 Purchasing Guide: Assays, Kits, and Reagents

It is very important to purchase assays, kits, and reagents from trusted sources, as the experiments conducted will only be as good as the components in these products

Lab Manager

Assays, kits, and reagents are used in many different life science, environmental, and research labs. Assay kits have become very important in providing the materials needed to conduct specific tests that require complex or hard-to-develop components like enzymes, antibodies, genomics, and cells. It is very important to purchase assays, kits, and reagents from trusted sources, as the experiments conducted will only be as good as the components in these products. For a full list of laboratory assay, kit, and reagent manufacturers, see our online directory: LabManager.com/assays-kits-reagents-manufacturers

7 Questions to Ask When Buying Assays, Kits, and Reagents:

  1. How pure do the components need to be for this application?
  2. Is the same lot needed for an extended experiment?
  3. How similar or dissimilar are the results from different lots?
  4. Does the assay, kit, or reagent work well with the existing lab equipment?
  5. Does the assay, kit, or reagent reduce lab work time to implement?
  6. How important are potential contaminants from the packaging?
  7. What is the unit price per test?

Purchasing Tip

An important aspect of running a lab is the need for a dependable supply of reagents. Have a plan in place to ensure long-term reagent supply and storage so you don’t run out and lose productivity. Depending on the nature and throughput of your work, having multiple sources may be necessary.

Test Kits Early

Testing different ELISA kits to find the one that best suits your work is most beneficial early in the drug development process. Make sure to test out a wide range of kits before advancing too far into the development process and then stick with it, as only one kit from a manufacturer can be used when obtaining regulatory approval.
