TGF-b1 (ELISA)
Use
TGF-ß1 (Transforming Growth Factor Beta 1) is a multifunctional cytokine involved in various cellular processes, such as immune regulation, cell differentiation, and fibrosis. The TGF-ß1 ELISA is used for detecting TGF-ß1 levels in serum. The assay provides quantitative measurements of TGF-ß1 by using a substrate reaction that produces a detectable signal proportional to the concentration of TGF-ß1.
Special Instructions
This test is available for use in clinical trials or research purposes only. Stated turn-around-times (TATs) are for clinical use only and subject to change based on biopharma protocol requirements. Final TATs will be specified in the biopharma study contract.
Limitations
RUO - Research Use Only; not for clinical diagnostic use. Improper specimen labeling, insufficient sample volume, or specimens beyond stability are causes for rejection. Specimen handling and stability are critical to test performance.

Collection Instructions
Blood should be drawn into the SST tube, which contains a gel separator that helps to separate the serum from blood cells after centrifugation. The tube should be allowed to clot at room temperature for approximately 30 minutes and then centrifuged.
Storage Instructions
Whole blood in SST: 2°C to 8°C. Refrigerated serum: 2°C to 8°C. Frozen serum: ≤ -15°C.
Causes for Rejection
Improper specimen labeling; Insufficient sample volume; Specimens beyond stability

| Temperature | Period |
|---|---|
| Room Temperature | 48 hours |
| Refrigerated | 48 hours |
| Frozen | long term |
