Part:BBa_K608013
strong Promoter with strong RBS and RFP
This part consists of a strong promotor with strong RBS and tagged with RFP to quantify the expression.
The RFP fluorescence was measured with a plate reader:
The fluorescence intensity and protein concentration were measured with the FLUOstar Omega, which is a multi-mode microplate reader.
Samples were pipetted into the microplate and analyzed via the plate reader. In this experiment we focused on the protein concentration and the fluorescence intensity of RFP.
We measured the protein concentration with the bradford-assay. This is a method to determine the total protein
To analyze the protein concentration of the samples, Coomassie Brillant Blue was pippeted to each sample. With the binding of the dye to the proteins the color changes from dark red to blue. The more protein in the solution the more Coomassie dye can bind to proteins and the more the color changes into blue. The absorption of bound Coomassie dye is 595nm. The absorbance is proportional with the amount of bound dye. With a series of Bovine Serum Albumin (BSA) measurements the exact protein concentration of the samples can be determined. BSA acts like a “marker†because the concentration of BSA is known and with a linear calibration line the exact protein concentration can be detected.
