evidence: Tumour reoxygenation after intratumoural hydrogen peroxide (KORTUC) injection: a novel approach to enhance radiosensitivity [...] Serial dilutions of hydrogen peroxide (#H1009, Sigma Aldrich, UK) were prepared in complete cell culture medium (0–9.6 mM). For intratumoural KORTUC injection, hydrogen peroxide (3% v/v, Stockport Pharmaceuticals, UK) was mixed with sodium hyaluronate gel (OSTENIL®, 20 mg sodium hyaluronate; AAH Pharmaceuticals, UK) and freshly prepared under sterile conditions to achieve a final clinical concentration of 150 mM (0.5% v/v).
