ALFA sdAb - FluoTag-X2 - List of all variants

A rationally designed epitope tag


This product was developed by   


Camelid single domain antibodies consist only of one antigen binding site of a Alpaca heavy chain antibody. With only ~15 kDa, these Tags are about 10-times smaller than conventional IgG antibody molecules. FluoTags carry fluorophore molecules coupled in a site specific manner.


The ALFA-tag is a novel, rationally designed epitope tag (SRLEEELRRRLTE) that forms a small and stable α-helix that is functional irrespective of its position on the target protein in prokaryotic and eukaryotic hosts.
