WebFeb 1, 2024 · The Kratky plot, I(q)*q 2 vs. q plot, is thus informative to check globularity and flexibility of your protein. In the case of well-folded globular protein, the Kratky plot will exhibit a "bell-shape" peak at low q and converges to the q axis at high q. The Kratky plot will not converge to the q axis if the protein has a pronounced flexibility.
