MGFP-5 BCA Protein Quantification Assay
This assay tests for the presence of mgfp-5 displayed on the surface of E. coli through its ability to bind to the bottom of polystyrene plates.
Constructs used:
- mgfp-5 + spacers + displayers (79)
- mgfp-5 + displayers (14)
- displayers only (15)
Experiment run with 5x replicate of each condition
Day 1: Grow Cells
- Pick cells, using pin tool, with appropriate constructs from frozen stock plates into 96-well blocks with 1 ml of LB+AC media
- Place blocks in 37C shaker overnight to grow to saturation
Day 2: Induce Cells
- Set up 96-well blocks with 1 ml of LB+AC+arabinose media:
- Add 1 ul of arabinose at a concentration of (100mg/ml) to one ml of LB+AC media (1: 1000)
- Take plates with constructs out of the 37C incubator and add 10 ul of each construct to the LB+AC+arabinose media to induce
- Incubate blocks at 37C in shaker overnight.
Day 3: Incubate in Artificial Seawater
- Remove blocks from incubator
- Pellet cells at 5400 rpm for 7 minutes
- Remove supernatant by flicking block over a sink (swiftly inverting block in one motion)
- Re-suspend cells in 100 ul of artificial seawater
- Transfer 50 ul of cell suspensions with multi-pipette to labeled flat bottom 96-well costar plates (polystyrene plates)
- Cover plates with plastic film and let cells settle overnight
