Principle of the Assay: This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for DEFA3 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any DEFA3 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for DEFA3 is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of DEFA3 bound in the initial step. The color development is stopped and the intensity of the color is measured.

NCBI Description

Defensins are a family of microbicidal and cytotoxic peptides thought to be involved in host defense. They are abundant in the granules of neutrophils and also found in the epithelia of mucosal surfaces such as those of the intestine, respiratory tract, urinary tract, and vagina. Members of the defensin family are highly similar in protein sequence and distinguished by a conserved cysteine motif. The protein encoded by this gene, defensin, alpha 3, is found in the microbicidal granules of neutrophils and likely plays a role in phagocyte-mediated host defense. Several alpha defensin genes are clustered on chromosome 8. This gene differs from defensin, alpha 1 by only one amino acid. This gene and the gene encoding defensin, alpha 1 are both subject to copy number variation. [provided by RefSeq, May 2010]

Uniprot Description

Function: Defensin 2 and defensin 3 have antibiotic, fungicide and antiviral activities. Has antimicrobial activity against Gram-negative and Gram-positive bacteria. Defensins are thought to kill microbes by permeabilizing their plasma membrane.4 PublicationsManual assertion based on experiment in:Ref.8

Product Notes

The Human DEFA3 defa3 (Catalog #AAA706289) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA706289 ELISA Kit recognizes Human DEFA3. It is sometimes possible for the material contained within the vial of "defensin, alpha 3, neutrophil-specific, ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
