Research and Biotech labs use centrifugal devices for antibody and protein concentration and purification. This can include desalting, buffer exchange as well as protein removal from peptides and other small molecules. NoEndo gel products are used to remove endotoxins from protein solutions for research and biological production applications. These proteins may be derived from recombinant bacteria as well as mammalian cells. Vivaproducts also supplies pipettes and centrifuges for use with our concentrators or for general laboratory purposes.
