Notes before starting and general advice on material handling
- All handling of the P3D Scaffolds products should be performed using gloves, according to the standard aseptic methods.
- The scaffolds are supplied sterile by dry heat sterilization and remains sterile until opened.
Procedure
- Aspirate cell medium.
- Wash 10-20x in prewarmed PBS for 1 minute each wash. It is important to remove all trace of medium.
- Cover scaffolds in lysis buffer.
- Shake scaffolds at 300 rpms for 30 min.
- Flush scaffolds and collect lysate in Eppendorf tubes.
- Centrifuge samples at 16,000 g for 20 min at 4C.
- Place samples on ice and pipette supernatant with proteins in to clean prelabelled Eppendorf tubes.
- Samples can now be stored at -80C and continue to downstream protein applications.
