How will C-Plex service advance your protein analysis?

Problem

Do you want to validate your research findings but cannot find an assay that measures just the proteins you need? Are you not satisfied with the quality of existing ready-made assays? Do you work with difficult proteins that no assay exists?

Solution

C-plex delivers an assay that fits your unique requirements for protein analysis and adheres to stringent international quality criteria.

What is C-Plex assay development

C-Plex is a fully customizable assay development service that leverages the power of Luminex(™) technology to develop a protein assay that can measure the proteins that matter to you in the samples of interest.

The C-Plex service follows a rigorous development process compliant with the criteria set by the ISO13485 and the regulations for the development of in-vitro diagnostic assays. The development process involves the use of high-quality raw materials, standard operating procedures and verification of analytical performance characteristics.

Select the type of assay (immunoassay, serology etc), protein targets and sample type and we take care of the rest. In a few weeks we prepare a reagent kit that you can choose to use directly in your lab or with our mid-plex protein analysis service.

The C-plex Solutions

C-Plex STANDARD

Best choice if:

  • Your proteins of interest are “well know” proteins with significant number of publications and many antibodies available from trusted vendors
  • You have an already validated antibody pair from a trusted supplier
  • You require a cost effective solution

C-Plex ADVANCED

Best choice if:

  • You have a difficult protein target
  • You want to maximize the chances of identifying the best performing assay for your samples
  • You have generated your own antibodies
