简介
The S100A9 protein is a calcium and zinc binder that plays a critical regulatory role in inflammation and immune responses. Its diverse functions include induction of neutrophil chemotaxis, adhesion, enhanced bactericidal activity through SYK, PI3K/AKT and ERK1/2 activation, and promotion of phagocytosis. S100A9 Protein, Human (His) is the recombinant human-derived S100A9 protein, expressed by E. coli , with N-6*His labeled tag.

稳定性测试
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

背景信息
Heme oxygenase-1 (HO-1) is an enzyme that plays a pivotal role in the catabolism of heme, leading to the production of biliverdin, carbon monoxide, and free iron. It is a key player in various physiological processes, including oxidative stress response, apoptosis, and inflammation, making it a crucial target for therapeutic interventions in various diseases. Research has increasingly focused on the upregulation of HO-1 as a cytoprotective mechanism, particularly in conditions such as ischemia-reperfusion injury, neurodegenerative disorders, and cardiovascular diseases. The enzyme's expression is often induced by various stressors and cytokines, highlighting its role as a regulatory protein in cellular defense mechanisms. Investigations into recombinant HO-1 protein have allowed scientists to explore its functional properties, potential therapeutic applications, and the molecular pathways involved in its action. Given its antioxidant and anti-inflammatory properties, recombinant HO-1 is being studied for its potential in the treatment of diseases characterized by oxidative stress and inflammation. Furthermore, understanding the regulatory mechanisms of HO-1 expression and activity may lead to novel strategies for enhancing its protective effects in clinical settings. Thus, the study of HO-1, particularly in its recombinant form, holds significant promise for the development of innovative therapeutic approaches aimed at mitigating tissue damage and improving outcomes in various pathological conditions.
