  • 组织特异性Cornea specific.
  • 疾病相关Defects in KRT3 are a cause of Meesmann corneal dystrophy (MECD) [MIM:122100]; also abbreviated as MCD and known as juvenile epithelial corneal dystrophy of Meesmann. MECD is an autosomal dominant disease that causes fragility of the anterior corneal epithelium. Patients are usually asymptomatic until adulthood when rupture of the corneal microcysts may cause erosions, producing clinical symptoms such as photophobia, contact lens intolerance and intermittent diminution of visual acuity. Rarely, subepithelial scarring causes irregular corneal astigmatism and permanent visual impairment. Histological examination shows a disorganized and thickened epithelium with widespread cytoplasmic vacuolation and numerous small, round, debris-laden intraepithelial cysts.

  • Overlay histogram showing A431 cells stained with ab77869 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab77869, 2µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

  • ab77869 staining Cytokeratin 3 (red) in transfected Ptk2 cells by Immunocytochemistry/ Immunofluorescence.

    Cells were co-transfected in quadruplicate with wild-type, mutant, or a 1:1 mixture of wild-type and mutant K12 expression plasmids along with a wild-type K3 expression construct. After 72 hours, cells were fixed with 3% paraformaldehyde for 20 minutes, before being incubated with primary antibody. Nuclei were stained with DAPI (blue).

Thank you for your inquiry and your interest in our products.

I searched our catalogue and we currently do not have a cytokeratin 3 antibody that is directly conjugated. We do carry ab77869, which has been tested in FC with rabbit, cow and hu...
