FGFR2b Antibody: A New Hope for Targeted Therapy in Gastric Cancer

1. Literature Information

This review highlights FGFR2b as a pivotal therapeutic target in gastric cancer and demonstrates the critical role of FGFR2b companion diagnostic antibodies in patient screening and precision therapy.

2. Research Background

FGFR2b is an epithelialspecific splicing isoform of FGFR2. Its overexpression and activation drive proliferation, invasion, and therapy resistance in gastric cancer. Effective companion diagnostics are essential to identify eligible patients for antiFGFR2b therapies.

3. Research Approach

FGFR2b antibodies enable IHCbased detection of membrane expression in FFPE tissues. Pathological evaluation assesses staining intensity and positive cell percentage to guide treatment decisions.

4. Research Outcomes

· FGFR2b activates MAPK, PI3K/AKT, and JAK/STAT pathways to promote tumor progression.

· Approximately 5–10% of gastric cancers show FGFR2b overexpression.

· FGFR2b IHC predicts response to monoclonal antibodies and ADCs.

· Standardized scoring ensures reliable patient stratification.

5. Product Empowerment

ANT BIO PTE. LTD. provides FGFR2b Recombinant Rabbit mAb (S0B2232).

· High specificity without crossreactivity to FGFR2c or other FGFRs.
