By measuring proteins as interacting elements instead of in isolation, the ProteomeLab XL-A/XL-I accelerates the development of diagnostic markers and therapeutic targets and delivers a unique system for protein characterization in solution. The computer-controlled system collects absorbance data from sedimentation equilibrium and sedimentation velocity experiments. The XL-A Windows user interface and data analysis software interprets the data to provide information about association states of interacting molecules, association constants, weight average molecular weight, sedimentation and diffusion coefficients, and conformation changes. These systems can run up to 21 samples using the appropriate cell assemblies and rotor. Basic hands-on instrument and software training is provided with the purchase of an ProteomeLab. Includes an-60 Ti 4-hole rotor, 1 assembled cell (flow through centerpiece, quartz windows), counterbalance set, torque stand and an accessory kit that includes a start-up kit.
