Calretinin Antibody (CALB2/7029R) - Azide and BSA Free Summary

• Description: 1.0 mg/ml of antibody purified from rabbit anti-serum by Protein A. Prepared in 10mM PBS WITHOUT BSA. Also available at 200 ug/ml WITH BSA & azide (NBP3-13799).
  
  Antibody with azide - store at 2 to 8C. Antibody without azide - store at -20 to -80 C.
• Additional Information: Recombinant Monoclonal Antibody
• Immunogen: Recombinant human Calretinin protein fragment (around aa23-242) (exact sequence is proprietary) (Uniprot: P22676 )
• Localization: Cytoplasm, Nucleus
• Marker: Mesothelioma Marker
• Specificity: It recognizes a protein of about 29kDa, which is identified as Calretinin (also known as Calbindin 2). Calretinin is a vitamin D-dependent calcium-binding protein involved in calcium signaling. It is present in subsets of neurons throughout the brain and spinal chord, including sensory ganglia. Antibody to calretinin is useful in differentiating mesothelioma from adenocarcinomas of the lung. It also aids in differentiating adrenal cortical neoplasms from pheochromocytomas.
• Isotype: IgG
• Clonality: Monoclonal
• Host: Rabbit

Applications/Dilutions

• Dilutions:
  • Immunohistochemistry-Paraffin 1-2 ug/ml
  • Protein Array
  • Western Blot 1-2 ug/ml
• Application Notes: Immunohistochemistry (Formalin-fixed): 1-2ug/ml for 30 minutes at RT. Staining of formalin-fixed tissues requires heating tissue sections in 10mM Tris with 1mM EDTA, pH 9.0, for 45 min at 95C followed by cooling at RT for 20 minutes
• Theoretical MW: 29 kDa.
  Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Background

Calretinin (CAB29, calbindin 2) is a calcium binding protein that belongs to calbindin family. It is mainly found in neuronal tissue, high expressed in auditory neurons. It has been implicated in as a calcium buffer, calcium sensor, and as a regulator of apoptosis (1). Calretinin is considered as a specific marker of mesothelllal cells; it is the only marker that has the utility in distinguishing between sarcomatoid mesotheliomas and sarcomatoid renal cell carcinomas (2). It is widely used in the panel of makers for distinguishing mesothlioma from adenocarcinoma. Along with calretinin, the panel includes E-cadherin, CEA, and cytokeratin 5/6 (3).
