Product details:
Human Elafin ELISA Kit (Skalp) ab100658 is a sandwich ELISA to measure Human Elafin (Skalp) in serum, plasma, cell culture supernatant with a sensitivity of 5 pg/ml.
How the assay works
This assay employs an antibody specific for Human Elafin coated on a 96-well plate. Standards and samples are pipetted into the wells and Elafin present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human Elafin antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Elafin bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
Assay Specificity
Our ELISA kits are rigorously validated to ensure the highest level of consistency and reproducibility. Please check the protocol booklet for more details

Elafin also known as ESI or ESI protein is a small serine protease inhibitor with a molecular mass of around 6 kDa. This protein produced by epithelial cells resides predominantly in the skin lungs and other mucosal surfaces. The Elafin protein plays an important mechanical role in inhibiting neutrophil elastase and proteinase 3. It contributes to the regulation of protease activity within tissues controlling inflammation and repair processes.
Biological function summary
Elafin interacts intimately with protease inhibitors to guard tissues against excessive proteolytic damage. It does not typically form large complexes but functions as part of the innate immune defense. This protein helps to neutralize the action of neutrophil elastase which can help maintain the integrity of connective tissue extracellular matrix. Despite its standalone function Elafin's activity serves in tandem with other inhibitors in the protease-antiprotease balance.
Pathways
Elafin integrates prominently into the proteolytic and inflammatory pathways. It functions particularly in the inflammation and immune response pathways coordinating with proteins like secretory leukocyte protease inhibitor (SLPI) and alpha-1 antitrypsin. Elafin inhibits enzymes that degrade connective tissue components. Therefore it plays an important role in modulating inflammatory responses and tissue remodeling post-injury.
Connections between Elafin and conditions such as chronic obstructive pulmonary disease (COPD) and psoriasis appear significant. These diseases relate to abnormal protease activity and chronic inflammation where Elafin's inhibitory function can be affected or diminished. Studies have shown that altered Elafin levels link with these diseases alongside proteins like neutrophil elastase and matrix metalloproteinases which contribute to tissue damage. Researchers continue to explore Elafin's therapeutic potential in managing such inflammatory conditions.
