Human Keratin 7 (KRT7) ELISA Kit

Quantitative analysis of cytokeratin 7 (KRT7) in human research specimens is supported by an enzyme-linked immunosorbent assay from Assay Genie. Cytokeratin 7 is a type II intermediate filament protein selectively expressed in simple and glandular epithelia, where its restricted distribution makes it a useful marker for identifying tissue of origin in metastatic adenocarcinomas involving the lung, breast, endometrium, cervix, and biliary tree.

Researchers investigating cholangiocarcinoma, breast carcinoma biomarkers, and epithelial-mesenchymal transition pathways rely on this Assay Genie kit to complement western blot and immunohistochemistry data. Configured for 96 assays per kit, the assay is processed on a standard microplate and read on a conventional microplate reader for absorbance-based quantitation. Each shipment includes a pre-coated microplate, assay buffers, detection reagents, calibration standards, and a printed protocol sufficient to complete the full run.

Specimens should be aliquoted and stored frozen at -20 °C or lower, and repeated freeze-thaw cycles should be avoided to preserve analyte integrity. The kit is labeled for research use only and is not intended for clinical diagnostic applications. Assay Genie supports the product with technical documentation for standard curve generation, sample preparation guidance, and troubleshooting.
