Abstract:

A method based on single molecule experiment was adopted. Single-molecule magnetic tweezers was used to study the different binding process of SSB(E. coli single-stranded DNA binding protein) and ssDNA(single-stranded DNA) in different conditions, and get the reaction rate and reaction detailed information. This method can be used in similar reactions.

Key words: Reaction rate, Reaction dynamics, Single-molecule magnetic tweezers, Single-stranded DNA binding protein
