Beta-defensin 1 (BD-1) is a 36 amino acid peptide that has bactericidal activity in humans. It is encoded by the DEFB1 gene, and belongs to a family of microbicidal and cytotoxic peptides made by neutrophils. BD-1 is believed to function in the antimicrobial defense of the urogenital and respiratory tracts.

- Incubate 1.5 h at RT or O/N at 4°C.
- Add 100 µl standard or sample to each well.
- Incubate 2.5 h at RT.
- Add 100 µl prepared streptavidin solution.
- Incubate 45 min at RT.
- Add 100 µl TMB One-Step Substrate Reagent to each well.

Standard, biotinylated peptide, and positive control should be stored at -20°C after arrival. Avoid multiple freeze-thaws. The remaining kit components may be stored at 4°C. Opened microplate wells and antibody (Item N) may be stored for up to 1 month at 2° to 8°C. Return unused wells to the pouch containing desiccant pack and reseal along entire edge.
