Why isn’t there anything visible in the vial containing the dry GenePORTER reagent?
The GenePORTER reagents are provided as a dry lipid film to increase long-term stability. The lipid film is essentially invisible to the naked eye, but it is there. Just hydrate the product as instructed in the protocol. (NOTE: In the event that the hydration buffer is accidentally spilled or missing, sterile tissue culture grade water can be substituted).
