- 实验流程
- The CytoSelect™ Collagen Cell Invasion Assay Kit contains polycarbonate membrane inserts (8 μm pore size) in a 24-well plate. The upper surface of the insert membrane is coated with a uniform layer of dried Bovine Type I Collagen matrix. This collagen matrix layer serves as a barrier to discriminate invasive cells from non-invasive cells. Invasive cells are able to degrade the collagen matrix layer, and ultimately pass through the pores of the polycarbonate membrane. Finally, the cells are removed from the top of the membrane and the invaded cells are stained and quantified.
- 实验流程
-
- Under sterile conditions, allow the collagen invasion chamber plate to warm up at room temperature for 10 minutes.
- Rehydrate the collagen layer of the cell culture inserts by adding 300 μL of warm, serum-free media to the inner compartment. Incubate at room temperature for 30 minutes.
- Prepare a cell suspension containing 0.5-1.0 x 106 cells/mL in serum free media. Agents that inhibit or stimulate cell invasion can be added directly to the cell suspension. Note: Overnight starvation may be performed prior to running the assay.
- Carefully remove 250 μL of rehydration medium (step 2) from the inserts without disturbing the collagen layer (leaving 50 μL inside).
- Add 250 μL of the cell suspension solution to the inside of each insert.
- Add 500 μL of media containing 10 % fetal bovine serum or desired chemoattractant(s) to the lower well of the invasion plate.
- Incubate for 12-24 hours in a cell culture incubator.
- Carefully aspirate the media from the inside of the insert. Wet the ends of 2-3 cotton-tipped swabs with water, flatten the ends of the swabs by pressing them against a clean hard surface, and gently swab the interior of the inserts to remove non-invasive cells. Take care not to puncture the polycarbonate membrane. Be sure to remove cells on the inside perimeter of the insert.
- Transfer the insert to a clean well containing 400 μL of Cell Stain Solution and incubate for 10 minutes at room temperature.
- Gently wash the stained inserts several times in a beaker of water. Allow the inserts to air dry.
- (optional) Count invasive cells with a light microscope under high magnification objective, with at least three individual fields per insert.
- Transfer each insert to an empty well, adding 200 μL of Extraction Solution per well, then incubating 10 minutes on an orbital shaker.
- Transfer 100 μL from each sample to a 96-well microtiter plate and measure the OD 560nm in a plate reader. 4

- 背景
- The ability of malignant tumor cells to invade normal surrounding tissue contributes in large part to the significant morbidity and mortality of cancers. Invasiveness requires several distinct cellular functions including adhesion, motility, detachment, and extracellular matrix proteolysis. Metastatic cells produce many proteolytic enzymes (e.g. lysosomal hydrolysates, collagenases, plasminogen activators) while the expression of certain cell surface protease receptors is also increased.
