Lt. Goh et al., Production and purification of recombinant Blomia tropicalis group 5 allergen from Pichia pastoris culture, BIOTECH LET, 23(9), 2001, pp. 661-665
The gene of Blomia tropicalis group 5 allergen (Blo t 5) was cloned and exp
ressed in Pichia pastoris KM71. Selected KM71 clones were cultivated in a f
ed-batch bioreactor feeding first glycerol then followed by methanol. Recom
binant Blo t 5 constituted about 30% of the total broth protein after 60 h
cultivation. The harvested broth was purified to > 95% purity by a two-step
anion exchange chromatography. The overall yield was 37 mg Blo t 5 per lit
re broth.
