LS63 · FastGene® Scriptase II cDNA synthesis kit with 5X buffer, DTT, dNTPs, RNase-free water, oligo(dT) primers, random hexamers and RNase inhibitor, 100 reactions

• M-MLV–derived reverse transcriptases for cDNA synthesis from RNA
• Available as reverse transcriptase with reagents, cDNA synthesis kit, or 5X ReadyMix, depending on the range
Additional information:
Sample profile: Low amounts of RNA, synthesis of long cDNA
Activity temperature: 37–42 °C (ReadyMix Scriptase II: reverse transcription at 42 °C only)
Maximum cDNA length: ≈12 kb
Applications: RT-PCR; cDNA synthesis for NGS library preparation
Available in four formats:
- Scriptase II cDNA synthesis reagents: reverse transcriptase with 5X buffer, DTT, dNTPs and RNase-free water; primers and RNase inhibitor to be supplied separately
- cDNA synthesis kit: additionally contains oligo(dT) primers, random hexamers and an RNase inhibitor; only the RNA sample needs to be added
- ReadyMix 5X: contains random hexamers, an RNase inhibitor and an auxiliary protein; add RNA and RNase-free water
- ReadyMix 5X with oligo(dT): same composition with additional oligo(dT) primers; add RNA and RNase-free water
Variant(s)
