Figure 1(a): Gel overlay assay using crude laparaxin as described in Materials & Methods section. 15 µl of crude laparaxin was subjected to SDS PAGE (8- 16% Tris-HCl ready gels from BioRad). The gel piece with molecular weight marker was stained with BioRad Coomassie brilliant blue R-250 and de-stained overnight. The marker gel piece was then aligned in parallel with a fresh gel piece that was rinsed with water for 15 min after electrophoresis and overlaid with Lactococcus lactis LM 2030.
