FACS analysis for cell cycle and apoptosis was done 72 hours post-transfection. The cells were harvested, washed with cold PBS, and resuspended in the nuclear stain DAPI for cell cycle analysis or stained with 7-AAD and Annexin-V-FITC using ANNEXIN V-FITC/7-AAD KIT (BD Biosciences) for apoptosis analysis according to the manufacturer’s protocol. Stained cells were immediately analyzed by FACS (BD FACSVerse; BD Biosciences). Cell viability was determined at 24, 48 and 72 h by using the CellTiter 96 AQueous One Solution Cell Proliferation Assay kit (Promega, Madison, WI) according to the manufacturer’s protocol. Also a cytoselect 24-well cell migration and invasion assay kit (Cell Biolabs, Inc) was used for migration and invasion assays according to the manufacturer’s protocol. For migration and invasion assays two replicates were used and the experiment was repeated three times.

Cell migration and invasion were assessed by using CytoSelect 24-well Cell Migration and Invasion Assay kit (cat no. CBA-100-C, Cell Biolabs), according to the manual. In brief, 1.5 × 105 cells in 300 μl of RPMI were placed on an 8-μm pore size polycarbonate membrane insert (for migration) or on a polycarbonate membrane insert coated with a basement membrane layer (invasion assay) in 500 μl of 10% RPMI. After incubation for 24 h (migration) or 48 h (invasion assay), non-migratory cells in the upper chamber were carefully removed with cotton-tipped swabs, and the migratory cells were stained and read by a plate reader (Versamax tunable microplate reader, Molecular devices) at an optical density of 560 nm.

Cell migration and invasion were assayed using a CytoSelect™ 24-Well Cell Migration and Invasion Assay kit (Cell Biolabs, Inc., San Diego, CA) according to the manufacturer’s protocol. In brief, SKOV3 cells were treated with either control or STIP1 siRNA for 48 h, and were subsequently suspended in serum free medium (1.0 × 106 cells/mL). Cell suspension (300 μL) was added to the upper chamber. The membrane chambers were then transferred to the lower well of the migration plate, which was filled with 10% fetal bovine serum-containing media. Cells were allowed to migrate for 24 h at 37°C. Migratory cells that had passed through membrane were collected, lysed, and quantified at OD 560 nm using a plate reader.
For invasion assays, cells were treated with either control or STIP1 siRNA for 48 h, and were subsequently suspended in serum free medium (1.0 × 106 cells/mL). Cell suspension (300 μL) was added to the upper chamber, which was coated with a uniform layer of dried basement membrane matrix solution. The membrane chambers were then transferred to the lower well of the invasion plate, which was filled with 10% fetal bovine serum-containing media. Cells were allowed to invade for 24 h at 37°C. Invasive cells that had passed through the basement membrane layer were collected, lysed, and quantified at OD 560 nm using a plate reader.

FACS analysis for cell cycle and apoptosis was done 72 hours (96 hrs for MDAPCab cells) post-transfection using nuclear stain DAPI for cell cycle analysis or ANNEXIN V-FITC /PI KIT (Betkin Dikeson) for apoptosis analysis according to the manufacturer's protocol. Cell viability was determined at 24, 48, 72 and 96 h by using the CellTiter 96 AQueous One Solution Cell Proliferation Assay kit (Promega, Madison, WI) according to the manufacturer's protocol. For colony formation assay, cells were seeded at low density (1000 cells/plate) and allowed to grow until visible colonies appeared. Then, cells were stained with Giemsa and colonies were counted. Cytoselect 24-well cell migration and invasion assay kit (Cell Biolabs, Inc) was used for migration and invasion assays according to manufacturer's protocol.

Migration and invasion of BC cells were assessed using CytoSelect 24-well Cell Migration and Invasion Assay kit (CBA-100-C, Cell Biolabs) following manufacturer instructions [27 (link),28 (link)]. In brief, 1.5 × 105 cells placed on an 8-μM pore size insert. After incubation for 24 h or 48 h, the non-migratory/non-invasive cells the upper chamber were carefully removed with cotton-tipped swabs, and the migratory/invasive cells processed per vendor’s protocol and read by a plate reader (Versamax tunable microplate reader, Molecular Devices) at λ560 nm. Before removing the cells from the upper chamber, the non-migratory cells visualized by a Nikon ECLIPSE TE200-U microscope (Nikon Instruments Inc., Melville, NY, USA). Digital images were captured using Nikon NIS Elements software (Nikon Instruments Inc., Melville, NY, USA).

The migration and invasion assay was performed using the CytoSelect 24-Well Cell Migration and Invasion Assay kit (8 μm, Colorimetric Format, Cell Biolabs, San Diego, CA), according to the manufacturer's instructions. Briefly, the migration assay plate was incubated at room temperature for 10 min, and an invasion basement membrane layer of the cell culture insert was rehydrated with warm serum-free RPMI 1640 media for 1 h at room temperature. Cells were detached from the culture plate by trypsinization and resuspended in serum-free RPMI 1640 media. RPMI 1640 media containing 10% FBS was added into the lower chamber, and the cell suspensions were applied to the upper chamber of the migration/invasion insert. Chambers were incubated at 37°C for 24 h and the membrane was stained with cell stain solution at room temperature. The stained migratory or invasive cells were analyzed by a Nikon ECLIPS TS100 inverted microscope (Nikon Instruments).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
