title: Kinetics of the reaction between oxygen and haemoglobin bound to haptoglobin.
abstract: The kinetics of the reaction between O(2) and haemoglobin bound to haptoglobin 1-1 were investigated by the stopped-flow and temperature-jump techniques. The reaction, which follows second-order kinetics in the lower concentration range, becomes independent of O(2) concentration above about 150mum-O(2).
