“I was delighted to find such a great selection of aminodextrans of various sizes and amine/dextran ratios offered by Fina BioSolutions.  Taking advantage of this comprehensive toolbox allowed us to quickly improve the signal to noise ratio of our assay by an order of magnitude. Aminodextrans offered by other vendors have lower content of amino group and, hence, do not show robust performance in our assay.  These products fully met out hopes and I look forward to working together in future.”

“I am very happy to have found Fina BioSolutions, which can supply amino dextrans and amino Ficolls with a wide range of well-defined molecular weights and amine ratios. Also, I am interested in Fina BioSolutions mono-substituted amino dextrans. I am looking forward to using your products in our applications.”
