Western blot analysis was performed on whole cell extracts (30 ug lysate) of Ramos (Lane1), A-431 (Lane2), K562 (Lane 3) and Raji (Lane4). The blots were probed with Anti-CD2 Mouse Monoclonal Antibody (Product# MA0200, 0.5-2 ug/ml) and detected by chemiluminescence using Goat anti-Mouse IgG (H+L) Secondary Antibody, HRP conjugate (Product # 626520, 1:4000 dilution). A 40 kDa band corresponding to CD2 was observed across cell lines tested expect for K562. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 12 % Bis-Tris gel (Product # NP0341BOX), XCell SureLock™ Electrophoresis System (Product # EI0002), and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® 2 Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary Antibody using iBind™ Flex Western Starter Kit (Product# SLF2000S). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

MA0200 targets CD2 in FACS, IA, IP, and WB applications and shows reactivity with Human samples. This antibody does not react with rat tissue in Western blot applications.
The MA0200 immunogen is human LFA-2 (CD2).
MA0200 detects CD2 which has a predicted molecular weight of approximately 37 kDa.
CD2 is a surface antigen of the human T-lymphocyte lineage that is expressed on all peripheral blood T cells (summarized by Sewell et al., 1986 [PubMed 3490670]). It is one of the earliest T-cell markers, being present on more than 95% of thymocytes; it is also found on some natural killer cells but not on B lymphocytes. Monoclonal antibodies directed against CD2 inhibit the formation of rosettes with sheep erythrocytes, indicating that CD2 is the erythrocyte receptor or is closely associated with it.
