Figure 4: Invasion chamber assay for siRNA-transfected OVCA 429 cells. NGAL siRNA-treated cells and mock transfected cells were put into modified Boyden chambers to determine the ability of treated cells to invade a synthetic membrane. The total number of invading cells were counted after 24 h (72 h post transfection) and the mean calculated. No significant difference was detected between NGAL siRNA-treated cells and mock transfected cells.
