About Cytokeratin 19
The protein encoded by this gene is a member of the keratin family. The keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into cytokeratins and hair keratins. The type I cytokeratins consist of acidic proteins which are arranged in pairs of heterotypic keratin chains. Unlike its related family members, this smallest known acidic cytokeratin is not paired with a basic cytokeratin in epithelial cells. It is specifically expressed in the periderm, the transiently superficial layer that envelopes the developing epidermis. The type I cytokeratins are clustered in a region of chromosome 17q12-q21.

About CF594
CF®594 from Biotium is a fluorophore with an excitation peak at 593 nm and an emission peak at 614 nm. It can be useful in both fluorescence microscopy and flow cytometry. It is spectrally similar to Alexa Fluor™ 594, DyLight™ 594 and Texas Red. However, in flow cytometry, PE-CF®594 and PE-Dazzle 594 are superior alternatives. In microscopy, CF®594 has been validated in STED and 2-Photon microscopy.
