More measured growth factors. By the numbers.
Follitrix was evaluated against a reference GFC kit using quantitative ELISA analysis. Across all four growth-factor markers (PDGF-BB, IGF-1, EGF and VEGF-A), Follitrix showed a higher measured concentration in the tested samples.
The comparison uses the final concentration tables, excludes out-of-range values from averages, and uses the most reliable dilution for each analyte.
Follitrix measured higher across all four markers.
Reference-kit average is shown as 100% (the white marker). The Follitrix bar shows the measured concentration relative to that reference.
Relative concentration index
| Analyte | Reference = 100% | Follitrix | Measured difference |
|---|---|---|---|
| PDGF-BB | 100.0% | 141.8% | +41.8% |
| IGF-1 | 100.0% | 136.3% | +36.3% |
| EGF | 100.0% | 112.8% | +12.8% |
| VEGF-A | 100.0% | 109.1% | +9.1% |
