产品详情

Human Cytokeratin 19 ELISA Kit (ab252367) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Cytokeratin 19 protein in cell culture extracts. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human Cytokeratin 19 with 375 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.

Cytokeratin 19, also known as KRT19, is an intermediate filament protein that gives structure to epithelial cells. Beyond its role as a structural protein, KRT19 is involved in cell signaling pathways including Wnt/Notch and EGR1/PTEN/AKT, although the response to altered expression is highly cell-type dependent. Expression levels of this protein are altered in many types of cancers, and it is currently used as a biomarker for breast cancer.The standard is affinity purified.
