LW2 was used as a reference isolate for the estimation of the molecular masses of B. burgdorferi CRASPs. For calculation, the Wincam gel styler software version 2.2 was employed. FH, serum factor H. ++, strong binding intensity; +, moderate binding intensity; +/−, weak binding intensity; −, no binding.
