Product Images

HEK293T cells were transfected with the pCMV6-ENTRY control (Left lane) or pCMV6-ENTRY KRT19 (RC209707, Right lane) cDNA for 48 hrs and lysed. Equivalent amounts of cell lysates (5 ug per lane) were separated by SDS-PAGE and immunoblotted with anti-KRT19. Positive lysates LY419428 (100ug) and LC419428 (20ug) can be purchased separately from OriGene.

• 

  Western blot analysis of extracts (35ug) from 9 different cell lines by using anti-KRT19 monoclonal antibody.

• 

  Immunohistochemical staining of paraffin-embedded Human bladder tissue within the normal limits using anti-KRT19 mouse monoclonal antibody. (Heat-induced epitope retrieval by 10mM citric buffer, pH6.0, 100°C for 10min, TA500019)

• Background: Keratin 19 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.
• Synonyms: CK19; K1CS; K19
