Polyclonal Antibodies

Assaypro’s polyclonal antibodies are expertly produced to deliver high-affinity binding and broad epitope recognition across a variety of research and diagnostic applications. Generated from the serum of immunized animals, our polyclonal antibodies detect multiple epitopes on the same antigen—providing increased signal strength and sensitivity, especially in low-abundance targets or denatured proteins.

Whether you’re conducting ELISA, Western blot, immunohistochemistry (IHC), or immunoprecipitation (IP), Assaypro polyclonal antibodies offer dependable performance, even in complex or variable sample conditions. Each antibody is thoroughly characterized and quality-controlled to ensure specificity, minimal cross-reactivity, and lot-to-lot consistency.

Features & Benefits

• Broad Epitope Recognition – Targets multiple regions of the antigen for stronger and more reliable signal detection.
• Optimized for Versatility – Validated for use in ELISA, Western blot, IHC, IP, and more.
• High Sensitivity – Ideal for detecting low-expression proteins or partially denatured targets.
• Rigorous Quality Control – Every lot is tested for performance, purity, and specificity to ensure research-grade quality.

Applications

• ELISA – Sensitive detection in quantitative assays
• Western Blot – Strong signal across a range of protein sizes
• Immunohistochemistry (IHC) – Tissue localization with robust staining
• Immunoprecipitation (IP) – Effective target capture for downstream analysis
