Product Description

This Type IV Collagen is isolated from human placenta and is purified using a multi-step process.  The product is supplied as a sterile, lyophilized powder containing 5 mg of Type IV collagen per vial.

Type IV Collagen is the primary collagen found in the extracellular basement membranes separating a variety of epithelial and endothelial cells.  It is a major component of the dermal-epidermal junction where it is mostly found in the lamina densa.  It is a heterotrimeric molecule containing two Alpha 1-like and one Alpha 2-like chains.

Type IV Collagen is typically used as a thin coating on tissue culture surfaces.  Specific instructions are found in the Directions for Use. This product is generally used in vitro as a substrate scaffold to enhance cell attachment, adherence and proliferation. Type IV collagen may be used to culture epithelial, endothelial, muscle, nerve and many other cell types. Additionally, this product is suitable for use as a substrate for collagenase assays and positive controls.

Coating Procedure

  1. Reconstitute the 5 mg vial with 5 ml of cold, sterile 0.25% acetic acid and mix by pipetting up and down several times.  Allow to mix at 2 to 8°C  overnight.  Note: The resulting solution will be slightly hazy.   If there are some insoluble materials present and you wish to remove it, aseptically centrifuge the material for approximately 2 minutes at 3000 RPM .
  2. Dilute the product to desired concentration with sterile 0.25% acetic acid.  A typical final coating concentration may be 10 to 100 µg/ cm2.  Testing will likely be required to determine optimal concentrations required for different cell culture systems.
  3. Add appropriate amount of diluted product to culture surface.
  4. Incubate at room temperature, covered, for 1-2 hours. Aspirate any remaining material. Alternatively, incubate at room temperature until surface is dry.
  5. Rinse coated surface carefully with a sterile balanced salt solution. Avoid scratching surfaces.
  6. Aspirate remaining material from coated surface.
  7. Coated culture vessels are now ready to use.  The coated culture vessels may be stored at 2 to 10°C.

Product Q & A

The Type IV collagen undergoes an enzyme step in the purification process, resulting in Atelocollagen.
