pSpark® TA

For Efficient, Stable & Easy cloning of non-proofreading PCR fragments or PCR from a blend of enzymes

pSpark® TA is efficient, stable and easy-to-use DNA cloning vector based on an optimized TA technology for cloning single 3 ́-adenine overhanging DNA. The vectors are prepared by digestion of pSpark® TA at EcoRV site and the subsequent addition of a single thymidine at each 3 ́- end to allow cloning Taq DNA Polymerase amplified DNA fragments. Its exclusive procedure offers greater efficiency and less background of blue colonies than the others TA vectors.

Detailed information:

Advantages & Features
  • Efficient: more than 600 white positive colonies expected under optimal conditions.
  • Easy-to-use: eliminates screening of recombinants due to its low background (4%).
  • High stability: vector without cloning bias due to transcription of toxic genes.
  • Fast protocol: ligation time from 60 minutes to overnight.
  • Compatible: with direct cloning of PCR products.
  • Great versatility: compatible with any competent cell, primer design or particular proofreading DNA Polymerase.
  • Cost avoidance: avoids primer phosphorylation.

Tables & Figures


Quality Control
  • Functional test using a 600 pb 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.
Storage, Shipping & Guarantee
  • Shipped in: Gel Pack.
  • Storage: -20 ºC (NON Frost-Free Freezer).
