Purchasing Guide: Assays, Kits, and Reagents | Lab Manager

Assays, kits, and reagents are an important fixture in life science, environmental, and research labs. Assay kits conveniently provide most or all of the materials needed to conduct specific tests, which may require complex or hard-to-develop components like enzymes and antibodies. It is very important to purchase assays, kits, and reagents from trusted sources, as poor quality components can alter experimental outcomes and reduce reliability.

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

  1. Do the reagents need to be pure for the intended application?

  2. Are there additional compliance requirements such as use of the same lot for the duration of an extended experiment?
  3. How consistent and reliable are the results from different lots?
  4. Is the assay, kit, or reagent compatible with existing lab equipment?
  5. Does the assay, kit, or reagent reduce lab work time to implement?
  6. Are there potential contaminants from the packaging that might affect the outcome of the intended experiments? Do these contaminants pose an environmental threat that require specialty disposal? 
  7. What is the unit price per test?

Purchasing Tip

Though it may be tempting to purchase inexpensive reagents to reduce running costs, it is important to consider the reputation of manufacturers and their quality control measures. Does the manufacturer report transparency and reliable quality control? To ensure integrity of experiments and reliability of results, purchase reagents from trusted manufacturers who go the extra mile in ensuring high-quality products.

Considerations for Acquiring Custom Kits

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.

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.
