What concentrations should TCEP and IAA be used for protein reduction and alkylation?
1. TCEP:
Commonly used to reduce disulfide bonds in proteins. The typical concentration ranges from 5 mM to 10 mM. It's important to note that the final concentration of TCEP may be adjusted according to the specific needs of the experiment and the characteristics of the protein.
2. IAA:
Used for alkylating reduced free thiols to prevent the reformation of disulfide bonds. The typical concentration of IAA ranges from 15 mM to 50 mM. Similarly, the specific concentration may need to be adjusted based on the specific conditions of the experiment and the properties of the protein.
In practical applications, ensure that the concentrations of TCEP and IAA are suitable for your specific experimental needs, and avoid exposure to light and oxidation during the handling of these chemicals.
