Calponin 1 ELISA Kits

Calponin is a smooth muscle specific, actin-, tropomyosin- and calmodulin-binding protein thought to be involved in regulation of actomyosin as well as the regulation or modulation of contraction (1). Calponin binds filamentous actin (F-actin) through two distinct sites ABS1 and ABS2, with an affinity in the low micromolar range (2) Immunoreactivity for calponin, along with alpha-smooth muscle actin and smooth muscle myosin heavy chains, confirms the known neoplastic myoepithelial component of ...
