Human CCR8 protein (Cat# PME101091)produced from HEK293 cells was tested by SDS-PAGE and Coomassie blue staining (Left), and ELISA binding assay with anti-CCR8 biosimilar antibody (Right, Cat# BME100063), after freshly made and stored in lyophilized format at 37℃ for 24h, 48h and 72h respectively.
Human CD47 protein(Cat# PME100008) was produced from HEK293 cells and tested by ELISA binding assays with Anti-CD47 neutralizing antibody (Left, clone Hu5F9-G4, Cat# BME100001), and its native ligand Human SIRPα protein (Right, Cat# PME100009).
Similar levels of purity and bioactivity of human CCR8 protein (Cat# PME101091) from different purification lots were detected by SDS-PAGE and Coomassie blue staining (Left) and ELISA binding assay (Right).
