Anti-Calretinin Antibody

Calretinin 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.

Reactivity with other species has not been determined

Specific for calretinin. Recognizes both the calcium-bound and calcium-unbound conformations of calretinin by western blots.

This Anti-Calretinin Antibody is validated for use in IH, IH(P), WB for the detection of Calretinin.

Western blot:
1:1,000-1:2,000 of a previous lot was used.

Immunohistochemistry:
1:1,000-1:10,000
Antibody works in paraffin embedded tissues.

Optimal working dilutions must be determined by the end user.

Immunohistochemistry(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.

Replaces: AB149

Unpurified

Rabbit polyclonal serum contains no preservative.

Stable 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.

Control
