Thanks for your inquiry.
Usually we suggest you test the sample types mentioned in the kit manual. You can do a pretest first if you want to test bone extract sample.

Hydroxyproline is small molecule and it is the same in different species. There are 3 reasons why we have species specific elisa kits.
1. For different species, the sample matrix is different and the characteristics of antibody used in the kits are also different.
2. The methods of these 3 kits are different. Human kit and mouse kit are based on double antibody sandwich method.
When the kit was developed, it was designed to mimic the presence of hydroxyproline in vivo. It can detect polymerized form. (including the polymerized form with other proteins and self-polymerization form). For human kit, capture antibody is mouse monoclonal antibody and detection antibody is goat polyclonal antibody; For mouse kit, capture antibody is rat monoclonal antibody and detection antibody is goat polyclonal antibody.
Rat kit is based on competitive method. The plate is coated with mouse monoclonal antibody. HRP conjugated HYP competes with the HYP in the sample. The kit can detect the endogenous total HYP, including free form and polymerized form.
3. The reason why different kits use different methods is based on a variety of factors. You can choose the appropriate kit to avoid matrix problems.
Pls let me know if you have any further questions. Thank you.
