查询词典 purification

METHODS: According to adherent + Thy1.1 antibody and complement-purification method, cranium was opened to expose olfactory bulb. Thereafter, two olfactory bulbs were obtained to remove cerebral pia mater, blood capillary, and peripheral tissues; additionally, olfactory nerve layer and olfactory bulb granular layer were sheared into 1-mm3 pieces for extract single-cell suspension. The cells were adjusted at the density of 1×107 /L and incubated with poly-l-lysine-coated culture bottle or culture plate in 5% CO2 incubator at 37 ℃. On the third day, cells were cultured with serum-free DMEM/F12 culture media.
