Type III Collagen provides structure and strength to connective tissue, is found many places in the body, especially skin, lung, intestinal walls and the walls of blood vessels. Collagen III is initially produced as procollagen, a protein consisting of three pro-alpha1(III) chains that form the triple-stranded, rope-like molecule. After being synthesized, the procollagen molecule is modified by the cell. Enzymes modify the amino acids lysine and proline in the protein strands by adding chemical groups that are necessary for the strands to form a stable molecule and then later to crosslink to other molecules outside the cell. The Type III procollagen molecules are released from the cell and are processed by enzymes that clip small segments off either end of the molecules to form mature collagen. The mature collagen molecules assemble into fibrils. Cross-linking between molecules produces a very stable fibril, contributing to collagen’s tissue strengthening function.
Type III Collagen is typically used as a thin coating on tissue culture surfaces or as a control. 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 III collagen may be used to culture a variety of cell types.

The Type III collagen undergoes an enzyme step in the purification process, resulting in Atelocollagen.
The purity is determined using an interrupted gel electrophoresis as seen in this report:

This video explains how to coat dishes using collagen. Collagen allows for better cell attachment, growth and proliferation.
The best way to help your collagen adhere to a glass coverslip is to first coat the coverslip with Poly-L-Ornithine (#5058-50ML) or Poly-L-Lysine (#5048-50ML). Then coat the coverslip with your Type I collagen (PureCol, #5005-100ML).
