Figure 6. Pull-down assay for PrPSc molecules with recombinant full-length MHM2 and MHM2Δ23-88.
(A) Coomassie brilliant blue staining of purified recombinant full-length MHM2 and MHM2Δ23-88. (B) PrPSc(RML) and PrPSc(22L) are pulled down with recombinant full-length MHM2 and MHM2Δ23-88. However, the signal for PrPSc(RML) pulled down with MHM2Δ23-88 is very faint, compared to that for PrPSc(22L). Arrows indicate non-specific signals that might be derived from the anti-His4 ab-Protein G beads used in this assay.
