NDSB-221 - 5 g

- Efficiently solubilizes proteins at non-denaturing concentrations
-Useful in preventing protein aggregation
- Non detergent sulfobetaines (NDSB) are used for protein folding, renaturation and crystallization
- Protein specific additive for solubility and stability

The NDSB are a group of zwitterionic compounds that can reduce aggregation and aid in refolding proteins found in inclusion bodies and bacterial expression systems.

Non detergent sulfobetaines have a sulfobetaine hydrophilic group and a short hydrophobic group that cannot aggregate to form micelles, therefore NDSB’s are not considered detergents. NDSB increase the extraction yield (up to 30%) of membrane, nuclear and cyto-skeletal associated proteins. The short hydrophobic groups combined with the charge neutralization of the sulfobetaine group results in higher yields of membrane proteins. NDSB have been used in refolding and renaturation of chemically and thermally denatured proteins.

Typical useful NDSB concentration in protein sample is 0.5-1.0 M.
