Human Keratin, type I cytoskeletal 9 (KRT9) ELISA Kit

Designed for research use, this Sandwich ELISA from Assay Genie enables the quantification of human Keratin, type I cytoskeletal 9 (KRT9), a type I cytoskeletal keratin that contributes to the structural integrity of epithelial cells. The assay is reactive with human samples, and the manufacturer indicates specificity toward natural and recombinant human Keratin, type I cytoskeletal 9.

According to the source, KRT9 may serve an important special function in mature palmar and plantar skin tissue or in the morphogenetic program of formation of these tissues, and plays a role in keratin filament assembly. The protein is reported to form a heterotetramer of two type I and two type II keratins, and dysregulation of its expression has been implicated in various dermatological conditions, making it a biomarker of interest for related research.

The kit uses a colorimetric detection method and is intended for use with serum, plasma, tissue homogenates, cell culture supernates and other biological fluids. The reported detection range is 0.156-10ng/mL with a sensitivity of 0.084ng/mL. Synonyms listed for the target include Cytokeratin-9, Keratin-9, CK-9 and K9; the associated UniProt entry is P35527.
