Description
The QuickZyme Soluble Collagen Assay kit is a quantitative, dye-binding method for the measurement of all types of fibrillar collagen, in a fast and simple 96-well plate format.
Type
Colormetric Assay (Sirius Red Collagen Assay)
The QuickZyme Soluble Collagen Assay is based on binding of Sirius Red dye to collagen. Following binding of the dye, the collagen-dye complex precipitates, resulting in a colored pellet. This color can be released in an alkaline solution and then read with a microplate reader.

Application
Collagen is one of the main components of extracellular matrix. Dysregulation in collagen production results in pathologies such as fibrosis (too much collagen), or osteoarthritis (too little collagen). Therefore quantitative measurement of collagen production is important in many disease related studies.
The QuickZyme Soluble Collagen Assay measures various types of fibrillar collagen. The most abundant collagen types are collagen type I (skin, bone, vessels, connective tissue), type II (cartilage) and type III (skin, bone, connective tissue).
This assay is specific for collagen. After heating at 50°C the signal is lost, since the assay does not recognize denatured collagen (gelatin). The assay can be used to analyze soluble collagen or collagen that is solubilized by acetic acid alone or in combination with pepsin. The assay is intended for collagen analysis in conditioned cell culture media and cellular extracts. The assay is not affected by serum up to at least 10%.

Typical collagen standard curve in the range of 0.5 – 10 μg collagen/well (3.5 - 70 μg/ml; blank value 0.070).
