Human Gelsolin ELISA Kit

Human Gelsolin ELISA Kit (ab270215) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Gelsolin protein in edta plasma, serum, cit plasma, and hep plasma. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human Gelsolin with 145.98 pg/ml sensitivity.

SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:

- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips

A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

Gelsolin (GSN) is an 82-kD protein with six homologous subdomains, referred to as S1-S6. Each subdomain is composed of a five-stranded β-sheet, flanked by two α-helices, one positioned perpendicular with respect to the strands and one positioned parallel. The β-sheets of the three N-terminal subdomains (S1-S3) join to form an extended β-sheet, as do the β-sheets of the C-terminal subdomains (S4-S6). It is regulated by calcium and modulates actin by binding to the plus (or barbed) ends of actin filaments, preventing monomer exchange (end-blocking or capping). It can promote the assembly of monomers into filaments (nucleation) as well as sever filaments already formed. Gelsolin plays a role in ciliogenesis. Human Gelsolin shares 99%, 93%, 93%, and 96% sequence homology with monkey, mouse, rat, and bovine, respectively.
