Carcinoembryonic antigen-related cell adhesion molecule 3 (CEACAM3), partial, human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 35-155aa. Protein Length: Extracellular Domain. Tag Info: N-terminal 6xHis-SUMO-tagged. Target Protein Sequence: KLTIESMPLS VAEGKEVLLL VHNLPQHLFG YSWYKGERVD GNSLIVGYVI GTQQATPGAA YSGRETIYTN ASLLIQNVTQ NDIGFYTLQV IKSDLVNEEA TGQFHVYQEN APGLPVGAVA G. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Major granulocyte receptor mediating recognition and efficient opsonin-independent phagocytosis of CEACAM-binding microorganisms, including Neissiria, Moxarella and Haemophilus species, thus playing an important role in the clearance of pathogens by the innate immune system. Responsible for RAC1 stimulation in the course of pathogen phagocytosis. Reference: "The microbial receptor CEACAM3 is linked to the calprotectin complex in granulocytes."
