Why Choose Biomatik?

Biomatik has been trusted among top scientists and researchers from around the world for quality products and custom services since 2002.  Please view our customer testimonials below and over 2,000 publications citing our fine products & services at Google Scholar.

"Our main concern is both of them are hydrophobic with very limited solubility. Biomatik started the protein production process from codon optimization and gene synthesis, the solubility of proteins we got were significantly improved. When we applied these proteins to our ELISA diagnostic assay, they all keep showing highly specific reactivity and very low background. We are very satisfied with the qualities of these proteins. Biomatik run the whole processes very efficiently and we always get our proteins quickly. Their customer support also works well with many helpful professional advices. So we strongly recommend the protein preparation service of Biomatik. Thanks again for your good job."

“We are very satisfied with the polypeptide antibodies you produced for us. They work great for both WB and immunostaining (so far we tested). They are very strong and specific (for WB, I can use at 1:5k-10k dilution). Previously we had bad experience with peptide antibodies from other companies. This is the first time we have nice peptide antibodies. In addition, I like your service and time frame. Also your price is reasonable. I think I will continue use your service in the future.” 
Dr. Hong Han, Dept. of Biology, McGill University, Montreal, Quebec, Canada
