FIG 4.

UL11 is an elongated monomer. (A) MALDI-TOF spectrum of UL11-StII. The x axis shows the mass-to-charge ratio (m/z) in daltons and the y axis shows relative abundance (%) scaled for the mass range in x. (B) Size exclusion chromatography (SEC) A₂₈₀ traces and gels. The elution volumes of calibration standards used to calculate apparent molecular masses (kDa) are depicted in gray and with gray arrows. (C) Coomassie blue-strained gel of UL11 incubated with increasing amounts of BS³ cross-linker.
