Figure 1From: Dissection of an old protein reveals a novel application: domain D of Staphylococcus aureus Protein A (sSpAD) as a secretion - tagComparison of the protein solubility with and without sSpAD tag. The solubility of NproEDDIE-pep6His, SOD and GFPmut3.1 with and without sSpAD tag, expressed under the control of a LacUV5 promoter, was determined under defined cultivation conditions.Back to article page
