Intended useThe Innocyte™ Cell Adhesion Microplate Assays are designed for the determination of the relative attachment of adherent cell lines to extracellular matrix proteins such as Human Fibronectin (Cat. No. CBA011), Human Vitronectin (Cat. No. CBA012), and Human Collagen IV (Cat. No. CBA013). Cells are seeded onto a coated substrate, which is followed by the determination of relative cell attachment using a fluorescent dye.
BackgroundThe extracellular matrix (ECM) provides vital structure and organization to most organisms. It is an assemblage of collagens, proteoglycans, and glycoprotein such as fibronectin and vitronectin. The ECM undergoes a constant remodeling that is most obvious during development, wound healing, and other repair processes. Fibronectin is a prominent constituent of the ECM around many cells, and fibronectin-rich matrices provide substrates for cell adhesion and migration during development, wound healing, and other processes, and affect many cellular functions, including proliferation, survival, and differentiation. Vitronectin is a member of the pexin family. It is found in serum and tissues and promotes cell adhesion and spreading, inhibits the membrane-damaging effect of the terminal cytolytic complement pathway, and binds to several serpin serine protease inhibitors. Collagen type IV is a prominent component of the basement membrane. Collagen IV can stimulate tumor cell proliferation, migration, and adhesion in a dose-dependent manner. Powerful cytokines such as TGF-β1 play an important role in stimulating the expression of collagen IV. Adhesive receptors on the cell surface such as integrins, selectins, cadherins, and ICAMs interact in a specific manner with different ECM proteins. Adhesion molecules reside in complex structures like focal adhesion adhesions and synaptic and adherens junctions, which also contain many specialized cytoskeletal proteins and signaling molecules.
Principles of the assayThe Innocyte™ Cell Adhesion Assay is designed for the analysis of cell attachment to ECM proteins. After incubation followed by a brief wash step, attached cells are quantified with the green fluorescent dye calcein-AM. BSA-coated wells serve as a negative control, and poly-L-lysine-coated wells serve as a positive control for general attachment.
Materials provided• Fibronectin-Coated Plate (Kit Component No. JA7840-1EA): 1 black 96-well plate supplied as six 16-well strips; Rows 2-7 are coated with fibronectin, row 1 is coated with BSA, and row 8 is coated with poly-L-lysine

Table 1: Assay Template


• Calcein-AM Solution (Kit Component No. JA7705-50UL): 1 vial, 50 µl
• D-PBS (Kit Component No. JA7706-10ML): 1 vial, 10 ml
Materials Required but not provided• Pipettors with disposable tips
• Fluorescence reader capable of measuring fluorescence in 96-well plates with a filter set of approximately excitation wavelength 485 nm and emission wavelength 520 nm
• PBS, preferably containing calcium/magnesium (Dulbecco's PBS) for washing
Reagent preparation• Calcein-AM Working Solution: Warm the calcein-AM solution and the D-PBS to room temperature. Dilute the calcein-AM stock solution 1:300 with D-PBS, i.e. add 20 µl (calcein-AM solution) to 6 ml of D-PBS. This calcein-AM working solution cannot be stored.
Detailed protocol1. Harvest cells and resuspend the cell pellet in serum-free media. Cell density should be between 100,000 and 500,000 cells/ml.
2. Add 100 µl of the prepared cells suspension, in duplicate, to the wells and incubate for 1-2 h at 37°C in a cell culture incubator.
3. Discard the cell suspension and gently wash wells twice with 200 µl of PBS.
4. Add 100 µl of the calcein-AM working solution to each well.
5. Incubate for 1 h at 37°C in a cell culture incubator.
6. Measure the fluorescence of the samples using a fluorescence plate reader at excitation wavelength ~485 nm and emission wavelength ~520 nm.
Assay characteristics and examples

Figure 1: Example Data

~25,000 cells were added to each well and allowed to attach for 1.5 h at 37°C in 6% CO2. Cells were washed gently with D-PBS and labeled with calcein-AM for 1 h at 37°C in 6% CO2. The relative attachment of cells to poly-L-lysine was determined for HUVECS only and was lower than that of the displayed ECM proteins (data not shown).
