Table 2.

Molecular weight (kDa) of gelatin from turbot skin in distributions shown in Figure 1. Rt: retention time; Mw: weight average molecular weight; Mn: number average molecular weight; PDI: polydispersity index. Peak area (%) corresponds to refractive index detector. Values are represented as mean ± standard deviations (n = 2), except for M4.
