Product Specific Information

Immunohistochemistry (PFA fixed): incubate antibody for 30 minutes at room temperature (RT).
Staining of formalin-fixed tissues requires heating tissue sections in 10 mM Tris with 1 mM EDTA, pH 9.0, for 45 minutes at 95°C, followed by cooling at RT for 20 minutes.

Target Information

Calponin is a thin filament-associated protein involved in the regulation and modulation of smooth muscle contraction. It binds to actin, calmodulin, troponin C, and tropomyosin.
Calponin is expressed in smooth muscle and tissues containing significant amounts of smooth muscle. Two isoforms exist: 34 kDa and 29 kDa. The 29 kDa form is primarily found in urogenital tract muscle.
Calponin expression has also been observed in myoepithelial cells from benign and malignant breast lesions. It stains smooth muscle, myoepithelial cells, myofibroblasts, keratinocytes, and nerve fibers.
It identifies myoepithelial cells in breast lesions and helps differentiate breast collagenous spherulosis (positive) from adenoid cystic carcinoma. Adenoid cystic carcinoma in salivary gland tumors is calponin positive.
