IGSF8/CD316 in Neuro‑2A Mouse Cell Line. IGSF8/CD316 was detected in immersion fixed Neuro-2A mouse neuroblastoma cell line using Goat Anti-Mouse IGSF8/CD316 Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF3117) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Streptavidin (red; Catalog # NL999) and counterstained with DAPI (blue). Specific staining was localized to cell surfaces.

Background: IGSF8/CD316

IGSF8, also known as PGRL (PG regulatory-like protein), KASP (KAI/CD82 associated protein) and EWI-2 (Glu-Trp-Ile motif 2), is a widely expressed transmembrane adhesion protein. It interacts with beta 1 Integrins and various tetraspanins including CD9, CD81 and CD82. IGSF8 contains four extracellular Ig-like domains. IGSF8 overexpression in transformed cells inhibits cell migration and suppresses cancer metastatic potential. Mouse and human IGSF8 share 90% amino acid sequence identity.
