Method

Stimulation hTERT cells

  • Remove medium form 24-wells plate with ASMC's grown ON in DMEM (S0)
  • Rinse twice with warm PBS and remove buffer
  • Add 300 μL DMEM S0 with HT31P 0 - 50 μM (see schedule below)
    • Incubate 20 min.
    • Prepare 25 mL DMEM S0 with 100% CSE
    • Dilute 100% CSE to 30% CSE (3 mL CSE 100% + 7 mL S0)
  • Add 300 μL 30% CSE to wells according to schedule below (lane C & D)
  • Incubate 24 h.

  • Wash of BSA with 200 μL Washing buffer 5x
  • Add 100 μL of diluted sample
  • Incubate ≥1h @ RT
  • Wash 5x 200 μL Washing buffer
  • Remove buffer
    • prepare biotinylated antibody
  • Add 100 μL Biotinylated antibody
  • Incubate 1h @ RT
  • Remove antibody
  • Wash 5x 200 μL Washing buffer
  • Add 100 μL streptavidin conjugated to HRP
  • Incubate 25 min. @ RT
  • Remove liquid
  • Wash 5x 200 μL Washing buffer
    • prepare TBM substrate
    • 1.2 μL H2O
    • 400 μL TBM stock solution
    • 24 mL substrate buffer
  • Add 100 μL substrate
  • Incubate 30 min. @ RT
  • Stop reaction, add 100 μL stopping solution
    • It will turn yellow
  • Measure absorbance @ 450 nm
    • Check duplo standard curve
    • Check if values fall within standard curve (preferred)
