Anti-Collagen I, alpha 1 propeptide Antibody is suitable for use in ELISA, Western Blotting and IHC. Specific conditions for reactivity should be optimized by the end user. Expect a band of approximately 180 kDa in size corresponding to collagen I alpha I polypeptide in human lung fibroblast extracts or other appropriate tissues or lysates. Collagen I alpha 1 propeptide antibody also works well for IHC on paraformaldehyde-fixed sections with a simple antigen-retrieval protocol (incubate slides for 20 minutes at 90
