FAQ
How do I choose the right complement assay?
The choice depends on whether you want to study complement activation, complement function, individual complement biomarkers, or cell-based complement responses.
What complement pathways can be studied using Svar's assays?
Svar offers assays for the classical, alternative, and lectin complement pathways as well as assays targeting individual complement components and activation products.
What is the difference between complement activation and complement function assays?
Complement functional assays measure how effectively a complement pathway is working, while complement activation assays measure biomarkers generated when the complement system has been activated.
Do you offer both ELISA and cell-based complement assays?
Yes. The portfolio includes both ELISA assays and iLite cell-based reporter assays for complement research.
Which complement biomarkers can be measured?
Assays are available for biomarkers such as, C3a, C5a, C4d, TCC, Factor P (Properdin) and other complement-related assays.
Can these assays be used in drug development?
Yes. The assays support complement research across basic research, translational studies and drug development.
How can I identify the best assay for my research project?
Researchers can browse products by application area or contact Svar's complement specialists for guidance
Do you offer RUO and IVD complement assays?
Yes. Several of our complement assays are available in both RUO and IVD formats, depending on the intended application and local regulatory requirements.
