"A long time ago, in a building far, far away..." Randy designed some fancy barcodes for our BioBricks. Here's the URL describing the original plan. We've been building all our new ORF parts with barcodes for the last couple years.

Last week, with Heather's help, we ordered five sets of primers to finally test whether or not these barcodes work. Remember that the original purpose of the barcodes was to be able to provide a qualitative screen for whether or not a uncharacterized biological sample contains any BioBricks (or not). Nothing more fancy.

The five different primer sets are...

Barcode_A_for: 5' TAG TGC TAG TGT AGA TCA C 3'
Barcode_A_rev: 5’ TAC ACT AGC ACT ATC AGA G 3'

Barcode_C_for: 5' TAG TGC TAG TGT AGA TCC C 3'
Barcode_C_rev: 5' TAC ACT AGC ACT ATC AGC G 3'

Barcode_G_for: 5' TAG TGC TAG TGT AGA TCG C 3'
Barcode_G_rev: 5' TAC ACT AGC ACT ATC AGG G 3'

Barcode_T_for: 5' TAG TGC TAG TGT AGA TCT C 3'
Barcode_T_rev: 5' TAC ACT AGC ACT ATC AGT G 3'

Barcode_Internal_for: 5' CTG ATA GTG CTA GTG TAG ATC 3'
Barcode_Internal_rev: 5' GAT CTA CAC TAG CAC TAT CAG 3'

Today, with Jen's help, we both ran six PCR reactions (each single primer pair plus all four base-specific primers in a single mix). We used four templates: purified synchronator DNA, MC4100 cells containing synchronator plasmid, MC4100 cells (not containing any BioBricks), water.
