Product Information

Description

ET SSB (Extreme Thermostable Single-Stranded DNA Binding Protein) is a single-stranded DNA binding protein isolated from a hyperthermophilic microorganism, which remains fully active after incubation at 95°C for 60 minutes. Due to the extreme thermostability, ET SSB can be used in applications that require extremely high temperature conditions, such as nucleic acid amplification and sequencing.

By adding ET SSB, specific amplification was accomplished in PCR using one to five primer pairs in incurring order (lanes 1-5). Lane 5C shows a PCR reaction using 5 primer pairs, with no ET SSB included (control reaction). Lane M: 100 bp DNA Ladder.

The HDA reactions were prepared with either single or two sets of primers to amplify the invE (A) and/or invA (B) from Salmonella typhimurium genomic DNA. Lane M: Low Molecular DNA Ladder; Lane A: invE gene; Lane B: invA gene; Lane AB: invE and invA genes with no ET SSB present; Lane AB**: invE and invA genes with ET SSB in the HDA reaction. ** the reaction contained ET SSB.
