**Background of Itgax Recombinant Protein**
The Itgax gene encodes integrin alpha X (CD11c), a transmembrane protein that pairs with beta-2 integrin (CD18) to form the heterodimeric receptor αXβ2. This integrin is predominantly expressed on dendritic cells (DCs), a subset of macrophages, and other antigen-presenting cells, where it plays critical roles in cell adhesion, migration, and immune surveillance. CD11c serves as a defining marker for conventional DCs, making it invaluable for identifying and isolating these cells in immunological studies.
Recombinant Itgax protein is engineered using expression systems such as mammalian cells, insect cells, or *E. coli*, often fused with tags (e.g., Fc, His) to facilitate purification and detection. The production involves cloning the Itgax gene into expression vectors, followed by transfection, protein harvesting, and affinity chromatography. This approach ensures high purity and bioactivity, mimicking native CD11c’s functional properties.
Itgax recombinant proteins are widely used to study integrin-mediated signaling, DC biology, and interactions with ligands like fibrinogen or ICAM-1. They also aid in developing DC-targeted vaccines, cancer immunotherapies, and autoimmune disease models. By enabling *in vitro* analyses of receptor-ligand binding, immune cell activation, and intracellular signaling, these proteins offer a controlled alternative to animal-derived materials, reducing variability in experimental outcomes.
Overall, Itgax recombinant proteins are essential tools for dissecting immune mechanisms and advancing therapeutic strategies centered on dendritic cell function. Their applications span basic research, drug discovery, and biotechnology, underscoring their significance in immunology and translational medicine.
