Cloning Brachyury from SW480 in pNEB193 plasmid - Essay Exampleigure 2 The total ribonucleic acid was extracted from SW480 cells by map of Norgens Total RNA Purification Kit, the samples were then denatured in rapid Formalin free RNA loading buffer which had Formalin detached RNA dye. They were then incubated for 5 minutes at a temperature of 700C. Lane number one was filled with RNA ladder 5 L. The lanes from number 2 to 20 contained 10 L of each of the class samples. The image capture was then done using GelDocEZ system.3-Table 1 The concentration and purity of the total extracted RNA from the SW480 cells for the sample H was is shown in table 1. The resulting concentration of RNA was 82.88 ng/ul. An RQI of 7.3 indicated that the RNA quality was accepted. The ratio (28S/18S) was 0.93 though the recommended ratio is 2The plasmid readying experiment was undertaken before the start of the RNA extraction. The purpose of this experiment was to purify enough linearized phosphatise t reated pNEB183 plasmid to be apply in the ligation reaction. This catharsis was win through several steps that started with the purification of the inoculated plasmid from E.coli culture in LB/ampilicin broth. Using Qubit analysis, the concentration of the purified plasmid was calculated to be 5.1 ul. The EcoR1 enzyme was then utilised to digest the circular plasmid into a linear plasmid which was then treated using alkaline phosphatise enzyme to remove the 5 phosphate group and halter self ligation. The sample was then loaded on 0.8% agarose gel so as to visualize and purify the linearized plasmid from the gel by use of purification method as shown in figure 5In figure 5, two bands were clearly seen in the back up lane. The first band was an uncut plasmid. The second band was a linear plasmid. Adequate preparation took place as the linear plasmid could migrate longer on the gel. The second band was silver and shiny. It was 2797 bps in length. It also contained ...ul/mg conce ntration of plasmid. Using x tracta Gel Extraction
