Biochemical and Physiological Mechanisms
Beta-crystallin A4 (CRYBA4) is a member of the beta/gamma-crystallin family which are the dominant structural components of the vertebrate eye lens. Beta-crystallins construct aggregates of various sizes and are able to self-associate to form dimers or to
24.6 kDa, under reducing conditions; 20.0-25.0 kDa, under non-reducing conditions.

Recombinant Human CRYBA4 Protein (rp189339) - SDS-PAGE
3 μg/lane of Recombinant Human CRYBA4 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing the bands at 24.6 kDa under reducing conditions and 20.0-25.0 kDa non-reducing conditions.
The presence of not only one band under non-reducing conditions may be due to the protein existing in different conformations in this state (Uniprot: P53673).
