Peak Serum’s US Origin FBS (PS-FB1) seems to work great on Smooth muscle cells and human bone marrow mesenchymal stem cells (hMSC’s).

We tested both adipose derived MSC’s from mouse strains, one C57Bl/6 and one Luciferase transgenic mouse. Both cell lines did better with Peak Serum’s US OriginFBS, (PS-FB1) than Hyclone or Gibco.

We had the chance to test Peak Serum’s US Origin FBS (PS-FB1) side-by-side with the Gibco Certified brand we’re using and didn’t find any noticeable differences. I evaluated growth kinetics and tested to see if/how well the serums activated cell signaling pathways. I am happy with the results and quality of Peak Serum.

I tested a batch of FBS from Peak Serum in my microglial cell culture medium. The Peak FBS performed comparable to another product from a major supplier, and it worked great with my primary and cell line cells. I chose Peak’s FBS because of its performance as well as and their excellent customer service.
