The extent of expression of basement membrane component collagen IV may be correlated with the degree of differentiation of basement membrane producing neoplasma. Neoplastic cells of invasive carcinomas often lack a continuous basement membrane. in diagnostic histopathology antibodies to type IV collagen may help to distinguish between non-invasive (benign or in situ) and invasive lesions. Furthermore the antiserum is important in the the differential diagnosis of bullous lesions in dermatopathology.

Suitable for use in Immunohistochemistry. Other applications not tested.

Recommended Dilution:
Immunohistochemistry (Acetone fixed frozen sections, formaldehyde fixed, pepsin pretreated paraffin sections): 1:50-1:100 using the Indirect method. Dilute immediately before use with PBS or Tris.
Optimal dilutions to be determined by the researcher.
