• What sample types can be assayed?
  Peptide levels in any biological sample can be measured. Any biological sample can be accurately assayed, including plasma, serum, tissue, and CSF.
  
  
• How will our samples be prepared?
  Our experienced team can help determine the optimal sample preparation procedure. For example, we often recommend performing peptide extraction for most sample types. This helps remove large proteins normally found in biological fluids that can casue high background noise (e.g. hemoglobin, albumins, clotting factors). Additionally, extracted samples can be concentrated, which is essential for peptides and hormones with low normal circulating levels.
  
  
• How much will it cost?
  Pricing starts at $20 per sample when assaying samples in bulk. We also offer sample extraction-only services. Please contact us to receive a price quote.
  
  

Below is an example of the data and analysis you can expect when using our services. Human plasma samples were assayed before and after feeding in order to establish a correlation between Irisin and energy metabolism.
