Protocol Available protocols: Immunofluorescence (Frozen) Specificity / Sensitivity Calbindin (D1I4Q) Horse Chimeric Monoclonal Antibody recognizes endogenous levels of total calbindin protein. Species Reactivity: Human, Mouse, Rat Source / Purification This recombinant chimeric antibody is engineered from Calbindin (D1I4Q) XP Rabbit mAb #13176 according to animal-free protocols. The chimeric antibody retains its antigen-binding Fab regions from the original rabbit monoclonal antibody, but contains a horse-derived Fc domain. When multiplexing, Fc-directed rabbit secondaries are required to detect rabbit-host primary antibodies. The parent antibody, Calbindin (D1I4Q) XP Rabbit mAb #13176, is produced by immunizing animals with recombinant protein specific to the amino terminus of mouse calbindin protein. Background Calcium-binding proteins of different subfamilies regulate the second messenger calcium. Calbindin, calmodulin, S-100, parvalbumin, and troponin C are members of the low molecular weight calcium-binding protein family (1). Calbindin is expressed in discrete neuronal populations within the CNS and is thought to act as an intracellular calcium buffering protein. Most Purkinje cells express calbindin, which is expressed when neurons start to migrate and differentiate. In contrast, other calcium buffering proteins, such as parvalbumin, are expressed later during development and in parallel with increasing neuronal activity (2).
