Complement System Solutions

Svar has decades of experience in designing products for studying the complement system. Our complement experts have created assays that let you study any part of the complement system – from individual complement components and the amplification loop to all three complement system pathways. Just follow the complement path.

Complement Solutions

We offer complement assays in convenient ELISA and iLite® cell-based reporter gene formats. Regardless of what format you select, you will get:

  • Reliable, objective, and easy-to-interpret results
  • Results in just a few hours
  • Low inter-assay variability and excellent reproducibility
  • Ready-to-use reagents for a streamlined workflow
  • Excellent specificity
  • Lower batch-to-batch variation & faster results than hemolytic methods
