Fig. 4From: Stability of pro- and anti-inflammatory immune biomarkers for human cohort studiesPro- and anti-inflammatory cytokines (a), acute phase proteins and inflammatory biomarkers (b) in serum, as well as plasma, remain stable despite repeated freeze/thaw cycles but the values obtained from the two sources are often distinct. Serum and plasma were obtained from a set of individuals and analysed both immediately and following five freeze/thaw cyclesBack to article page
