Figure 2From: Efficient production and secretion of bovine β-lactoglobulin by Lactobacillus caseiDose-dependent nisin induction of staphylococcal nuclease production and secretion. L. casei BL23 strain was co-transformed with pSEC:Nuc and pNZ9520 plasmids. Protein extracts were analyzed by immunoblotting using rabbit polyclonal anti-Nuc antibodies as described in the Materials and Methods section. Arrows indicate positions of Nuc and its precursor form (pre-Nuc).Back to article page
