Title: Frn kossor till jordgubbar


1
Från kossor till jordgubbar
2
Sorting strawberries on size
3
Jordgubbssortering
  • Protoplaster
  • Art A Art B
  • Lyckad fusion SORTERAD
  • Kan göras för t.ex
  • potatis
  • andra växtceller
  • STORA celler 20-50 mm

4
Nozzleregel
  • Nozzle minst 3 x partikel
  • Stor partikel stor nozzle låg frekvens låg
    hastighet
  • Liten partikel liten nozzle hög frekvens
    hög hastighet

5
Celltyper
  • Lymphocytes
  • Monocytes, macrophages
  • Stem cells
  • Dendritic cells
  • Tumor cells
  • Bacteria
  • Marine organisms
  • Yeast
  • Drosophila
  • Mitochondria
  • Beads

High speed sorting applications
höghastighetssorteringsapplikationer
  • Rare events
  • Stem cell selection (lt0.5)
  • Dendritic cells
  • Transfected populations
  • Multimers (T cells)
  • Large volume
  • X/Y sperm selection

Stem cells -SP
13
Exempel the case for high speed sorting
  • 0.1 pos cells
  • Behöver 106 cells
  • Hastighet
  • 5 keps
  • 10 keps
  • 50 keps
  • Hur lång tid tar det?
