Protein antigens quaternary structure

Larue, K., Kimber, M.S., Ford, R., Whitfield, C. Biochemical and structural analysis of bacterial O-antigen chain length regulator proteins reveals a conserved quaternary structure. J Biol Chem 284 (2009) 7395-7403. [Pg.23]

After the IEF run, the gel is exposed to a solution containing the E Ab conjugate. The enzyme is chosen to convert a colorless substrate into a highly absorbing product. A colored band appears where the Ab binds its Ag. Reaction of proteins with SDS, needed in the second dimension of the 2D separation, results in a loose of the tertiary-quaternary structure of the antigen, so that Ab probably will not bind. [Pg.353]

Figure 3. Complete covalent structure of human J chain as determined by Mole et al. (1977) (reprinted with permission). Such a globular protein should possess numerous potent antigenic determinants. The relative difficulty of producing anti-J-chain antisera may well be related to the details of its quaternary association with polymeric immunoglobulins. Figure 3.
