Anti s100β cell monoclonal antibody

For immunofluorescence, the sections were washed 3 times with PBS, and then exposed to 0.1% bovine serum albumin solution containing 0.1% Tween 20 in PBS for 4 hr at room temperature. Next, sections were incubated overnight with a solution containing primary antibodies as follows: antiglial fibrillary acidic protein monoclonal antibody (1:400, Santa Cruz Biotechnology, Santa Cruz, CA, USA) for astrocyte, anti-neurofilament rabbit polyclonal antibody (1:400, Sigma Chemical Co., St. Louis, MO, USA) for axons, anti-S100β cell monoclonal antibody (1:400, Cosmo Bio Co., Tokyo, Japan) for Schwann cells, and anti-BDNF rabbit polyclonal antibody (1:400, Santa Cruz Biotechnology) for BDNF. After washing, the sections were incubated 2 hr with secondary antibodies as follows: fluorescein isothiocyanate anti-mouse secondary antibody (1:400, Jackson ImmunoResearch Laboratories, West Grove, PA, USA) for neurofilament and Schwann cells or CY3 anti-rabbit secondary antibody (1:800, Jackson ImmunoResearch Laboratories) for astrocyte and BDNF. The sections were mounted and examined by a fluorescence microscope (Nikon Eclipse 50i, Nikon Inc., Melville, NY, USA).
