Applications

Recommended Concentration

Sample

ELISA

This antibody functions as an ELISA capture antibody when paired with Sheep Anti-Human alpha ‑Defensin 1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8198).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human alpha-Defensin 1 DuoSet ELISA Kit (Catalog # DY8198-05) for convenient development of a sandwich ELISA.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Human alpha ‑Defensin 1 ELISA Standard Curve. Recombinant Human a-Defensin 1 protein was serially diluted 2-fold and captured by Mouse Anti-Human a-Defensin 1 Monoclonal Antibody (Catalog # MAB8198) coated on a Clear Polystyrene Microplate (Catalog # DY990). Sheep Anti-Human a-Defensin 1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8198) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Background: alpha-Defensin 1

Human Defensin alpha 1 (DEFA1) is 94 amino acids (aa) in length and is cleaved into the following chains: HP 1-56 (aa 39-94), Neutrophil defensin 1 (aa 65-94) and Neutrophil defensin 2 ( aa 66-94). Defensins are secreted peptides that kill microbes by permeabilizing their plasma membrane. DEFA1 has antimicrobial activity against Gram-negative and Gram-positive bacteria. ADP-ribosylation reduces cytotoxic and antibacterial activities, it is also known to enhance IL8 production. Phosphorylation at Tyr-85 is reported in several cancer cell lines and interferes with ADP-ribosylation of DEFA1.
