Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.
線性度:
To assess the linearity of the assay, samples were spiked with high concentrations of mouse WNT2 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

標準曲線:
These standard curves are provided for demonstration only. A standard curve should be generated for each set of samples assayed.
a. The active ingredient of the stop solution and its concentration ? b. The type, concentration, and state (liquid/lyophilized) of the preservatives used. Please name the components with preservatives ? c. If the components are lyophilized, what is the concentration prior to reconstitution (i.e. mass of preservative used/ total mass of lyophilized vial contents)? d. Expression host of the standards ? e. Which components have H202 ( including other forms of peroxide such as urea hydrogen peroxide) ?Please list with the concentration of H202/peroxide in each, if any?
A:
Thanks for your inquiry! CSB-EL026133MO Stop solution is 4N sulfuric acid. Preservatives is liquid proclin 300(1:3000); Standard is NS0-derived recombinant protein. It is lyophilized powder. The concentration after reconstitution is 1000pg/mL(pls refer to Page 9 in the manual); The kit doesn't contain H2O2. Pls let me know if you have any further questions. Thank you.
Q:
Just to clarify, Preservatives (proclin 300) is included only in the lyophilized standard ? Also, please confirm that the only preservative is proclin 300? If not, please let me know the names and concentrations
A:
All components contain preservatives?(proclin?300) except wash?buffer、TMB?Substrate and Stop?Solution.
Ligand for members of the frizzled family of seven transmembrane receptors. Functions in the canonical Wnt/beta-catenin signaling pathway. Functions as upstream regulator of FGF10 expression. Plays an important role in embryonic lung development. May contribute to embryonic brain development by regulating the proliferation of dopaminergic precursors and neurons.
