Analysis of crystals of the 2C TCR. (A) Large crystals of 2C (B) SDS/PAGE analysis (silver-stained) of a washed 2C crystal reveals crystal is composed entirely of αβ covalent heterodimer. (C) IEF of a washed 2C crystal indicated that the predominant charge isoforms from the starting material are present in the crystallized protein. (D) Inspection of the crystal lattice packing of the 2C TCR crystals indicates that the α and β chain C termini of 2C are in contact with symmetry-related molecules.
