Materials

Stimulation

ELISA

  • Supernatants collected 5March2010 (D12), 10March2010 (D12, P25) & 11March2010 (D9, P21)
  • PBS 5%
  • BSA 5% in PBS (20 mL per 96-wells)
  • Pelikine Compact™ Human IL-8 ELISA kit
  • Washing buffer (PBS + 0.005% TWEEN 20)
  • IL-8 antibody
  • Streptavidin conjugated to HRP
  • Substrate buffer
    • 1.5 sodiumacetate, resuspend in 80 mL ultrapure water
    • pH 5.5
    • up to 100 mL with ultrapure water
  • TMB stock solution (light sensitive)
  • Dilution buffer (1:5, 32 mL H2O, 8 mL undiluted buffer)

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.

ELISA

Preparing Sandwich

  • Wash coated plate 5x 200 μL PBS
  • Remove PBS
  • Add 200 μL BSA
  • Incubate 1h @ RT and remove BSA
    • Dilute samples as shown below for each 24-wells (dilution buffer (μL)/sample (μL))

  • 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)
