Results
Serum(-):
Serum(+):
→ bad measurement, no binding curves were obtained
→ signal for 1:10 dilution of the blood serum much better → continue with 1:10 dilution

| StrepCy5 | 8 | 30 | 600 | 5 ug/ml |
| Buffer | 9 | 60 | 300 | 1x |
Results
Serum(-):
→ higher dilution of the blood serum leads to weaker iRif signal for mCherry, BSA,BSA+bBSA and bBSA but also for the tetanus antigen
Serum(+):
→ higher dilution of the blood serum leads to weaker iRif signal for mCherry, BSA,BSA+bBSA and bBSA but also for the tetanus antigen
→ signal of the tetanus antigen spot very weak compared to experiment 59a → use fresh stock of tetanus antigen next time
→ unspecific binding to the BSA spot is most of the time weaker than to mCherry → from now on BSA will be used as negative contol for blood serum

2015.09.02
Experiment/Protocol
Flush protocol:
| Reagent | Step | Flow rate (ul/min) | Priming time | Concentration |

| Buffer (TBS) | 9 | 60 | 300 | 1x |
last slide (208) changed protocol: only 1 ug/ml anti-GFP used; anti-Salmonella desalt was mixed 1:1 with anti-Salmonella lysate
Results
Note: Slide 208 had the best signal.
