Figure 4From: Haptoglobin inhibits phospholipid transfer protein activity in hyperlipidemic human plasmaEffect of Haptoglobin addition on PLTP activity (5 min) in hyperlipidemic plasma. The equivalent of 100% of basal haptoglobin levels was added to each plasma sample and PLTP activity was measured as described previously (n = 6, p < 0.05).Back to article page
