Jump-distance analysis at different lag times. (A) BR2 mRNP jump-distance distribution from frame to frame. a.u., Arbitrary units. (B) Jump-distance distribution from frame i to i + 10. (C) Jump-distance distribution from frame i to i + 20. (D) Jump-distance distribution from frame i to i + 30. A satisfactory fit to the data required 3 mobility components, from which the fraction sizes and the diffusion coefficients were extracted. The broken lines quantify the contributions of the three mobility fractions, whereas the solid line represents their sum.
