    SuperScript III Reverse Transcriptase (RT) is active at 50°C and has a half-life of 220 minutes, providing increased specificity with gene-specific primers (GSPs) and the highest cDNA yield of all RTs. It is ideal for RT-PCR of a specific gene or for generating cDNA from total or poly (A)+ RNA samples. Like SuperScript II, it synthesizes a complementary DNA strand from single-stranded RNA, DNA, or from an RNA:DNA hybrid. SuperScript III RT is genetically engineered by the introduction of point mutations that increase half-life, reduce RNase activity, and increase thermal stability.

    • Thermostability: half-life of 220 minutes at 50°C
    • Yield: reduced RNase H activity for more full-length cDNA
    • Specificity: full activity at 50°C for increased specificity with gene-specific primers
      ·Applications—array labeling, cDNA libraries, RT-PCR, primer extension, 3' and 5' RACE
    • Source: Purified from E. coli expressing the pol gene of M-MLV, mutagenized to increase thermal stability and half-life and to reduce RNase H activity
    • Performance and quality testing: SDS-PAGE purity; endodeoxyribonuclease, exodeoxyribonuclease, and ribonuclease assays; and yield and length of cDNA product
    • Concentration: 200U/µL

    • Unit definition: One unit of SuperScript III RT is the amount of enzyme required to incorporate 1nmole of deoxyribonucleotide into acid-precipitable material in 10 minutes at 37°C using poly(A)·oligo(dT)12-18 as a template·primer
    • Unit reaction conditions: 50mM Tris-HCl (pH 8.3), 40mM KCl, 6mM MgCl2, 1mM DTT, 0.5mM [3H]dTTP, 0.1mM poly(A), 0.1mM oligo(dT)12-18, 0.1mg/mL BSA, and enzyme in 50µL for 10 minutes at 37°C
    • Optimal reaction temperature: 50°C
    • Final product size: 12.3kb or less
