I have been using Peak Serum since starting my graduate studies almost 3 years ago. Earlier this year, we tested FBS lots from other vendors & from Peak Serum as we were looking to purchase a new batch. The representative was very easy to work with and knowledgeable about which lots were available & how they would perform. He knew right away which samples to send over that would work best for the mouse embryonic stem cells we culture. He wasn’t wrong! The samples he sent over out-performed the lots from other vendors and the price matched the quality.
