Product Specific Information
Recombinant rabbit monoclonal antibodies are produced using in vitro expression systems developed by cloning specific antibody DNA sequences from immunoreactive rabbits. Individual clones are screened to select optimal candidates for production.
Advantages include:
- Better specificity and sensitivity
- Lot-to-lot consistency
- Animal origin-free formulations
- Broader immunoreactivity due to larger rabbit immune repertoire
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 isoform is primarily expressed in urogenital tract muscles.
Calponin expression has also been demonstrated in myoepithelial cells from benign and malignant breast lesions. It stains smooth muscle, myoepithelial cells, myofibroblasts, keratinocytes, and nerve fibers.
This antibody helps differentiate breast collagenous spherulosis (positive) from adenoid cystic carcinoma. Adenoid cystic carcinoma in salivary gland tumors is calponin positive.
