Sample name is what will ultimately label your DNA sequence data file. Maximum 8 characters. (2). Amount of template. We require 8µl DNA per reaction containing appropriate amount of DNA. (If possible try to send 9-10 l of the template per reaction) -Please follow these guidelines: Template DNA Plasmid Size 3 - 10 kb 10 - 20 kb Quantity 0.2-0.5 µg / 8µl 0.4-0.6 µg / 8µl Cosmids 30 - 45 kb 0.2-0.4µg / 8µl BACS 80 - 300 kb 0.25-0.5µg / 8µl 3 - 10 kb 100 - 200 bp 200 - 500 bp 500 - 1000 bp 1000 - 2000 bp >2000bp 0.1µg / 8µl 1-3 ng / 8µl 3-10 ng / 8µl 5-20 ng / 8µl 10-40 ng / 8µl 20-50ng/8ul M13 ssDNA PCR products (3). Please supply Primer: Volume = 10µl per reaction @ Concentration = 0.8-1.0 pmol / µl. Primers should be at least 18 bases long with a T m of 55-60oC and have sequences without runs of identical bases or self complimentarity. PNACL has stocks of the following primers to be used with appropriate templates, free of charge. If you wish to use these, please indicate by ticking the boxes next to the primers.

Recommended quantification method is by agerose gel against known concentration of a Lamda ladder. General growth condition • LB medium (Terrific broth and other rich media should be avoided) • Cells should be grown to OD600nm of 1.5 to 4 units- typically for 12-16 hours • If possible, use vectors with high copy numbers e.g. pUC / Bluescript / pGEM • Host strain - avoid JM100 series, TG1 & TG2 - as these strains contain high carbohydrate level.
