Specificity
This antibody recognises human heme oxygenase-1 (HO-1), a 288 amino acid enzyme with a crucial role in heme catabolism, cleaving the heme ring to form biliverdin which is further processed to form bilirubin by a reductase enzyme. HO-1 activity is highest in the spleen where it is involved in the processing of senescent erythrocytes. HO-1 expression can be increased during cellular stress, including heat shock. Baseline levels of expression are high in certain tissues, including spleen and liver. Enriched enzyme preparations are recommended for experimental analysis.
