Intra-assay (n=8) ≤ 7%, Inter-assay (n=6) ≤ 10%
The mean recovery of recombinant Sclerostin in human serum samples (n=6) is 94%.
The mean dilution linearity of endogenous Sclerostin in human serum samples (n=4) is 110% for dilution factors 1+1, 1+3, 1+7.
The mean dilution linearity for recombinant Sclerostin in human serum samples (n=3) is 98% for dilution factors 1+1, 1+3.
The assay does not detect Noggin.
The assay does not detect Wise (SOSTDC1).
Species cross reactivity:
Rat, mouse: The assay does not detect rat or mouse Sclerostin.
Primates: The sequence homology of human Sclerostin to various primate species is >95%. It is likely that the assay can be used for these species. Internal validations have not been carried out. However, data from other laboratories show positive results.
Serum values from apparently healthy individuals:
Median (serum, n=411): 24.14. pmol/l.
It is recommended to establish the normal range for each laboratory.
Principle of the assay:
Manual ELISAs - easily adaptable for automation!
