Anti-Calponin 1 / CNN1, clone MSVA-455R

Antibody in 1X PBS with 0.05% BSA, 0.05% sodium azide. Calponin 1 (CNN1) is a smooth muscle-specific actin-binding protein that serves as a reliable marker of differentiated smooth muscle cells in tissue sections. The CNN1 Antibody for IHC / Smooth Muscle Tissue Architecture Marker is optimized for detection of this protein in immunohistochemistry, where it highlights smooth muscle organization and structural relationships within complex tissue environments. Its consistent expression in contractile cell populations makes it particularly useful for evaluating tissue architecture and identifying smooth muscle compartments.CNN1 antibody, also referred to as Calponin 1 antibody or Calponin antibody in the literature, enables visualization of smooth muscle cell populations in formalin-fixed, paraffin-embedded tissues. Expression is highly restricted to smooth muscle cells, including vascular smooth muscle and muscular layers of organs such as the gastrointestinal tract, uterus, and bladder. This restricted expression pattern provides strong contrast against surrounding tissues and supports clear identification of smooth muscle structures in histological analysis.Functionally, Calponin 1 regulates actin filament interactions and contributes to contractile activity, but in immunohistochemistry applications its primary value lies in delineating tissue architecture. In tissue microarray studies, CNN1 staining allows comparison of smooth muscle organization across multiple tissue types and disease states, providing insight into structural changes, differentiation status, and tissue composition. This makes CNN1 Antibody for IHC particularly valuable in large-scale histological evaluations and comparative tissue studies.In immunohistochemistry, CNN1 produces strong cytoplasmic staining in smooth muscle cells, often outlining muscle bundles, vascular walls, and muscular layers. This staining pattern provides clear visualization of tissue organization and enables identification of anatomical structures that rely on smooth muscle function. The consistent localization of CNN1 supports interpretation of both normal tissue architecture and pathological alterations.Subcellularly, Calponin 1 associates with actin filaments in the cytoplasm, which corresponds to the observed staining distribution in IHC. This localization contributes to the characteristic appearance of smooth muscle structures and reinforces its utility as a structural marker. These features make CNN1 Antibody for IHC a reliable tool for morphological analysis and tissue-based studies.This CNN1 antibody is supported by immunohistochemistry data demonstrating strong and consistent staining across a wide range of tissues, including tissue microarray formats. These features support its use in studies of tissue architecture, smooth muscle identification, and histological analysis.Additional Calponin 1 antibody reagents targeting CNN1 are available for related research applications.This antibody is also part of a broader collection of IHC antibodies validated by tissue microarray analysis, supporting consistent staining across normal and cancer tissues.
