Background of Calretinin

Calbindin is a calcium-binding protein belonging to the troponin C superfamily. Calretinin is expressed in central and peripheral nervous system and in many normal and pathological tissues. The rat and human calretinin exhibit 98% sequence homology and 91% homology to many other species. Two calcium binding proteins, calbindin and calretinin, have been reported to be expressed in abundance in Purkinje cells and other cell types in the cerebellum.

Antibody Validation

Boster validates all antibodies on WB, IHC, ICC, Immunofluorescence and ELISA with known positive and negative samples to ensure specificity and high affinity.

6 Customer Q&As for Anti-Calretinin/CALB2 Antibody


Would PA1015 anti-Calretinin/CALB2 antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?

Verified Customer

Verified customer

Asked: 2020-04-22


It shows on the product datasheet, PA1015 anti-Calretinin/CALB2 antibody as been validated on WB. It is best to use PFA for fixation because it has better tissue penetration ability. PFA needs to be prepared fresh before use. Long term stored PFA turns into formalin, as the PFA molecules congregate and become formalin.

We are interested in to test anti-Calretinin/CALB2 antibody PA1015 on mouse adipose tissue cerebellum for research purposes, then I may be interested in using anti-Calretinin/CALB2 antibody PA1015 for diagnostic purposes as well. Is the antibody suitable for diagnostic purposes?

T. Yang

Verified customer

Asked: 2019-04-18


The products we sell, including anti-Calretinin/CALB2 antibody PA1015, are only intended for research use. They would not be suitable for use in diagnostic work. If you have the means to develop a product into diagnostic use, and are interested in collaborating with us and develop our product into an IVD product, please contact us for more discussions.

Does anti-Calretinin/CALB2 antibody PA1015 work on zebrafish IHC with adipose tissue cerebellum?

T. Patel

Verified customer

Asked: 2018-06-05


Our lab technicians have not tested anti-Calretinin/CALB2 antibody PA1015 on zebrafish. You can run a BLAST between zebrafish and the immunogen sequence of anti-Calretinin/CALB2 antibody PA1015 to see if they may cross-react. If the sequence homology is close, then you can perform a pilot test. Keep in mind that since we have not validated zebrafish samples, this use of the antibody is not covered by our guarantee. However we have an innovator award program that if you test this antibody and show it works in zebrafish adipose tissue cerebellum in IHC, you can get your next antibody for free.
