Tasks
- New protocol
- Vortex each 5 mL test tube of fibers until solution seems homogeneous
- Prepare concentrated buffer -> 50 mM Tris-HCl/20 mM CaCl2 pH 8 buffer.
- Prepare Proteinase K solution
- Add 0.927 mL of the homogeneous fiber sample from the vortexed 5 mL test tube + 0.020 mL of a 2.5 M Tris-HCl/0.5 M CaCl2 pH 8 buffer + 0.053 mL of protease for a total volume of 1 mL into an epitub.
- When the reaction is finished, spin the individual tube for 30 seconds and extract the supernatant for analysis
- Run Bradford of Proteinas K for 0, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 15, 20, 25, 30, 40, 50 ,60 min.
- 200μM of a 1 in 4 Bradford dilution (1 mL Bradford in 3 mL of Tris/NaCl buffer)
- 150μM of each proteinase K sample
- 550μM of tris/NaCl buffer
