Topics taught in each lab.
| Lab | Lab topic | Description |
|---|---|---|
| 1 | Bacterial growth | Spectrophotometer is used to determine the turbidity and therefore concentration of batch-cultured E. coli at specific time points followed by formulation and interpretation of bacterial growth curve. |
| 2 | Bacterial transformation | E. coli are made competent using CaCl2 and heat shock technique and transformed using a recombinant plasmid. Cells are then cultured on agar plates to verify transformation using antibiotic resistance imparted by the plasmid. |
| 3 | DNA isolation and Purification | Transformed E. coli are used to isolate plasmid using an alkaline lysis assay and the plasmid concentration and purity is determined by performing gel electrophoresis. |
| 4 | Restriction Digestion | The isolated plasmid is subjected to restriction digestion using 2 separate restriction endonucleases or their combination. Gel electrophoresis is performed to assess the properties of digested and undigested plasmids. |
| 5 | Protein Quantification | A Bicinchoninic acid (BCA) assay and UV absorbance method is employed to determine the concentration of unknown proteins. |
| 6 | Protein purification | Affinity chromatography is used to purify and elute proteins isolated from bacterial cell culture. |
| 7 | Protein Concentration | Centrifugal filtration method is used to concentrate the isolated proteins from lab 6 which are then quantified using BCA assay. |
| 8 | SDS-PAGE | The concentrated samples from Lab 7 are separated using Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and assessed. |
