Western blot analysis of extracts from A549(lane 2(20ug) , MCF-7(lane 3(20ug) and HepG2(lane 4(20ug),K562(lane 5(20ug) using Cytokeratin 19 Antibody (HY-P81183) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P83730, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.

Flow Cytometry analysis of MCF-7 cells labelling Cytokeratin 19(red) with Cytokeratin 19 Antibody (anti-Cytokeratin 19) (HY-P81183). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Then cells were stained with the primary antibody at 1/200 dilution for an hour at 4℃. Goat Anti-Rabbit IgG H&L (AF488) (HY-P8002) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Rabbit IgG Isotype Control(HY-P80879, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).

Cells were fixed in 4% paraformaldehyde for 20 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 5 minutes at room temperature, then blocked with 1% BSA/10% normal goat serum for 1 hour at room temperature. Cells were then incubated with Cytokeratin 19 (HY-P81183) at 1/100 dilution in 1% BSA in PBST overnight at 4 ℃. Alexa Fluor® 647-conjugated AffiniPure Goat Anti-Rabbit IgG H&L (HY-P80952) was used as the secondary antibody at 1/1,000 dilution. Nuclear DNA was labelled in blue with DAPI. -

Background
-
Function
Cytokeratin 19 is involved in the organization of myofibers. Together with KRT8, helps to link the contractile apparatus to dystrophin at the costameres of striated muscle
-
Expression
Tissue_specificity:It is expressed in specific basal keratinocyte regions of the deep outer root sheath of hair follicles. It is also found in sweat glands and mammary ducts and secretory cells, bile ducts, gastrointestinal tract, bladder urothelial tissue, oral epithelium, esophagus, and cervical external epithelium (protein level) . It is expressed in specific regions of epidermal basal cells, nipple epidermis, and hair follicles. It is also found in some wall cells of the human umbilical vein and arteries, as well as in the smooth muscle of umbilical vessels. In structures containing dystrophin and spectroscopylin, muscle fibers aggregate in sarcomeres within the sarcoplasm of the sarcolemma. -
Subunit
Heterotetramer of two type I and two type II keratins. Interacts with PNN and the actin-binding domain of DMD. Interacts with HCV core protein
