Collection: Protein Antigens

SEARCH TIP:

For more accurate results, include “Recombinant” in your search (e.g., “Recombinant IL-6 protein” or “Recombinant protein translocase subunit SecD”). You may also search by gene name (e.g., IL6, TNF, ACE2).

Protein antigens are proteins or protein-derived molecules recognized by the immune system and widely used in immunological research and assay development.

They are commonly used in:

• Vaccine and immunogenicity research
• Diagnostic assay development (ELISA, Western blot, etc.)
• Biomarker and pathogen detection
• Immunotherapy and antibody validation studies
