[S05] Sheep Anti-Human Apolipoprotein AII Antiserum

Importance

Apo AII comprises 25% of HDL. It exists in human plasma as a dimer of 2 identical chains of 77 amino acid residues, joined by disulfide. The molecular weight is reported to be 8.7 kDa for a single chain (Brewer et al., 1972).

Studies on mouse reported that apo AII may be proatherogenic (Warden et al., 1993); however, case-control study in the large European Prospective Investigation demonstrated that plasma Apo AII concentrations were strongly inversely correlated with CHD events (Birjmohun et al., 2007).
