Hypothesis
The activation energy requirement for the electromigration of SDS-bound monoclonal antibody fragments in tetrahydroxyborate cross-linked agarose gels is molecular weight-dependent.
Conclusion
Larger SDS–protein complexes required lower activation energies for electrophoresis than their lower-molecular-weight counterparts.
Supporting Evidence
- The activation energy for larger SDS–protein complexes was found to be lower than that for smaller ones.
- Temperature changes affected the viscosity of the gels, influencing the activation energy requirements.
- Reproducibility of the electrophoresis results was confirmed across multiple runs.
Takeaway
This study found that bigger proteins can move through a gel more easily than smaller ones, which is the opposite of what we usually think.
Methodology
Capillary electrophoresis was used to separate SDS-protein complexes at different temperatures, and Arrhenius plots were employed to derive activation energy values.
Limitations
The study did not differentiate between the distortion effect on the sieving matrix and the deformation on the sample components.
