TaqMan® Protein Assays combine the sensitive, specific protein-binding capabilities of antibodies with the superior relative quantitation capabilities of 5′ nuclease real-time PCR. They enable fast, easy identification and relative quantification of proteins from small sample sizes or limited numbers of cells-all in a homogeneous assay format. Through our Custom Biology Services, we now offer both do-it-yourself and outsourced service options for accessing TaqMan Protein Assays.

Custom Services: Extend your research team


Our Custom Biology Services allow you to obtain quality, validated assays that meet your defined requirements; while saving your lab team resources. Our flexible process allows you to choose only the project milestones that you need.

To discuss your custom TaqMan Protein Assay requirements with our team, send us an online inquiry, and a dedicated project manager will be assigned to your project and will follow up to discuss requirements.

Benefits of TaqMan Protein Assays

  • Enables direct correlation of mRNA and/or miRNA expression to protein expression on the same real-time PCR platform
  • Provides greater sensitivity and a more quantitative readout than western blots and immunostaining—no fixing or staining cells
  • TaqMan Protein Assays Open Kit enables simple assay development from biotinylated antibodies for your proteins of interest—even using a single polyclonal antibody

Applications for TaqMan Protein Assays

Dedicated project management


From your initial inquiry through every milestone of your project, you can expect exceptional service and frequent, proactive communication from a dedicated project manager. Your project manager will help ensure all parties involved in the project are aligned on project requirements, timelines and budgets.
