Silver stain SDS-PAGE demonstrating the ability of nine different types of dye-functionalized hydrogel microparticles (listed above each gel) to concentrate B. burgdorferi proteins in water. Acid Black 48 dye was determined to be the most effective at concentrating the total protein mix. OspA 31 kDa, OspB 34 kDa, IS = initial solution, S = supernatant, and P = microparticle content.
