N. Ramirez et al., Single-chain antibody fragments specific to the hepatitis B surface antigen, produced in recombinant tobacco cell cultures, BIOTECH LET, 22(15), 2000, pp. 1233-1236
An anti-hepatitis B surface antigen (HBsAg), single-chain Fv antibody fragm
ent (scFv) with a 6-histidine N-terminal tag was produced in cultured trans
genic tobacco cells. Western blot and antigen-specific chromatography showe
d high levels of biologically active scFv in the culture supernatant (1 mg
l(-1)) and in cells (5 mg kg(-1)). A simple one-step scFv purification was
developed using immobilized metal ion affinity chromatography.
