Steps:

1. Usefull links (restriction enzymes)(Software)<open wetware primer design> <more primer design>
2. Sequences:
   1. Ncbi genebank AF053765 (pNL26 7371bp) (pNL29 6036bp) [http://www.ncbi.nlm.nih.gov/entrez/viewer.fcgi?db=nuccore&id=3089519| (original source)] (FASTA seq.)
   2. pBluescriptIIKS+ [http://www.stratagene.com/products/displayProduct.aspx?pid=267 (stratagene) ][http://www.stratagene.com/vectors/sequences/pbl2ksp_s.txt (sequence) ] [http://www.stratagene.com/vectors/restriction_sites/pbl2ksp_r.txt (restriction map) ][http://www.stratagene.com/vectors/maps/pdf/pBluescript%20II%20KS+_%20webpg.pdf (map) ] [http://www.stratagene.com/manuals/212205.pdf (Manual)]
      • (no spaces sequence 2961bp)
      • HindIII cuts at 719 ,EcoRI cuts at 707 ,PstI cuts at 701 ,Xbal cuts at 677 ,SpeI cuts at 683

   3. pNL26 Plasmid with insert: (seq 10318bp) (res map) (digests) (reverse complement)
      1. pNL26 insert PstI--HindIII:(pNL26 7371bp)
   4. pNL29 Plasmid with insert: (seq 8983bp) (res map) (digests) (reverse complement)
      1. pNL29 insert PstI--HindIII:(pNL29 6036bp)

1. Recovery of genes: (2 days)
   1. Recover the plasmid from paper provided into solution.(method)
   2. Transform E.Coli strain DH5alpha. Screen with Amp 100ug/ml (as per ref.)(electroporation & heatshock)
   3. pick 3 colonies of each
   4. Overnight Culture x9(6 above and 3 form agar block provided)
   5. Miniprep
   6. Produce glycerol stocks
   7. Confirm presence in recovered sample using digest.(HindIII)
   8. ->Established Supply of Plasmid
