Separation of human neutrophil granulocytes (red-filled) from lymphocytes (black-dashed) in flow cytometry analysis (surface staining) of human peripheral whole blood stained using anti-human CD222 (MEM-238) purified antibody (concentration in sample 2 µg/ml) GAM APC.

Flow cytometry surface staining pattern of human peripheral whole blood stained using anti-human CD222 (MEM-238) purified antibody (concentration in sample 2 µg/ml) GAM APC.

Anti-Hu CD222 Purified (clone MEM-238) works in WB application under non-reducing conditions. Western blotting analysis was performed on whole cell extracts (RIPA lysis buffer) of Jurkat, K562, Raji, and HeLa cell lines, mixed and heated (100°C, 5 min) with reducing and non-reducing SDS-loading buffer. Samples were resolved using 7% Tris-glycine SDS gel electrophoresis. Nitrocellulose membrane blot was probed with mouse IgG1 monoclonal antibody MEM-238 (1 µg/ml), followed by IRDye 800CW Goat-anti-Mouse IgG (green). Mouse anti-GAPDH monoclonal antibody FF26A conjugated with DyLight 680 (0.1 µg/ml), was used as the loading control (red). Multiplex fluorescent Western blot detection was performed. CD222 molecules were detected at ~250 kDa in all analysed cell lines.
