Anti-bacterial primary antibodies enable specific detection, identification, and characterization of bacterial pathogens in clinical, food safety, and research applications through targeted binding to bacterial surface antigens, lipopolysaccharides, and virulence factors.
These reagents support immunohistochemistry, flow cytometry, ELISA, and Western blotting with high sensitivity and minimal cross-reactivity.
Types and Production Methods
Polyclonal Antibodies
- Generated by immunizing animals (goats, rabbits) with heat-inactivated whole bacterial cells or purified antigens.
- Affinity-purified against native surface epitopes using proprietary protocols.
- Broad epitope coverage provides high avidity and robustness against strain variations.
- Lot-to-lot consistency achieved through standardized bleed selection and cross-reactivity testing.
Monoclonal Antibodies
- Derived from hybridoma technology or recombinant display libraries (phage, yeast).
- Single epitope specificity enables precise serotyping and antigen quantification.
- Humanized formats reduce immunogenicity for therapeutic applications.
- Recent advances include transgenic mice immunized with outer membrane vesicles to generate monoclonal antibodies against multidrug-resistant Acinetobacter baumannii.
