TESTIMONIALS

​

• My laboratory focuses on cancer biology and signal transduction, which can be sensitive to even the smallest variations in tissue culture conditions and reagents. Thus, our studies require high quality, consistent tissue culture products.
  We have been using fetal bovine serum (FBS) from Peak Serum, Inc. for a little over a year now and have found that the quality and consistency of the FBS to be superior over other sources that we have tried. Further, Peak Serum has provided fast and responsive customer service—they have been most helpful and have also provided very competitive pricing. We recently learned that Peak is now also carrying various laboratory disposables at great pricing and have placed our first order.

• Love this company! Peak Serum goes above and beyond when it comes to servicing their customers. I am always advised on what the best options are and made aware of any updates. I would definitely recommend shopping here for serum.

       R.B. Massachusetts General Hospital

• 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.

• I’ve used PEAK serum since I was a postdoctoral fellow and it’s a great product. All of our cell lines grow very well in it compared to other serum we’ve used and it’s priced very reasonable considering the high quality of the serum.

       L.C. University of Nebraska

• Great prices, fast shipping. A pleasure to work with Peak Serum and we have been using their FBS for 2+ years after switching from Atlanta Biologicals (much more expensive) and have not had any issues.

       D.M. Creighton University

• The US origin FBS from PEAK Serum (Cat #PS-FB1) works great for most of our cell lines. We have more than 20 different cell lines from different tissues culturing in the lab, they all grow healthily using PEAK FBS. I would recommend this FBS product as it provides superior quality while charged at a reasonable price.

• Tom Kutrubes is extremely knowledgeable, helping me find the appropriate serum for my cell lines at the best price, and quickly. The customer service couldn’t be better.

• Serum prices have been rising outrageously. It is difficult keep doing research when a big chunk of your grant goes to FBS. I have been searching for FBS alternative supplier to the most famous brand, taking a lot of time comparing different brands and lots of FBS for performance on our cells. We use mostly primary cells that we isolate from Epidermolysis Bullosa and Squamous Cell Carcinoma Patients, so the quality of FBS is capital importance for our purposes.
  It has been almost 3 years that we are using FBS from Peak Serum, Inc. It always has performed at the same levels, and in some assays even better, compared to FBS from other more famous brands, and the price is reasonable. Moreover, the costumer’s service is highly qualified, professional and collaborative.
  I highly recommend Peak Serum for its performance and for the knowledgeable and courtesy of the customer’s service.

• I have been working with Peak Serum for about one year and half and I have been extremely impressed. Their customer service is the best. I get a response to my email immediately and all my questions get answered clearly. When I order products, I get them in lab at a time that is convenient for me (and usually hand delivered! AWESOME!). The performance of my HepG2 cells with US Origin FBS (PS-FB1) compared to other competitor’s products can’t beat. And what a great deal on their prices!

• 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.

       A.H. University California San Diego

• 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.

       A.J. St. Jude Children’s Hospital

• 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.

       B.R. Duke University

• 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.

       C.L. H. Lee Moffit Cancer Center

• 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).

       D. R. Johns Hopkins University

• Great prices, fast shipping. A pleasure to work with Peak Serum and we have been using their FBS for 2+ years after switching from Atlanta Biologicals (much more expensive) and have not had any issues.

• We were satisfied with Peak Serum’s US Origin FBS (PS-FB1) for Mesenchymal Stem Cells, early incubation stage, obtained from bone marrow or fat tissue.

       E.B. ProgenCell Stem Cell Therapy

• 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.”
