Why are there particulates in my sample of Animal-Free Blocking Solution (5X) #15019?

Particulates may occasionally be seen in our Animal-Free Blocking Solution (5X) #15019 due to material becoming caught in the threads of the cap/bottle and drying out over a short period of time. These particulates are of no cause for concern and you may continue to use and dilute the product to the 1X working concentration. You may also heat the product at 37C for 15 minutes to help bring any material back into solution, if required.
