E. coli single-stranded DNA binding protein (SSB) binds to single-stranded DNA with high specificity (1, 2). It is involved in DNA replication and recombination in vivo. The SSB gene was expressed as the recombinant protein in E.coli highly purified. The molecular mass is 18.9 kDa.
Greater than 95% purity as determined by SDS-PAGE (CBB staining)
The absence of endonucleases and exonucleases was confirmed.
[Molecular Mass]
18.9 kDa
[Data Link]
