Plasmid 34917: pBCN42-R4R3
  • None

  • Worm Expression

  • Spe I, Xcm I, Bgl II, Avr I and Sac I restriction sites introduced into backbone for linearisation, if necessary. The ccdB gene was replaced with a version from pDONR221 (Invitrogen) that is compatible with commercially available ccdB Survival E. coli, no longer requiring DB3.1 cells.

  • Ampicillin and Chloramphenicol

  • ccdB Survival

  • 37

  • As a Gateway destination vector the empty vector must be grown in ccdB resistant cells such as DB3.1 or ccdB Survival. Use both Ampicillin and Chloramphenicol selection to avoid loss of the Gateway cassette. Once the Gateway cassette has been replaced with the gene of interest select with Ampicillin in standard E. coli strain such as Top10 or DH5alpha.

New version of Puromycin resistance vector for drug selection in worms.
This vector replaces pBCN21-R4R3 (main advantage of the new vector is compatibility with ccdB Survival cells).
This is a Gateway 3-fragment compatible destination vector. It contains AttR4 and AttR3 sites (not AttR1 and AttR2 sites as identified automatically by the Addgene algorithm).

Addgene has sequenced a portion of this plasmid for verification. Full plasmid sequence is available only if provided by the depositing laboratory.
