Fig. 4. Chromatographic analysis of Hrp65 oligomers. Recombinant Hrp65-1 purified
on Ni-NTA agarose was fractionated on a Superose HR6TM gel
filtration column and the protein in each fraction was analyzed by 12%
SDS-PAGE and Coomassie staining. Hrp65 was detected from fraction 27 to
fraction 37. A major part of the protein fractionated as a broad peak between
fractions 29-33. The fractionation of molecular mass standards in the gel
filtration column is indicated at the top. The mobilities of molecular mass
standards in the SDS-PAGE are shown on the left, in kDa.
