MiRNA profiles in blood plasma from mother-child duos in human biobanks and the implication of sample quality: Circulating miRNAs as potential early markers of child health
Fig 2
Spectrophotometric analysis of plasma to assess the degree of hemolysis from oxyhemoglobin absorbance at 414 nm.
Absorbance in plasma was measured for (A) cord blood (n = 38), (B) maternal blood (n = 38), and a hemolyzed reference sample (in red). Average absorbance at 414 nm for the plasma samples from cord and maternal blood was 0.18 ±0.015 (range: 0.05–0.44) and 0.25 ±0.020 (range: 0.03–0.48), respectively. Absorbance at 414 nm for the hemolyzed reference sample was 1.12.
