Troubleshooting
- After crosslinking/labeling, my protein of interest precipitates out of solution. What can I do?
- I used a previously prepared stock solution of the crosslinker but the crosslinking efficiency was low. What can I do?
- I attempted to crosslink/label my protein of interest but the labeling reaction was unsuccessful, what can I do?
- How can I test the reactivity of my NHS ester biotinylation and crosslinking reagents?
- How can I remove excess crosslinker or labeling reagent from my sample?
