ELISA Kits: Preparing plasma and serum samples


ELISA Kits

RayBiotech manufactures over 1,000 high fully validated, GMP-compliant ELISA kits. In this blog post we explain how to prepare plasma and serum samples for ELISA Kits.

How to Prepare plasma and serum samples for ELISA Kits

For plasma:
  1. Collect whole blood into an EDTA, Citrate or Sodium heparin tube (e.g. BD vacutainer, Cat # 8001302 or 16852).
  2. Centrifuge 10 minutes at 3,000 rpm
  3. Aliquot into small tubes and store at -80°C until use.
For serum:
  1. Collect whole blood into a tube without additives (e.g. BD vacutainer, Cat # 8002527).
  2. Keep at room temperature for 20 minutes.
  3. Centrifuge 10 minutes at 3,000 rpm.
  4. Aliquot into small tubes and store at -80°C until use.

Note: Regardless of the sample type you have, it is strongly recommended that you sub-aliquot all samples after preparation to minimize protein degradation from multiple freeze-thaw cycles. This also ensures availability of sample for further experiments.
