T4 Gene 32 Protein (Single-stranded DNA Binding Protein, SSB)


T4 gene 32 protein is a single-stranded DNA binding protein from phage T4 which binds to single-stranded DNA with high specificity (1, 2). It is involved in DNA replication and recombination. The T4 phage-derived SSB gene was expressed in E.coli and the protein was highly purified. MW is 33.5 kDa.


1. Promoting DNA replication and recombination by stabilizing single-stranded DNA (1)
2. Increase specificity and yields of long PCR products (3)

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 37°C for 30 min and then 10 ul aliquot was subjected to electrophoresis in agarose.
