The machining and wear performance of TiN-coated and patterned carbide inserts incorporating indium as a solid lubricant are reported in this study.
Cell culture inserts incorporating polyethylene terephthalate membranes (6.4-mm diameter, 8- μm pore size) and 24-well plates for invasion assays were purchased from Costar (Cambridge, MA, USA).
The murine immunizations showed that despite the relatively small size of the expressed recombinant insert, like other haptens SIVsm derived inserts incorporated into the GvpC "carrier" protein on gas vesicles surfaces, are clearly visible and can initiate immune responses.
Cell migration was measured in chemotaxis 24-transwell plates using collagen-I-coated inserts incorporating polyethylene terephthalate track-etched membranes with 8- μm pores (Becton Dickinson Biosciences, Le Pont De Claix, France).
We also speculate that we might have observed different results with this assay if we had used monoclonal antibody, targeted to the hexon region where the insert was incorporated.
Cells were detached with trypsin and 5 × 104 [H]-labeled cells in 100 μl medium were added to each well in a 24-transwell permeable plate (8.0 μm polycarbonate membrane, 6.5 mm insert; Corning Incorporated, Corning, NY, USA) coated with Matrigel basement membrane matrix (1 60 dilution; BD Biosciences, San Jose, CA, USA).
The basal cells were trypsinized and seeded at a density of 6×105 cells/cm2 onto a 0.4 µm pore-sized Costar Transwells inserts (Corning Incorporated, Corning, NY) pre-coated with type IV collagen (Sigma, St Louis, MO).
Cells were plated in Transwell® inserts (Corning Incorporated, Corning, NY, USA) at a density of 100.000/cm in serum-containing medium and cultured overnight.
Effect of CPP ecp on cell migration was assessed using a 24-well transwell plate inserted with incorporating polyethylene terephthalate filter membrane with 8 μm pores (BD FalconTM Cell Culture Insert System).
Basal cells were then expanded into 75-cm flasks and upon confluence seeded at 10 cells/cm on 1.2-cm-diameter transwell clear inserts (Corning Incorporated) under BEGM for 2 days.
