...The recombinant protein TrkB-Ig2, which is an extracellular Ig-like domain of the receptor TrkB that binds to BDNF with picomolar affinity, was produced in-house and diluted in 20 mM Tris buffer, pH 8.2; 100 mM NaCl; and 10% glycerol (Banfield et al., 2001Naylor et al., 2002). BDNF (Neuromics), saline, and TrkB-Ig2 were delivered into the subarachnoid space via osmotic mini-pumps (Alzet). Substances were delivered for 7 d (Model 2001) or 28 d (Model 2004)...
