Cytokeratin 19, also known as keratin 19, is a type I intermediate filament protein with a molecular weight of approximately 40-44 kD. Cytokeratin 19 is a heterotetramer composed of two type I and two type II keratin subunits. Unlike other cytokeratins, cytokeratin 19 lacks a C-terminal non-helical extension. This cytokeratin is widely expressed in the periderm (transient superficial layer enveloping developing epidermis), muscle, intestine, bile duct, esophagus, stomach, and thymus. Cytokeratin 19 can be upregulated by vitamin A and is thought to play a critical role in embryogenesis. Cytokeratin 19 intereacts with the pinin protein and has been shown to be modified by phosphorylation (Ser10, Ser35).Product Details
- Antibody Type
- Host Species
- Human mammary carcinoma cell line MCF-7
- This antibody is provided in 50% glycerol in aqueous buffered solutions with preservatives.
- The antibody was purified by affinity chromatography and conjugated with HRP under optimal conditions.
- Lot-specific (please contact technical support for concentration and total µg amount, or use our Lookup tool if you have a lot number.)
- Storage & Handling
- Upon receipt, the antibody solution should be stored undiluted at -20°C, and protected from prolonged exposure to light.
WB - Quality tested
- Recommended Usage
Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 0.1-0.5 µg per ml (1:1000-1:5000 dilution). It is recommended that the reagent be titrated for optimal performance for each application.
25 µl and 100 µl of Direct-Blot™ HRP antibody can be used for approximately 5 and 20 Western blots, respectively, at the recommended concentration/dilution.
- Application Notes
Additional reported applications (for the relevant formats) include: immunoprecipitation, immunohistochemistry of paraffin-embedded sections, immunocytochemistry, and ELISA.
