Can the Ni-NTA and Strep-Tactin Superflow Cartridges be reused?
FAQ ID -1607

If the same protein is purified, the Ni-NTA and Strep-Tactin Superflow Cartridges can be used more than once. Cleaning in place (CIP) is recommended between purifications (0.5 M NaOH, 0.5 ml/min, 7.5 cv for 15 min).

However, for sequential purification of different proteins we recommend to use different cartridges. Please note that cartridges cannot be opened!
