Practical issues - Analytical ultracentrifugation service

Samples:

  • Protein concentration: 1-2 mg/ml

Volume:

  • 400 ul for sedimentation velocity (SV) experiments
  • 100 ul for sedimentation equilibrium (SE) experiments

Buffer:

  • phosphate buffered saline (PBS) if possible
  • ionic strenght: always use > 10 mM NaCl or other salt
  • try to avoid the use of glycerol and sucrose
  • low amounts of HEPES, Tris, DTT is allowed

Other requirements:

  • protein sequence including any tags/extra residues after cleavage (.txt)
  • protein mass corresponding to the sequence
  • PDB code, if available
  • composition of the buffer

Limitations:

  • Size range: 100 Da - 108 Da
  • KD: pM – mM
