Application

  • Direct Assays: Hydroxyproline and collagen in biologic and cosmetic samples.

Key Features

  • Safe. Our hydroxyproline assay uses an improved perchlorate-free chemistry.
  • Sensitive and accurate. Uses 20 µL sample. Linear detection range 0.5 µg/mL to 50 µg/mL hydroxyproline in 96-well plate assay.
  • Convenient. Collagen can be hydrolyzed in Eppendorf tubes, and final incubation can be performed at 37°C.

More Details

  • HYDROXYPROLINE is a unique modified amino acid that is found exclusively in several animal proteins, the most prevalent of which is collagen. Collagen is a key structural protein of the extracellular matrix and is common in connective tissues due to its incredible strength. Because of its role as a key structural protein in animals collagen is crucial for many medical applications, such as tissue transplantation and scaffolding for complex cell cultures. Collagen is also used in the beauty industry, as it can be supplemented to increase tissue rigidity, resulting in skin that appears more youthful. BioAssay Systems’ Hydroxyproline assay kit delivers a safe, simple, and sensitive means to quantify hydroxyproline in samples. In the first step of this procedure, hydroxyproline in the sample is oxidized to a pyrrole ring. This compound then reacts with a dye reagent to yield a pink product that can be measured at 560 nm. Hydroxyproline exists almost exclusively in collagen, so hydroxyproline content can be used as a proxy for collagen content.

How do I hydrolyze solid collagen samples(cartilage, tendon, etc.)?

Dessicate sample in a drying oven until all water has been removed(Can measure wet weight, but dry is more accurate). Add 50 µL 6N NaOH for every 150 mg of sample to be hydrolyzed in an Eppendorf tube. Heat in a heat block at 100°C for 1-2 hours. Allow tube to cool. Add equivalent 10N HCl to neutralize NaOH. Add a volume of deionized water equal to the amount of NaOH and HCl added. (A detailed hydrolysis procedure is in the product datasheet).

Do I need to hydrolyze the hydroxyproline standard?

We have found that the hydroxyproline standards and blank are very similar whether or not they undergo hydrolysis. Therefore, the kit does not require hydrolysis treatment of the hydroxyproline standard.

Can I run the final incubation at a different temperature?

The incubation can be set to 45°C for 50 minutes. The protocol states to use 37°C because then it can be run in a plate reader or a tissue culture incubator. Some plate readers may not heat to 45°C.
