The levels of VEGF-C measured by a quantitative, colorimetric, sandwich enzyme-linked immunosorbent assay in SSc serum samples (mean ± SD values = 1.25 ± 0.21 ng/mL) were similar to those detected in healthy control serum samples (mean ± SD values = 1.08 ± 0.14 ng/mL). The gene discussed is VEGFC; the disease is systemic sclerosis.
