SPR biosensor for the detection of L. monocytogenes using phage-displayed antibody.
Biosensors & bioelectronics 2007;
23(
2):.
Whole cells of Listeria monocytogenes were detected with a compact, surface plasmon resonance (SPR) sensor using a phage-displayed scFv antibody to the virulence factor actin polymerization protein (ActA) for biorecognition. Phage Lm P4:A8, expressing the scFv antibody fused to the pIII surface protein was immobilized to the sensor surface through physical adsorption. A locally constructed fluidics system was used to deliver solutions to the compact, two-channel SPREETA sensor. Specificity of the sensor was tested using common food-borne bacteria and a control phage, M13K07 lacking the scFv fusion on its coat protein. The detection limit for L. monocytogenes whole cells was estimated to be 2 x 10(6)cfu/ml. The sensor was also used to determine the dissociation constant (Kd) for the interaction of phage-displayed scFv and soluble ActA in solution as 4.5 nM.
