Human CD70 (TNFSF7) is the ligand for CD27 (TNFRSF7) and is notably absent on resting lymphocytes. CD70 is expressed after activation on about 20% of T cells and on about 70% of B cells. Recombinant CD70-muCD8 binds to cell surface CD27 on human peripheral blood leukocytes. Molecular Structure: A soluble molecule consisting of the extracellular domain (167aa) of murine CD8 alpha fused to 146 (c-term) amino acids of the extracellular domain of human CD70, with a predicted monomeric weight of 34.8kD. Extracellular mature murine CD8alpha: (28)KPQAPEL....GLDFACD(194), Linking amino acids: GT, extracellular human CD70: (48)LPLESL....VQWVRP(193). Applications: Suitable for use in ELISA and Flow Cytometry. Other applications not tested. Recommended Dilution Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4C. For long-term storage, aliquot and store at 4C. Do not freeze. Aliquots are stable for at least 6 months. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
