Table 4.

Comparison of absolute quantitation of total HA by SDS-PAGE and by label-free LC-MS/MS.

U3 U4 VG
HA concentration by SDS PAGE, μg/mL 62.30 88.91 68.13
HA concentration by LC-MS/MS, μg/mL 58.12 82.23 64.84
Relative difference, % 6.72 7.51 4.83

Note: Relative difference (%) is the ratio of the difference between total HA concentrations quantified with SDS-PAGE and with LC-MS/MS to total HA concentration quantified with SDS-PAGE.
