细胞上清液提取常见问题解析

培养 24 - 48 h，细胞汇合度达到 80% - 95% 左右时收取上清，该上清液即可用于提取外泌体。 使用外泌体专用无血清培养基： 待细胞汇合度~50%时，移去原有完全培养基，添加新培养基进行培养，新培养基由 50% 外泌体专用无血清培养基 + 50% 完全培养基组成； 待细胞生长汇合度约为70-80%时，移去培养基； 使用1×PBS溶液将细胞润洗2-3次； 加入外泌体专用无血清培养基继续培养24 - 48 h，待细胞汇合度到 80% - 95% 时收取细胞培养上清液，该上清液即可用于外泌

tube containing 200 microliters of 100mg/ml CNBr in 70% formic acid. CNBr stocks are 200 milligrams/ml in 70% formic acid and are stored at -70°C. 70% formic acid is made from 98-100% formic acid and MQH2O. Optional: If you want to know

Assisted large fragment insertion by Red/ET-recombination (ALFIRE)―an alternative and enhanced method for large fragment recombineering

from Genebridges. Electroporation was performed at 1.35 kV, 25 μF, 200 Ω using an Eppendorf electroporator (2510). Bacteria were incubated in 1 ml LB media at 37°C, 1100 rpm for 1�2 h before plating on agar plates conditioned with the appropriate antibiotic(s
