Rat beta-CTx (Beta Crosslaps) ELISA Kit (RTES00981)

This competitive colorimetric ELISA from Assay Genie is intended for measuring rat beta-CTx (beta crosslaps) in serum, plasma and other biological fluids, and the manufacturer also describes its use with cell culture supernatants.

Quoted performance specifications are a sensitivity of "75 pg/mL", a detection range of "125-8000 pg/mL" and recovery of "80%-120%". The assay time is listed as "2 h 30 min" and the sample volume as "50 μL"; storage is stated as "2-8°C".

The manufacturer reports intra-assay CV values of "5.8%", "5.32%" and "5.59%" and inter-assay CV values of "6.91%", "6.67%" and "6.45%". The kit recognises rat β-CTx, with no significant cross-reactivity or interference between rat β-CTx and analogues reported. Beta-crosslaps are described as markers of bone resorption that offer insight into bone turnover and bone health.
