Table 4: Elution ratios and estimated molecular weights of the DPPIV preparations.
| Wild-type MF | Wild-type CF | Omega MF | Omega CF | |
| VE/VO | 1.135 | 1.145 | 1.17 | 1.19 |
| Molecular Weight (kDa) | 256000 (4.7%) | 233000 (3.8%) | 212000 (7.6%) | 193,600 (10.2%) |
Each value is an average of 3 trials +/- (SE%)
For the purposes of Molecular Weight determination, the elution volume used to determine the Elution to Void Volume ratio (VE/VO) is the volume of the highest absolute enzyme activity.
