Aim:
To establish a steady purification method for producing recombinant humanized anti-HBsAg Fab from yeast fermentation supernatant.
Methods:
Humanized anti-HBs scFv was used to immunize BALB/c mice to obtain anti-scFv monoclonal antibody (mAb) which was used to purify recombinant humanized anti-HBsAg Fab from yeast fermentation supernatant by affinity chromatography.
Results:
The purity of purified recombinant anti-HBsAg Fab was above 95% and its recovery rate was about 75%-85%.
Conclusion:
An efficient affinity chromatography suitable for purification of recombinant humanized anti-HBsAg Fab in large-scale was established.
