Expression of h2-calponin in myeloid cells. A, Western blots using anti-h2-calponin polyclonal antibody RAH2 and mAb CP22 on total protein extracted from human peripheral mononuclear cells, human myelogenous leukemia cell line K562, human monocyte line THP-1, and in vitro differentiated human myeloid leukemia cell line HL-60 detected significant amounts of h2-calponin. B, no calponin expression was detectable in the human T lymphocyte line Jurkat, mouse T lymphocyte line BW5147, mouse plasmacytoma cell line T1165, and mouse myeloma cell line NS-1 by RAH2 Western blot.
