E. coli Single-stranded DNA Binding Protein (SSB)


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.


1) Functional single-stranded DNA-binding protein for studying DNA replication and recombination
2) Enhancement of the specificity and yield of PCR

Form: 5 mg/ml in 20mM Tris-HCl (pH 7.6), 200mM NaCl, 1mM dithiothreitol, 1mM EDTA, 50% glycerol
Quality: Greater than 95% purity as determined by SDS-PAGE (CBB staining) The absence of endonucleases and exonucleases was confirmed.
Data Link: Swiss-Prot P0AGE0
Storage: Store at -20°C

0.02 ug/ul of M13mp18ssDNA was incubated with 0 (lane0), 0.025 (lane1), 0.05 (lane2), and 0.1 (lane3) ug/ul of SSB at 37oC for 30 min. and then 10ul aliquot was subjected to electrophoresis in agarose.
