Product Summary
The Quantikine Human TGF-beta 1 Immunoassay is a 4.5 hour solid phase ELISA designed to measure TGF-beta 1 in acid activated cell culture supernates, serum, plasma, and urine. It contains recombinant human TGF-beta 1 expressed by CHO cells and has been shown to quantitate the recombinant factor accurately. Results obtained using natural TGF-beta 1 showed linear curves that were parallel to the standard curves obtained using the recombinant kit standards. These results indicate that this kit will provide accurate quantitation for both recombinant and natural human TGF-beta 1.

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
The recovery of TGF-beta 1 spiked to levels throughout the range of the assay followed by activation was evaluated.
| Sample Type | Average % Recovery | Range % |
| Cell Culture Supernates (n=4) | 99 | 86-115 |
| Urine (n=3) | 96 | 88-100 |

Linearity
To assess the linearity of the assay, activated samples containing and/or spiked with high concentrations of TGF-beta 1 were diluted with Calibrator Diluent and then assayed.

- Background
- TGF-beta Family Ligands
- Transforming Growth Factor Beta 1, 2, and 3 (TGF-beta 1, TGF-beta 2, and TGF-beta 3) are highly pleiotropic cytokines that virtually all cell types secrete. TGF-beta molecules are proposed to act as cellular switches that regulate processes such as immune function, proliferation, and epithelial-mesenchymal transition. Targeted deletions of these genes in mice show that each TGF-beta isoform has some non-redundant functions: TGF-beta 1 is involved in hematopoiesis and endothelial differentiation; TGF-beta 2 affects development of cardiac, lung, craniofacial, limb, eye, ear, and urogenital systems; and TGF-beta 3 influences palatogenesis and pulmonary development. The full range of in vitro biological activities of TGF-beta 5 has not yet been explored. However, TGF-beta 1, TGF-beta 2, TGF-beta 3, and TGF-beta 5 have been found to be largely interchangeable in an inhibitory bioassay, and it is anticipated that TGF-beta 5 will show a spectrum of activities similar to the other TGF-beta family members. To date, the production of TGF-beta 5 has only been demonstrated in Xenopus.TGF-beta ligands are initially synthesized as precursor proteins that undergo proteolytic cleavage. The mature segments form active ligand dimers via a disulfide-rich core consisting of the characteristic 'cysteine knot'. TGF-beta signaling begins with binding to a complex of the accessory receptor betaglycan (also known as TGF-beta RIII) and a type II serine/threonine kinase receptor termed TGF-beta RII. This receptor then phosphorylates and activates a type I serine/threonine kinase receptor, either ALK-1 or TGF-beta RI (also called ALK-5). The activated type I receptor phosphorylates and activates Smad proteins that regulate transcription. Use of other signaling pathways that are Smad-independent allows for distinct actions observed in response to TGF-beta in different contexts.
