Add 75 μl of 0.1 mg ml−1 poly-L-ornithine onto each coverslip. Incubate the plates at 37 °C overnight. The next day, aspirate the poly-L-ornithine and let the coverslips dry at roomtemperature for ~30 min. Wash three times using 1 ml of sterile water for each well. Leave the plate open in the hood until completely dry. Cover the plates, wrap in foil, label with date and store at −20 °C for up to 4 weeks. 9 M% v0 r8 L: h# E N1 B, B0 o, }2 }Laminin-coated six-well plate—Dilute laminin with fresh neural differentiation medium to a final concentration of 20 μg ml−1. Add 300 μl of laminin solution to each well of a sixwell plate. Allow the medium to hold as a big drop and spread within the central area of the well. Do not let the medium drain to the edge. Incubate the plate at 37 μC for 1 h. Laminin easily absorbs to plastic and tends to form aggregates at room temperature. Store laminin at −80 °C and thaw at 4 °C before using. Avoid aliquotting laminin into plastic tubes from the original glass vial. : H& B9 ]6 _1 ?( i' s( F/ i/ T作者: 千细胞 时间: 2011-2-25 15:36
