The Human Collagen Type I (CI) ELISA kit is used to measure type I collagen levels from human cells.



Collagen Type I (CI) is the most abundant protein and is found in the skin, connective tissue, tendons, ligaments, cornea, invertebral discs and bone. It is encoded by the genes COL1A1 and COL1A2 and is formed inside (along the rough endoplasmic reticulum) and outside (by procollagen peptidase and bound by fibronectin and integrin) the cell. Individual collagen molecules are cross-linked to one another within these fibrils. The formation of cross-links results in very strong type I collagen fibrils, which are found in the spaces around cells.  Collagen Type I is involved in many human diseases such as fibrosis, osteoporosis, cancer and atherosclerosis.

How It Works

How It Works: 

The competitive assay (EIA) is a colormetric based immunoassay utilizing a biotinylated polyclonal antibody to Collagen Type I and purified human collagen type I as an antigen. Bound Collagen Type I coated on the surface of the microwells competes for the biotinylated antibody with free antigen in the standard and samples. This system creates an inverse relationship between OD values and concentration: the higher the OD value, the lower the concentration of collagen type I in the sample.
