Product Summary
The Quantikine Human TGF-beta 2 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure activated TGF-beta 2 in cell culture supernates, serum, and plasma. The Quantikine Human TGF-beta 2 Immunoassay contains CHO cell-derived recombinant human TGF-beta 2 and antibodies raised against the recombinant protein. The assay has been shown to quantitate the recombinant factor accurately. Results obtained using human TGF-beta 2 showed linear curves that were parallel to the standard curves obtained using the recombinant TGF-beta 2 kit standards. These results indicate that this kit can be used to determine relative mass values for natural human TGF-beta 2.
Precision
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision

Recovery
To assess recovery of the assay, samples of various matrices were spiked with three concentrations of TGF-beta 2, activated, and measured in the assay.

Linearity
To assess the linearity of the assay, samples were spiked with high concentrations of TGF-beta 2, activated and then serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
