Biotinylated anti-guinea pig primary antibodies are highly specific immunoreagents used to detect guinea pig-derived antigens or immunoglobulins in diverse immunoassays. Biotin is covalently attached to antibody lysine residues while preserving antigen-binding activity, enabling sensitive and flexible detection through avidin- or streptavidin-based systems.

Biotin-Avidin Detection System

These antibodies exploit the exceptionally high-affinity interaction between biotin and avidin or streptavidin, providing efficient signal amplification. Carefully optimized biotin labeling preserves antibody stability and specificity while maximizing detection sensitivity.

Applications and Advantages

• Broad Compatibility: Suitable for immunohistochemistry (IHC), Western blotting, ELISA, immunocytochemistry, and ELISpot assays.
• High Sensitivity: Multiple biotin molecules enable amplified detection using enzyme- or fluorophore-conjugated avidin/streptavidin complexes.
• Important Considerations: Blocking endogenous biotin and avoiding excessive biotinylation help minimize background staining while maintaining antibody solubility, stability, and optimal analytical performance.
