Rat CALD (Caldesmon) ELISA Kit (RTES01069)

This colorimetric immunoassay from Assay Genie quantifies Caldesmon (CALD), an actin- and myosin-binding protein that regulates smooth muscle contraction and cytoskeletal remodeling in vascular and visceral tissues. The kit enables protein-level measurement in rat-derived samples and supports research applications in vascular biology, gastrointestinal motility studies, uterine contractility investigations, and tumor cell migration models. Caldesmon exists in two isoforms — the high-molecular-weight variant abundant in differentiated smooth muscle and the low-molecular-weight variant expressed across non-muscle cell types — giving researchers a quantitative handle on smooth muscle differentiation markers, cytoskeletal regulation events, and contractile phenotype switching in rat experimental systems. Each microplate-format kit ships with all reagents required for standard curve generation and sample measurement, and components should be handled according to the enclosed protocol, with unused reagents stored refrigerated to preserve activity across the working shelf life of the product.
