Part:BBa_K1807000:Experience

Above is a photograph of the BBa_K1807000 Gibson Assembly Reaction transformation. Escherichia coli NEB 5 alpha cells were spread onto LB Agar Plates containing Chloramphenicol 34ng/mL, IPTG ng/mL, Xgal ng/mL.

For the Gibson Assembly Reaction we mixed 100ng of PCR-linearized (provided with the distribution) and EcoRI-digested pSB1C3 vector backbone together with 3 times the molar ratio of our Adapter BioBrick G Block dsDNA. We incubated the reaction at 50 degrees Celsius for an hour and then used 2uL (out of 20uL total) in a standard heat-shock transformation of chemically competent cells.

Result: We did not observe white colonies on the plate - thus we estimated the Gibson Assembly efficiency for this reaction to be 100%.

We have sequenced single three colonies (clones) from the plate.

Further Applications

iGEM York 2015 used this part as an expression vector and assembled multiple IPTG-inducible protein generators. This part collection was assembled with colony PCR products that were gel extracted and with synthesized dsDNA fragments (G Blocks).
