Background
The extent of expression of the basement membrane component type IV collagen 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 differential diagnosis of bullous lesions in dermatopathology.

Source
This polyclonal type IV collagen antibody is a rabbit polyclonal antibody. The rabbits were immunized with isolated human type IV collagen. The immunogen has been isolated from human placenta.

Product
Each vial contains 250ul Rabbit polyclonal antiserum including 0.09% sodium azide

Specificity
Polyclonal type IV collagen recognizes the extracellular – basement membranes.

Applications
Polyclonal type IV is useful for immunoblotting, immunocytochemistry on fixed cells (methanol fixation) and immunohistochemistry on frozen tissues (fixed in methanol, aceton or 1% paraformaldehyde) when using a PBS buffer containing 0.1 mM CaCl2 and 0.1 mM MgCl2. For immunohistochemistry on paraffin tissue the sections should be pretreated with 1 mg/ml pepsin in 0.01 N HCl for 30 minutes at room temperature. Optimal antibody dilution should be determined by titration; 1:25 – 1:100 for immunohistochemistry with avidin-biotinylated Horseradish peroxidase complex (ABC) as detection reagent, and 1:100 – 1:1000 for immunoblotting applications.

Storage
The antibody is shipped at ambient temperature and may be stored at +4°C. For prolonged storage prepare appropriate aliquots and store at or below -20°C. Prior to use, an aliquot is thawed slowly in the dark at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance or the concentration of the product.

Shipping Conditions: Ship at ambient temperature.
