Our Anti-Collagen 1, alpha 1 propeptide primary antibody from PhosphoSolutions is rabbit polyclonal. It detects human, mouse, and rat Collagen 1, alpha 1 propeptide and is antigen affinity purified. It is great for use in WB, IHC.
Western blot of rat lung lysate showing specific immunolabeling of the ~180 kDa collagen 1.
Collagen is an extracellular matrix protein that serves as a scaffold defining the shape and mechanical properties of many tissues and organs including skin, tendon, artery walls, fibrocartilage, bone and teeth. Type 1 collagen is the most abundant protein in mammals. Collagens are synthesized with N-terminal and C-terminal propeptides that are cleaved during maturation and secretion. After cleavage of the propeptides, the most N-terminal and C-terminal remaining sequences are known as telopeptides. Mutations in the collagen 1, alpha 1 gene (COL1A1) are known to cause osteogenesis imperfecta (aka brittle bone disease) (Byers 1989). Furthermore, mutations found in the first 90 residues of the helical region of alpha 1 collagen have been implicated in the prevention or delayed removal of the procollagen N-propeptide leading to a combined osteogenesis imperfecta and Ehlers-Danlos syndrome (EDS) phenotype (Cabral et al., 2005)

COL1A1
180 kDa
Synthetic peptide corresponding to amino acid residues specific to the human collagen 1, alpha 1 propeptide conjugated to keyhole limpet hemocyanin (KLH).
Recommended that the undiluted antibody be aliquoted into smaller working volumes (10-30 uL/vial depending on usage) upon arrival and stored long term at -20° C or -80° C, while keeping a working aliquot stored at 4° C for short term. Avoid freeze/thaw cycles. Stable for at least 1 year.

WB: 1:1000
IHC: 1:100
Unconjugated
Specific for endogenous levels of the propeptide portion of the ~180 kDa collagen I alpha 1 polypeptide in human lung fibroblast extract. The antibody also works well for immunohistochemistry on paraformaldehyde-fixed sections with a simple antigen-retrieval protocol (incubate slides for 20 minutes at 90º C in 10 mM sodium citrate (pH 6.0)/ 0.1 % Tween-20). Note that in paraffin sections of formaldehyde-fixed fibrotic mouse lung tissue, the antibody recognizes collagen I molecules that are still associated with the cells in which they were synthesized.
