Table 5.
Protein-binding affinities of CT fractions of different molecular weights using bovine serum albumin (BSA) as reference protein.
| Fraction | Molecular weight (Da) | b value 1 |
|---|---|---|
| F1 | 1265.80 | 0.216 ± 0.025 a |
| F2 | 1028.60 | 0.295 ± 0.036 b |
| F3 | 652.20 | 0.359 ± 0.049 c |
| F4 | 562.20 | 0.425 ± 0.022 d |
| F5 | 469.60 | 0.460 ± 0.048 d |
a–d Means within a column with no common superscript differ significantly (p < 0.05). 1 b value is the CT quantity (mg) that is needed to bind half of the maximum precipitable BSA. It is used to denote the protein-binding affinity of CTs in this study. When b value is smaller, the protein-binding affinity of the CTs is stronger.
