    The differentiation assays are finicky about the serum we use and our findings indicate that Peak Serum’s US Origin FBS (PS-FB1) can be used in conjunction with osteogenic and osteoclastic cytokines for differentiation and maturation assays respectively.

    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 compared the growth of three different primary fibroblast lines in media supplemented with Peak Serum’s FBS to their growth in media supplemented with four other commercially-available FBS samples and noticed a big difference in growth or cell morphology by phase microscopy when using Peak Serum’s FBS.

    Our laboratory utilizes primary adult stem cell lines from multiple species, adult and embryonic primary fibroblasts, and commercially available immortalized cell lines. Peak Serum’s FBS allows us to maintain our normal growth rates and morphology compared to serums from GIBCO and HyClone, but at a more budget friendly cost. We greatly appreciate the customer service Peak Serum provides and highly recommend the company and its product.

    I have used Peak Serum US FBS (PS-FB1) in comparison with other serum brands for the isolation of primary human keratinocytes and fibroblasts. Primary keratinocytes colonies growth assay showed that Peak serum was among the best, as well as for primary human fibroblasts isolation and growth.

    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.

    Our test of the low endotoxin US FBS from Peak Serum ( PS-FB1) on human monocytes through measurement of cell viability, and TNFa and IL1b cytokines production by ELISA, shows that Peak Serum FBS supports the culture and performance of the cells similarly to the FBS previously used in our lab.

    Considering HT-1080 fibrosarcoma, Peak Serum US FBS lot was better than 5 other leading FBS brands including our current control.

    Furthermore, considering the price of Peak Serum US FBS lot, which was up to $100 lower per 500mL bottle than the other brands, along with equivalent or better performance, Peak Serum was a clear winner!

    Another very important consideration was that Peak Serum accommodated our request of spreading the payment of the whole purchase for 6 month, which was crucial for making a final decision.”

    Peak serum provides US origin and USDA approved fetal bovine serum that is superior in quality and less expensive. We have tested other brands of serum alongside Peak FBS and found it to be a better product overall. Better quality product at a lower price relative to competitors.

    Our cells grow at the same rate with your FBS as compared to our current batch, and exhibit basically the same levels of mRNA for various markers that we are interested in.

    As a member of a large lab and having a tight timeline to test and order FBS, Peak Serum helped meet my needs quickly, efficiently, and competitively. They gave me a competitive price up front, shipped me a sample to test quickly, and had sera that worked competitively side by side other samples. The personal touch and attention was the best part. I will surely be in touch for future needs!

    Our lab has been very pleased thus far with the FBS that Peak Serum provides.  The quality of the FBS has been excellent, and we have seen consistent cell growth and gene expression in our tissue culture samples.  The FBS has always arrived in excellent condition and well packaged.  We have been particularly pleased with Peak Serum’s customer service and their willingness to provide samples at no cost.  Tom is very professional and responsive to our laboratory needs.
