Description

Thermus aquaticus derived single-stranded DNA binding protein (SSB) is a thermostable protein which binds to single-stranded DNA with high specificity but does not bind well to double-stranded DNA (1). It plays important roles in DNA replication and recombination (2). Thermus aquaticus SSB gene was expressed in E.Coli in large quantities and the protein was highly purified. MW is 30.0 kDa, same as that of the natural protein.
