T4 Gene 32 Protein is a single-stranded DNA-binding protein required for DNA replication and repair in T4 Phage. It coordinately binds and stabilizes the ssDNA region that transiently forms, and plays an important structural role in the T4 Phage DNA replication. The protein has also been widely used to stabilize and label ssDNA regions in order to observe intracellular DNA structure with an electron microscope. The latest reports have shown that T4 Gene 32 Protein can promote digestion of restriction enzymes, improve the efficiency of reverse transcription in RT-PCR, enhance the activity of T4 DNA polymerase and increase the yield of PCR.
