Specific for skeletal and non-muscle actin isoforms (Mr 43,000). Epitope location: NVPAMYVAVLDSGVTHNVPIYHAIMRLDLA.

When using antibody 2G2 in immunolocalization studies the presence of nuclear actin could be demonstrated e.g. in cultured cells after fixation with 4% paraformaldehyde. Immunostaining with cytoplasmic actin was only positive after fixation with methanol (Gonsior et al., 1999).

Reactivity on cultured cell lines: PtK2, SR-NRK, NRK-49F, L6 cells, rat fibroblasts, NIH-3T3, mouse myoblast and myotube cells.
