Collagen type I (COLI) is regarded as one of the abundant molecules that is present within the body. They are vital in connective tissues, bones and skin. A key structural composition for many tissues, essentially an interstitial matrix that is organised into fibrils. to form collagen fibers. A single collagen molecule has three structural components: a protein domain, a triple helical domain and an amino acid-rich domain. The COLI domain is composed of amino acids arranged in three helices around the nonhelical region that contains most of the peptide bonds. The tropheil olefin is used to bond two opposite repeat units together, and his is known as the only hydrophobic bonding site within the molecule.
Collagen type I is synthesised as a pro-collagen precursor that is made up of a C-terminal pro-peptide, a central collagen domain, and an N-terminal pro-peptide. The pro-collagen chains can translocate to the lumen of the rough endoplasmic reticulum. This is followed a process of folding and post-translational modification within the ER, eventually the pro-collagen molecules are taken up by the Golgi apparatus and secreted out of the cell. The central domain of pro-collagen can be cleaved, resulting in either a procollagen or a metalloproteinase-resistant peptide. This is followed by ERAD, whereby the newly formed peptide is taken up into the lumen of the Golgi and transported. After transcytosis in a process called retrograde transport, pro-collagen reaches its destination: the extracellular matrix (ECM).
Human collagen type I ELISA kit is designed for analysing levels of collagen type I (COLI) present in human serum, biological fluids, tissue homogenates and plasma samples.
All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.
