Anti-Cytokeratin 3+12抗体[AE5] (ab68260)


  • 产品名称Anti-Cytokeratin 3+12抗体[AE5]
  • 描述
    小鼠单克隆抗体[AE5] to Cytokeratin 3+12
  • 特异性This antibody recognizes the 64kD polypeptide (cytokeratin 3) and 55 kDa polypeptide (cytokeratin 12) of rabbit corneal epithelium. It also recognizes bovine snout and lip epithelium, as well as a rabbit corneal cell line. The clone number has been updated from (2Q1040) to (AE5) both clone numbers name the same antibody clone.

  • 相关性Cytokeratin 3 is a member of the intermediate filament family of proteins and is a heterotetramer of two type I and two type II keratins. Keratin 3 is specifically expressed in the corneal epithelium with family member KRT12. Cytokeratin 12 encodes the type I intermediate filament chain keratin 12, expressed in corneal epithelia. Defects in KRT3 and KRT12 are a cause of Meesmann corneal dystrophy (MCD), an autosomal dominant disease that causes fragility of the anterior corneal epithelium. Symptoms occur in adulthood and include rupture of the corneal microcysts that may lead to photophobia, contact lens intolerance and intermittent diminution of visual acuity. Defects in KRT12 are a cause of juvenile epithelial corneal dystrophy of Meesmann (MCD)

  • Immunofluorescence analysis of rabbit cornea cells, staining Cytokeratin 3+12 with ab68620.

    Cells were fixed with paraformaldehyde, permeabilized with 0.1% Triton X-100 and blocked with 3% BSA for 1 hour at 20°C. Samples were incubated with primary antibody (1/50 in 3% BSA in PBST (0.5% Tween 20)) for 12 hours at 4°C. An AlexaFluor®594-conjugated goat anti-mouse polyclonal IgG (1/100) was used as the secondary antibody.

  • Immunofluorescent analysis of human ocular surface squamous cell carcinoma tissue, labeling Cytokeratin 3+12 with ab68260. Samples were fixed in 4% paraformaldehyde and blocked wuth 4% BSA with 0.1% Triton X-100. Incubation with ab68260 (diluted 1/50) overnight at 4°C. Samples were then incubated with an Alexa Fluor 488-conjugated secondary antibody for 1 hour, and counterstained with DAPI to visualize nuclei.
