(EMSA technique overview)
EMSA is a biochemistry method to test the specific binding of proteins to DNA fragments.
Basic steps for EMSA assay include:
1. DNA labeling with radioactivity or non-radioactivity.
2. Form Complex by mixing DNA and protein in an reaction.
3. Add nonspecific competitor in reaction to compete for the binding between DNA and protein.
4. Run native gel to separate complex with free probe.
