Embodiment 1
[0074] Example 1. Refolding of recombinant human bone morphogenetic protein-2rhBMP-2 inclusion bodies by affinity chromatography
[0075] 1. Denaturation of rhBMP-2 inclusion bodies
[0076] Inclusion body solution: 0.1mol / L Tris-HCl, 8mol / L urea, 0.1mol / L DTT, 5mmol / L EDTA; pH8.5. Each concentration is the final concentration of the corresponding component in the solution, and the solvent is water.
[0077] Denaturation: Dissolve inclusion bodies at a ratio of 1 gram of recombinant human bone morphogenetic protein-2rhBMP-2 inclusion body: 10 mL of inclusion body solution, shake at 25°C and 100 r / min for 6 hours, centrifuge at 12,000 g for 30 minutes at high speed, and collect the supernatant The solution is denatured rhBMP-2 protein solution.
[0078] 2. Refolding of rhBMP-2 by affinity chromatography after denaturation
[0079] 1. Pre-purification
[0080] In order to improve the purity of the protein and reduce the content of impurities such as nucleic acid, the denatur...
