involved in cell adhesion and immune modulation, particularly through interactions with immune checkpoint receptors. In pathology, CD155 serves as an important marker for assessing tumor progression, particularly in malignancies like head and neck squamous cell carcinoma and melanoma, where its expression correlates with increased tumor invasiveness and poor prognosis.

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). Samples may be fixed in formalin for 24-72 hours by collection sites, then transferred to 70% ethanol and stored at 2-8°C for longer-term storage if needed. Samples must be tested 3 months after placing in ethanol.
Storage Instructions
15°C to 25°C
Causes for Rejection
Specimens must be fixed in 10% NBF or B plus. All other fixatives will be rejected.
