Construction of biobricks: The restriction products were evaluated on a 1% agarose gel (see figure 2).

Construction of biobricks: The three plasmids were purified according to the protocol (link to protocol). Following the purification of the plasmids, a restriction analysis was performed using SpeI enzyme (10U) and incubated at 37ºC overnight.

Construction of biobricks: Some colonies were picked from the transformation plates and made overnight cultures in liquid media.

Construction of biobricks: Following purification, all of the PCR product was digested with XbaI (60U) and SpeI (30U). The mixtures were incubated at 37ºC. After 8 hours of incubation, more enzyme was added (XbaI (20 U) and SpeI (10U)) to ensure maximum digestion. Following enzymatic purification a gel was run to estimate the concentration of the vector and the PCR product (see figure 1).

Figure 1: Electrophoresis gel picture of the PCR products of the three biobricks and the vector. The band 11P at 1500 bp corresponds to the vector; the three other bands at 537 bp, 207 bp and 125 bp correspond to the fragments Cln, GFP and Cln_GFP respectively.

To meet the 3:1 ratio of fragment to vector 12μl fragment was mixed with 2μl vector, 2μl ligase buffer (10x), 1μl ligase, 3 μl Mq H20. The ligation of the fragment and the vector was carried out on PCR machine using a 3:1 ratio for 1.5 hours using the idea by Lund, A. H., M. Duch, and F. S. Pedersen. 1996. Increased cloning efficiency by temperature-cycle ligation. Nucleic Acids Res. 24:800-801. doi:l50400 [pii]. The final product was finally transformed into competent E coli cells.
