SE-HPLC of Pichia and baculovirus Pfs25. a Pfs25 from Pichia (black line) and baculovirus (dashed red line) eluted predominantly as a monomer. Arrows indicate shoulder observed for Pichia Pfs25 that most likely represents a higher molecular weight component co-eluting with monomer. The shoulder present for Pichia Pfs25 could not be fully resolved and integrated. Molecular weight gel filtration standards (Bio-Rad, Hercules, CA) indicated a monomer, with Pfs25 eluting at its expected molecular weight (between 44 and 17 kDa). b Normalized absorbance for eluted monomer peaks
