Abstract:
Objective To prepare polyclonal antibodies of anti Nogo-66, the extracellular region of one central nervous system neurite regeneration inhibitor Nogo, which could be used to further identification and functional study of Nogo molecule.Methods Preparing rabbit anti rat Nogo-66 polyclonal antibodies with a purified Nogo-66 fusion protein expressed in E.coli system. Studying its specificity by Western-blot and immuno-histochemical techniques and identifying its biological activity in PC12 cells.Results The high titer (1∶[KG-*2]10 000) anti rat Nogo-66 polyclonal antibodies were obtained.This antibody could specifically recognize the Nogo protein expressed in E.coli system.Immuno-histochemical staining indicated that the Nogo was widely expressed in rat spinal cord neurons and oligodendrocytes.It could effectively block the neurite extensioninhibition of Nogo protein in PC12.Conclusion Successful preparation of anti rat Nogo polyclonal antibodies provides a useful tool in identification or further functional study of Nogo molecule.
