    Double Digestion with NEBcloner
SphI has a High Fidelity version SphI-HF® (NEB #R3182).

High Fidelity (HF) Restriction Enzymes have 100% activity in rCutSmart Buffer; single-buffer simplicity means more straightforward and streamlined sample processing. HF enzymes also exhibit dramatically reduced star activity. HF enzymes are all Time-Saver qualified and can therefore cut substrate DNA in 5-15 minutes with the flexibility to digest overnight without degradation to DNA. Engineered with performance in mind, HF restriction enzymes are fully active under a broader range of conditions, minimizing off-target products, while offering flexibility in experimental design.
Product Source
An E. coli strain that carries the SphI gene from Streptomyces phaeochromogenes (NRRL B-3559).
