Methods

Type III secretion system RK13 cell Injection Assay

Seed RK13 cells

  1. Remove the culture medium and wash 3 times PBS followed by trypsinization
  2. Suspend RK13 cells with antibiotics free RPMI-10% FCS
  3. Seed 6 x 105/well RK13 on the 6 well plate coated with poly-L-Lysin 24 hrs before infection

Prepare E. coli culture

  1. Grow E. coli K12 (SPI2/Signal-GFP), E. coli K12 (SPI2) and E. coli K12 (Signal-GFP) in 4 mL of LB (+0.4% Arabinose) with appropriate antibiotics at 37C overnight

5 hrs before injection

  1. Centrifuge 4 mL of E. coli culture at 3,500 rpm for 10 min in the round tube
  2. Discard the supernatant and resuspend with 4 mL of MgM-MES(pH 5.0) + 0.4% Arabinose with appropriate antibiotics and grow at 37C for 4 hrs
  3. 4 hrs later centrifuge the culture 3,500 rpm for 10 min and discard the sup
  4. Resuspend the pellet with 2 mL of antibiotics free RPMI-10% FCS and transfer the culture into micro tube
  5. Centrifuge the culture 6,000 rpm for 3 min and discard the sup
  6. Repeat step 4 and 5 three times
  7. Measure and adjust the concentration of E. coli RPMI culture (ΔOD = 0.5)

Injection

  1. Remove the RPMI on RK13
  2. Add 900 uL of fresh RPMI-10% FCS and then 100 uL of E. coli RPMI culture (ΔOD = 0.5)
  3. Incubate the plate at 37C for 1 hrs, 5% CO2 with or without shaking
  4. Wash the wells with penisilin/ strepromicin containing RPMI-10% FCS twice
  5. Add 2 mL of penisilin/ streptomicin containing RPMI-10% FCS/well
  6. Incubate the plate at 37C for 1 hr, 5% CO2
  7. Observe the cells by fluorescence microscope under blue light at every 30 min
