The recombinant heavy-chain anti-ALFA antibody is a genetic fusion of our established camelid anti-ALFA single-domain antibody (sdAb) to various IgG Fc domains of the most commonly employed host species. This antibody preserves the specificity and high-affinity binding of the anti-ALFA single-domain antibody and adds the features of a conventional IgG type antibody. It can be used in Western blotting and many other applications based on immunodetection (IF, IHC, IP).
