In vivo conjugation of tHBcAg-SC VLPs with P24-ST. (A) Phenotype of leaves infiltrated with tHBcAg-SC and tHBcAg-SC + P24-ST. Severe necrosis was caused by tHBcAg-SC as shown before. Co-expression of P24-ST substantially mitigated this effect indicating successful conjugation of VLPs and P24. (B) Duplicate Western blots of protein samples from leaves infiltrated with tHBcAg-SC + P24-ST or P24-ST alone (left: anti-P24, right: anti-HBcAg) after double sucrose cushion. Expected size of unconjugated P24 is 24 kDa, expected size after conjugation to tHBcAg is ~ 80 kDa. S = supernatant, 25 = 25% sucrose fraction, 70 = 70% sucrose fraction. C +  = tHBcAg-SC + GFP-ST as positive control. Blots cropped for clarity, for uncropped blots see Supplementary Fig. S5.
