Product Description
Human Defensin, alpha 1 (DEFA1) ELISA Kit | KTE62559 | Abbkine
Application: This Human Defensin, alpha 1 (DEFA1) ELISA Kit employs a two-site sandwich ELISA to quantitate DEFA1 in samples. An antibody specific for DEFA1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyDEFA1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for DEFA1 is added to the wells. After washing, Streptavidin 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 DEFA1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Detection Method: Colorimetric
Conjugate: N/A
Sample Type: Cell culture supernatants#Serum#Plasma#Other biological fluids
Assay Type: Multiple steps standard sandwich ELISA assay with a working time of 3-5 hours. It depends on the experience of the operation person.

Usage Note: • Do not mix components from different kit lots or use reagents beyond the kit expiration date.
• Allow all reagents to warm to room temperature for at least 30 minutes before opening.
• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.
• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.
• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.
• It is recommended that all samples and standards be assayed in duplicate or triplicate.
Storage Instruction: The unopened kit should be stored at 2 - 8°C. After opening, please store refer to protocols.
Shipping: Gel pack with blue ice.

Background: Defensins are cytotoxic peptides and have a well-defined role in host defense. 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. Several alpha defensin genes appear to be clustered on chromosome 8.The defensin, alpha 1 protein, is found in the microbicidal granules of neutrophils and likely plays a role in phagocyte-mediated host defense. It differs from defensin, alpha 3 by only one amino acid.
