Isotype

Mouse IgG1

Specificity

The antibody MEM-240 recognizes an extracellular epitope between amino acids 698-1262 of CD222 (IGF2 receptor), a ubiquitously expressed 250 kDa multifunctional type I transmembrane protein. The majority of CD222 is found in the late endosomal/prelysosomal compartment, 5-10% in the plasma membrane and the truncated (220 kDa) form of CD222 is present in human and bovine serum.

Antigen description

CD222 (CIMPR, cation-independent mannose 6-phosphate receptor; IGF2 receptor) is a ubiquitously expressed 250 kDa transmembrane protein. No more than 10% of CD222 is present on the cell surface where it serves as a multifunctional receptor. Intracellular (major) fraction of CD222 is involved in transport of newly synthesized lysosomal enzymes modified by mannose 6-phosphate from Golgi apparatus to lysosomes. The cell surface CD222 binds and internalizes exogeneous mannose 6-phosphate-containing ligands. Importantly, CD222 is crutial for internalization and degradation of insulin-like growth factor 2, thus controling cell growth. CD222 also complexes CD87 (urokinase-type plasminogen-activator receptor), plasminogen and latent TGF-beta, last but not least CD222 serves as a receptor for heparanase and even for Listeria.

Flow cytometry surface staining pattern of human peripheral whole blood stained using anti-human CD222 (MEM-240) purified antibody (concentration in sample 3 μg/ml) GAM APC.

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-240) purified antibody (concentration in sample 3 μg/ml) GAM APC.

Anti-Hu CD222 Purified (clone MEM-240) 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% SDS-PAGE gel.

Nitrocellulose membrane blot was probed with mouse IgG1 monoclonal antibody MEM-240 (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.
