Get lists of questions to ask when buying either qPCR or RNAi reagents; the most recent chemicals, reagents, and standards releases; and an updated chemicals, reagents, and standards manufacturer's list in this section.

Top 5 Questions You Should Ask When Buying qPCR Reagents

1. What key performance attributes does the company’s reverse transcription and qPCR reagents offer that the competition does not offer? Do these attributes make your choice the most fit for your application?

2. Are you able to submit data files and questions to your reagent provider to help ensure your lab’s success? Does your reagent provider offer on-site and electronic qPCR application support, and technical phone support before and after product purchase?

3. qPCR reagents have been on the market for many years. What improvements in enzyme engineering and buffering chemistry has the company taken to provide the latest in qPCR reagents performance?

4. Does your reagent provider offer technical support to enable successful transitioning to the newest qPCR reagent offerings whenever they become available?

5. What processes are in place to ensure minimal lot to lot variation of the reagents when generating data for a long-term study?

Top 7 Questions You Should Ask When Buying RNAi Reagents

1. Does the RNAi product provide transient silencing only or does it allow stable gene knockdown? Choice of RNAi products will be determined by whether you need to knockdown expression for several days or create a stable cell line.

2. Is the RNAi product suitable for your cells? How difficult it is to transfect your cells will determine the delivery method you require, such as tailored transfection reagent or lentiviral vector.

3. Ask if a ready-to-use product is already available; has the silencing of your gene(s) of interest already been validated and published?

4. Do the RNAi products guarantee a level of knockdown? What happens if you do not get the amount of gene silencing needed?

5. Are positive and negative controls provided with the RNAi products?

6. Does the RNAi product silence all known splice variants of my gene of interest and does it target the ORF or non-coding region of my gene?

7. How can I minimize the interferon response of RNAi transfection? shRNA instead of siRNA may be an option in some cases.
