• General cloning.
• Clone PCR fragments included in a low amount.
• Cloning of PCR products amplified with High Fidelity polymerases.
• Cloning of PCR fragments generated with a blend of polymerases.
• Production of ssDNA.
• Blue/white screening for recombinants.
• In vitro transcription from T7/SP6 dual-opposed promoters.

t

• Functional test using a 1.0 kb PCR fragment.

• Recommendations: All pSpark® DNA cloning vectors are stable for at least 1 month at 4 °C and even at 20 – 25 °C for up to 2 days although storage temperatures above -20 °C are not recommended. In case of incident, such as a power failure, stored vectors should be tested with the supplied control insert before considering discarding it. However, please note that T4 DNA Ligase is extremely temperature-sensitive and storage temperatures above    -20 °C inactivates the enzyme.

• Shipped in: Gel pack.
• Storage: -20 ºC (NON Frost-Free Freezer).
