The CEACAM3 protein is a key granulocyte receptor that effectively orchestrates the opsonin-independent phagocytosis of CEACAM-bound microorganisms such as Neisseria spp., Moraxella spp., and Haemophilus spp. This role places CEACAM3 at the forefront of pathogen clearance in the innate immune system. CEACAM3 Protein, Human (His-SUMO) is the recombinant human-derived CEACAM3 protein, expressed by E. coli , with N-6*His, N-SUMO labeled tag.
