Some programs call for the dextran tracer be addressed with formaldehyde or glutaraldehyde for subsequent analysis. For these purposes, we provide “lysine-fixable” variations of almost all of our dextran conjugates of fluorophores or biotin. These dextrans have covalently sure lysine residues that permit dextran tracers being conjugated to encompassing biomolecules https://franzz581eil7.vidublog.com/profile
