  • Target

    • Function

      Stratified squamous epithelial basement membrane protein that forms anchoring fibrils which may contribute to epithelial basement membrane organization and adherence by interacting with extracellular matrix (ECM) proteins such as type IV collagen.
    • Involvement in disease

      Epidermolysis bullosa acquisita (EBA) is an autoimmune acquired blistering skin disease resulting from autoantibodies to type VII collagen.

    • Immunohistochemical staining of Collagen VII in human skin tissue sections with ab93350. Samples were fixed with formaldehyde and enzymatic antigen retrieval was performed with Proteinase K. Tissue was blocked with 1% BSA for 10 minutes at 21°C before ab93350 was added (1/250) for 2 hours at 21°C. A biotin conjugated goat anti-rabbit secondary was used at 1/250.

      See Abreview

    • Immunohistochemical staining of human skin tissue (frozen sections) labeling Collagen VII with ab93350. Samples were fixed using acetone and 3% BSA was used as blocking agent for 1 hour at room temperature. Samples were incubated with ab93350 for 1 hour at 1/200 dilution. An Alexa Fluor-488 rabbit polyclonal was used as a secondary antibody.

    Thank you for your inquiry.

    I heard back from the lab that our anti-Collagen VII antibody is specific only for helical domains (collagen VII fragments). The non-collagen fragments obtained after pepsin digestion are broken and cannot be detected.

    I'm not sure if any of our Collagen VII antibodies will suit your needs, but take a look at ab80790 as this one has quite a few references and has been used for cell staining.
    I hope this information helps. Please contact us with any other questions.

    Thank you for your enquiry.

    I can confirm that any publications that we are aware of will be listed on the datasheet. We have a dedicated team who spend time reviewing the literature to find articles that have used our products. However, in many cases, regrettably we do not have access to all the articles mentioning our products, or subscriptions to all the journals that publish them. I'm sorry there are none to provide on this occasion for ab93350 and ab96885.

    Should you have any further questions, please do not hesitate to contact us.
