pSpark® IV DNA Cloning Kit

pSpark® IV DNA Cloning Kit

For highly Efficient, Stable & Powerful Cloning under transcription-free conditions

Product Overview:

pSpark® IV is a highly efficient, accurate and easy-to-use DNA cloning system that exploit its very low background feature for the expression of toxic genes under transcription-free conditions. In this vector, the lac promoter has been eliminated and therefore blue/white screening is not allowed (alpha-peptide coding region remains and you can find blue colony). The vector is ideal for cloning genes that produce toxic polypeptides by transcription/ translation.

Advantages & Features

  • Unprecedented high cloning efficiency: more than 2,500 positive colonies expected under optimal conditions.
  • Transcription-free.
  • Easy-to-use: eliminate screening of recombinants due to its minumum background (lower than 1%).
  • High stability: eliminates cloning bias or pitfalls.
  • Time-saving protocol: avoids any step required after PCR, just 19 minutes from PCR to plating.
  • Powerful: obtain 5-fold more positive colonies using 10-fold less DNA insert.
  • Great versatility: compatible with any protocol, proofreading Polymerase, Competent Cells, ligation time or primers.
  • Sensitive: clone from 50 bp insert to up to 14 kb with just 5 ng per kb of insert.
  • Cost avoidance: removes expensive primer phosphorylation use.
  • Eliminates positive selection vector.
  • Risk-free: product covered by our Quality 100% Guarantee.

Advice

  • 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: -20º C (NON Frost-Free Freezer).
  • Shelf Life: 24 months from the date of purchase, if it is properly stored.
