Head and Neck Squamous Cell Carcinoma Reagents

Home > Featured Products > Oncology Research > Head and Neck Squamous Cell Carcinoma

HNSCC is strongly associated with HPV infection (oropharyngeal) and tobacco/alcohol exposure (non-HPV). EGFR remains the only approved targeted therapy, while PD-1 checkpoint blockade has become first-line for recurrent/metastatic disease. abinScience provides reagents for EGFR, PD-L1, HPV/p16, TROP2, Nectin-4, and B7-H3.

Common Research Applications

HPV-positive vs. HPV-negative stratification: Apply p16/CDKN2A IHC antibodies as a surrogate for HPV status in oropharyngeal cancer, complemented by HPV E6/E7 antibodies for confirmatory testing.
PD-L1 CPS scoring: Use anti-PD-L1 antibodies for research-use IHC to assess Combined Positive Score (CPS) for immunotherapy eligibility studies in HNSCC cohorts.
EGFR-targeted therapy development: Recombinant EGFR-ECD proteins and biosimilar cetuximab for binding kinetics, epitope mapping, and cell-based ADCC assays in HNSCC cell lines.
Squamous differentiation panel: p63, CK5/6, and CK14 antibodies available for squamous differentiation research. See product pages for validated applications.

FAQs

Which p16 antibodies work for HPV status IHC?

Anti-p16/CDKN2A antibodies available. See product pages for validated applications. Research use only.

Do you carry EGFR biosimilar reference proteins?

Yes. Research-grade cetuximab and panitumumab biosimilar proteins with ELISA, FACS, and Functional assay validation.

What B7-H3 reagents are available?

Anti-B7-H3/CD276 antibodies and research-grade biosimilar proteins available. See product pages for validated applications.

Do you offer multiplex IHC panels for HNSCC?

We provide individual validated antibodies for PD-L1, CD8, CD68, p16, and EGFR that can be combined in sequential or multiplex IHC workflows. Contact us for panel design guidance.

Can I get custom antibodies for novel targets?

Yes — our parent company AtaGenix provides full custom antibody development from immunogen design through hybridoma production and characterization, including targets not yet in our catalog.
