Application Abreviews Notes
WB 1/1000 - 1/10000. Predicted molecular weight: 54 kDa.
  • Application notes
    Is unsuitable for IP.
  • Target

    • Function

      May play a unique role in maintaining the normal corneal epithelial function. Together with KRT3, essential for the maintenance of corneal epithelium integrity.
    • Tissue specificity

      Cornea specific.
    • Involvement in disease

      Defects in KRT12 are a cause of Meesmann corneal dystrophy (MECD) [MIM:122100]; also abbreviated 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.
    • Sequence similarities

      Belongs to the intermediate filament family.

    Customer reviews and Q&As


    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 human which could be conjugated to FITC using one of our EasyLink conjugation kits, like ab102885.



    For cytokeratin 12, we do not carry any antibodies that have been tested in flow cytometry. However, if you would like to test ab124975 or ab113039 in FC, we could offer you a discount on a future purchase if you purchase, test, and submit an Abreview on the product (the discount is worth the price you pay for the antibody).

    For p63, we have an antibody conjugated to DyLight 488 that works in ICC/IF with human cells, ab139929. Again, if you would like to test this antibody in FC, we could offer you a future discount. https://www.abcam.com/p63-antibody-epr5701-dylight-488-ab139929.html

    For BCRP/ABCG2, we have 4 antibodies tested in FC, but non are conjugated to a fluorophore: ab24115, ab24114, and ab72788, and ab95692 (conjugated to biotin). You could use the purified antibody ab72788 with one of our conjugation kits to directly conjugate a fluorophore to the antibody.

    I hope this information helps. If you are interested in testing any of the antibodies as listed above, please let me know and I will set you up in our system.
