T4 gene 32 protein (Single-stranded DNA binding protein, SSB)

Cat No: FNK-02-040

Storage: -20°C
Size: 200µg

Description 

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. 

Applications

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

Quality Assurance

Greater than 95% of protein determined by SDS-PAGE (CBB staining) The absence of endonucleases and exonucleases was confirmed.

Form

10 mg/ml in 20mM Tris-HCl (pH 8.0), 100mM NaCl, 0.5mM dithiothreitol, 1mM EDTA, 50% glycerol
