Immunohistochemistry (PFA perfusion fixed frozen sections) - Anti-Calbindin antibody [5A9] (AB315202)

Immunofluorescent analysis of rat brain cerebellum section stained with ab315202, dilution 1 : 2,000, in red, and costained with rabbit pAb to GFAP, RPCA-GFAP, dilution 1 : 5,000 in green. The blue is Hoechst staining of nuclear DNA. Following transcardial perfusion with 4% paraformaldehyde, brain was post fixed for 24 hours, cut to 45μM, and free-floating sections were stained with the above antibodies. The ab315202 calbindin antibody prominently labels the dendrites and perikarya of Purkinje cells in the molecular layer of the cerebellum. The GFAP antibody stains the processes of Bergmann glia in the molecular layer and astroglia in the granular and white matter layers of cerebellum.

Supplementary information

Calbindin also known as calbindin-D28k is a calcium-binding protein with a molecular mass of approximately 28 kDa. This target is mainly expressed in the neurons of the brain such as in the cerebellum and hippocampus as well as in the kidneys and intestine. Calbindin plays a mechanical role in binding and buffering intracellular calcium ions which is important for the regulation of calcium-dependent signaling pathways. Researchers often use techniques like Calbindin IHC (immunohistochemistry) and ELISA to study its distribution and presence within tissues.
Biological function summary

Calbindin contributes to cellular homeostasis by managing intracellular calcium levels. It does not appear to be part of a larger protein complex but operates independently. This protein helps to protect neurons from calcium overload potentially safeguarding against excitotoxicity which occurs when neurons die from excessive stimulation. Calbindin's function as a calcium buffer is of particular importance in maintaining neuron function and survival in areas with high neuronal activity.

Pathways

Calbindin has a significant role in the calcium signaling pathway and is also involved in the vitamin D pathway. The calcium signaling pathway is vital for many cellular processes like muscle contraction neurotransmitter release and gene expression. The vitamin D pathway regulates calcium and phosphate homeostasis in the body. Calbindin's relationship with proteins such as calmodulin and parvalbumin both involved in calcium regulation highlights its importance in maintaining cellular functions.

Abnormal Calbindin expression has been observed in conditions like epilepsy and Parkinson's disease. In epilepsy its decreased expression can impact the ability of neurons to regulate calcium properly leading to increased vulnerability to seizures. In Parkinson's disease altered Calbindin levels have been associated with the selective vulnerability of dopamine neurons. These diseases highlight the connection between Calbindin and proteins like alpha-synuclein known for its role in Parkinson's pathology emphasizing the need to understand its contribution to disease mechanisms.
