CD70 antigen (CD70), partial, human, recombinant

Organism: Homo sapiens (Human). Source: Mammalian cell. Expression Region: 39-193aa. Protein Length: Partial. Tag Info: N-terminal hFc-tagged. Target Protein Sequence: QRFAQAQQQL PLESLGWDVA ELQLNHTGPQ QDPRLYWQGG PALGRSFLHG PELDKGQLRI HRDGIYMVHI QVTLAICSST TASRHHPTTL AVGICSPASR SISLLRLSFH QGCTIASQRL TPLARGDTLC TNLTGTLLPS RNTDETFFGV QWVRP. 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: Cytokine which is the ligand for CD27. The CD70-CD27 pathway plays an important role in the generation and maintenance of T cell immunity, in particular during antiviral responses. Upon CD27 binding, induces the proliferation of costimulated T-cells and enhances the generation of cytolytic T-cells. Reference: Molecular and biological characterization of a ligand for CD27 defines a new family of cytokines with homology to tumor necrosis factor.Goodwin R.G., Alderson M.R., Smith C.A., Armitage R.J., Vandenbos T., Jerzy R., Tough T.W., Schoenborn M.A., David-Smith T., Hennen K., Falk B., Cosman D., Baker E., Sutherland G.R., Grabstein K.H., Farrah T., Giri J.G., Beckmann M.P.Cell 73:447-456(1993).
