Protocol
Available protocols: Immunofluorescence (Frozen)
Specificity / Sensitivity
CNPase (D83E10) Feline Chimeric Monoclonal Antibody recognizes endogenous levels of CNPase protein.
Species Reactivity: Human, Mouse, Rat
Source / Purification
This recombinant chimeric antibody is engineered from CNPase (D83E10) XP  Rabbit mAb #5664 according to animal-free protocols. The chimeric antibody retains its antigen-binding Fab regions from the original rabbit monoclonal antibody but contains a feline-derived Fc domain. When multiplexing, Fc-directed rabbit secondaries are required to detect rabbit-host primary antibodies. The parent antibody, CNPase (D83E10) XP  Rabbit mAb #5664, is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val81 of human CNPase protein.
Background
CNPase (2', 3'-cyclic nucleotide 3'-phosphodiesterase) catalyzes the hydrolysis of 2', 3'-cyclic nucleotides to produce 2'-nucleotides. The molecular function and native substrate of this nucleotide phosphodiesterase remains under investigation (1). High CNPase expression is seen in oligodendrocytes and Schwann cells as CNPase accounts for roughly 4% of the total myelin protein in the central nervous system (2). CNPase binds to tubulin heterodimers and plays a role in tubulin polymerization, and oligodendrocyte process outgrowth (3). Typical myelination is seen in CNPase knock-out mice, but they suffer severe neurodegeneration from axonal loss and oligodendrocytes display abnormal paranodal loop structure prior to axonal degeneration. Paranodal loops typically contact the axolemma in axon-glial signaling; neurodegeneration in CNPase knock-out mice is a secondary consequence of impaired cell-cell communication (4).
