      • Anti-Calretinin
      Background InformationCalretinin is a 29 kDa calcium binding protein that is expressed in central and peripheral nervous system and in many normal and pathological tissues. Calretinin is also considered an important diagnostic aid in the differential diagnosis of cystic and solid ameloblastic tumors. The rat and human calretinin exhibit 98% sequence homology and 91% homology to many other species. Calretinin is generally expressed with two other calcium binding proteins Calbindin D-29 and parvalbumin in CNS and other peripheral tissues. Calretinin antibodies have been used to detect a number of carcinomas by clinicopathological, immunohistochemical techniques including, epithelial malignant mesotheliomas, Ovarian yolk sac tumor, Adenomatoid tumors of the uterus etc.

      Entrez Gene Number
      Entrez Gene SummaryCalbindin 2 (calretinin), closely related to calbindin 1, is an intracellular calcium-binding protein belonging to the troponin C superfamily. Calbindin 1 is known to be involved in the vitamin-D-dependent calcium absorption through intestinal and renal epithelia, while the function of neuronal calbindin 1 and calbindin 2 is poorly understood. The sequence of the calbindin 2 cDNA reveals an open reading frame of 271 codons coding for a protein of 31,520 Da, and shares 58% identical residues with human calbindin 1. Calbindin 2 contains five presumably active and one presumably inactive calcium-binding domains. Comparison with the partial sequences available for chick and guinea pig calbindin 2 reveals that the protein is highly conserved in evolution. The calbindin 2 message was detected in the brain, while absent from heart muscle, kidney, liver, lung, spleen, stomach and thyroid gland. There are two additional forms of alternatively spliced calbindin 2 mRNAs encoding C-terminally truncated proteins. Exon 7 can splice to exon 9, resulting in a frame shift and a translational stop at the second codon of exon 9, and encoding calretinin-20k. Exon 7 can also splice to exon 10, resulting in a frame shift and a translational stop at codon 15 of exon 10, and encoding calretinin-22k. The truncated proteins are able to bind calcium.

      Quality AssuranceImmunohistochemistry(paraffin) Analysis:
      Calretinin (cat. # AB5054) staining on Human Cerebellum. Tissue pretreated with Citrate, pH 6.0 plus. Antibody was diluted to 1:200 (5.0 µg/mL), using IHC-Select® Detection with HRP-DAB. Immunoreactivity is seen as a nuclear and cytoplasmic punctate staining on neurons (brown).
      Optimal Staining With Citrate Buffer Epitope Retrieval: Human Cerebellum.

      Storage and Shipping Information
      Storage ConditionsStable for 1 year at -20°C in undiluted aliquots from date of receipt.

      Handling Recommendations:
      Upon first thaw, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.
