Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Less than 1.0 EU/ug as determined by LAL method. Biological Activity: ?Measured by its binding ability in a functional ELISA. Immobilized Human CD93 at 2 µg/mL can bind Anti-CD93 recombinant antibody (CSB-RA865099MA1HU), the EC50 is 0.6639-1.173 ng/mL. ?Measured by its binding ability in a functional ELISA. Immobilized Human CD93 at 2 µg/mL can bind Human IGFBP7 (CSB-MP620956HUd9), the EC50 is 20.34-26.92 ng/mL. Form: Lyophilized powder. Buffer: Lyophilized from a 0.2 µm filtered 20 mM Tris-HCl, 0.5 M NaCl, 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: Receptor (or element of a larger receptor complex) for C1q, mannose-binding lectin (MBL2) and pulmonary surfactant protein A (SPA). May mediate the enhancement of phagocytosis in monocytes and macrophages upon interaction with soluble defense collagens. May play a role in intercellular adhesion.
