Aim: This step checks the ability of our protein to bind cellulose. Moreover, this step will confirm the good design of the protein.

Materials:
• Cellulose Avicell (Sigma-Aldrich)
• BSA Protein
• Rocker
• Centrifuge
• Laemmli 2X
• Buffer A (50mM Tris, 150mM of NaCl)
• Heating table
• SDS-Page gel and cuve
• Protein ruler
• Microbiology equipment

Method:
1.Mix BSA with Buffer A to reach a concentration of 10mg/mL of BSA (10mg of BSA in 1mL of Buffer A)
2.In a 1.5mL eppendorf, put 1mL of protein solution (previously purified thanks to FPLC), 100 µL of BSA solution and 10mg of Avicell.
3.Let rocking 1h at room temperature
4.Centrifuge 2min at 13.000 rpm
5.Take 1mL of the supernatent and store it in a 2mL eppendorf
6.Resuspend the pellet in 1mL of Buffer A
7.Vortex and let rocking during 2min at RT
8.Centrifuge 2min at 13.000rpm
9.Collect the supernatent and pool it with the first taken
10.Resuspend the pellet in 800 µL of Laemmli 2X
11.Denaturate the protein by heating them at 95°C during 5min
12.Centrifuge 2min at 13.000rpm
13.Depose 20 µL of the supernatent
14.For the other samples: mix 10 µL of Laemmli 2X with 10 µL of protein (BSA alone, Prep2 after dialysis). Denaturate them 5min at 95°C
