Detects mouse IGSF8/CD316 in direct ELISAs. Detects human and mouse IGSF8/CD316 in Western blots. In direct ELISAs, approximately 15% cross-reactivity with recombinant human IGSF8 is observed and less than 1% cross-reactivity with recombinant mouse IGSF4 is observed.
Detection of Human and Mouse IGSF8/CD316 by Western Blot.
Western blot shows lysates of SH‑SY5Y human neuroblastoma cell line, DU145 human prostate carcinoma cell line, and bEnd.3 mouse endothelioma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Mouse IGSF8/CD316 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3117) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). Specific bands were detected for IGSF8/CD316 at approximately 70-80 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of IGSF8/CD316 in Neuro‑2A Mouse Cell Line by Flow Cytometry.
Neuro‑2A mouse neuroblastoma cell line was stained with Goat Anti-Mouse IGSF8/CD316 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3117, filled histogram) or isotype control antibody (Catalog # AB-108-C, open histogram), followed by Phycoerythrin-conjugated Anti-Goat IgG Secondary Antibody (Catalog # F0107).
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 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3117) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cell surfaces. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

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.
