Figure 1From: Staphylococcus aureus immunodominant surface antigen B is a cell-surface associated nucleic acid binding proteinSDS PAGE analysis of recombinant IsaB. IsaB-CBD fusion peptide was produced in E. coli, purified over a chitin column, and purified, untagged IsaB was cleaved off the column. Lane 1, molecular weight standards; Lane 2, whole cell lysate; Lane 3, CBD tag stripped from chitin beads by boiling in SDS PAGE loading buffer; Lane 4, purified IsaB after CBD cleavage and column elution.Back to article page
