About this work
Ribbon model of immunoglobulin Fc and fragment B of protein A complex. Protein A is a very stable surface receptor capable of binding the Fc fragment of immunogloblins, especially IgG. It can be coupled to reporter molecules such as fluorescent dyes, enzyme markers, colloidal gold and radiotracers to track immunoglobulins. Protein A can also be immobilised onto a solid substrate to aid the purification and recovery of immunoglobulins. <==================
