Hypothesis

Can a novel protein design reduce the dissociation of mouse monoclonal IgG from a protein array?

Conclusion

The introduction of a flexible linker between Z domains increases the capacity for IgG binding, enhancing the signal and sensitivity of the array.

Supporting Evidence

  • The engineered protein showed improved binding of mouse monoclonal IgG compared to previous designs.
  • Surface plasmon resonance confirmed the successful assembly of the protein on gold.
  • The flexible linker allowed for better interaction with antibodies, increasing binding capacity.

Takeaway

Scientists created a new protein that helps mouse antibodies stick better to a surface, making tests more reliable.

Methodology

The study involved engineering a scaffold protein with Z domains linked by a flexible polypeptide linker and testing its binding properties using surface plasmon resonance.
