ProteomeLab™ XL-A/XL-I Protein Characterization System
Native-condition protein characterization. For better lead optimization.

An important component of lead optimization is the ability to evaluate a drug candidate under concentrated "shelf-life" conditions before it moves into expensive preclinical or clinical trials. The ProteomeLab XL-A/XL-I functions over a wide range of concentration, temperature, ionic strength and pH, delivering more thorough characterization than other methods.

Our unique operating methodology measures the relative change in the distribution of molecular weights, providing an efficient way to measure heterogeneity, stoichiometry and self-associating systems.

Because the ProteomeLab XL-A/XL-I's measurements are based on the first principles of thermodynamics and hydrodynamics, no standards or calibrations are required. As a result, you spend less time on setup, and more time on discovery.


Product Features

Multiple Detection Systems

The ProteomeLab XL-A is configured with a scanning UV/Vis detection system that provides sensitivity for low-concentration work and selectivity for optimizing detection based on the sample's maximum absorbance. The addition of Rayleigh Interference Optics provides the capability to measure the change in refractive index resulting from changes in sample concentration. This delivers increased accuracy and the ability to examine a greater concentration range with a wider selection of samples. The XL-I can collect data from both detection systems sequentially, to provide the broadest spectrum of data for protein characterization in solution.

 

Easy Sample Preparation

For easy sample preparation, inject as little as 15µL to 120µL of sample and reference solutions into opposing positions in the cell assembly, and place the assembly into the system. Up to 28 different sample/reference pairs can be studied in a single run, with each having a different set of solute/solvent conditions (pH, ionic strength, concentration). This provides data for accurate analysis in as little as three hours. Your sample can be retrieved for additional analysis.

 

Flow-Through Centerpiece Assembly

A pre-assembled cell features a flow-through centerpiece that saves you time. Sample and reference solutions can be directly injected in the cell and retrieved for additional analysis without assembling or disassembling the cell. A second hole above each channel allows the cell to be cleaned and rinsed (with tubing and syringe) and ready for the next run.
