Introduction
Cell adhesion plays an important role in cellular communication ａnd regulation, ａnd is of fundamental importance in the development ａnd maintenance of tissues. Collagen I, a major structural component of extracellular matrices, is an excellent substrate for the culture of many different cell types. The ScienCell™ Collagen I Cell Adhesion Assay is designed for the rapid, quantitative ａnd reliable measurement of cell adhesion to collagen I. The kit includes a 48-well plate pre-coated with collagen I, as well as BSA （bovine serum albumin） as negative controls （see plate format in Figure 1）. Cells are cultured in the pre-coated wells for a desired period of time, then unbound cells are washed away, ａnd the adhered cells are fixed ａnd stained, followed by an extraction step which leads to dye elution from stained cells into supernatant. Thus cell adhesion can be quantified using a colorimetric ELISA plate reader at 595 nm.
Kit components
| Cat. No. | Item / Vial | Name | Quantity | Storage |
| 8008a | 1 | Collagen I & BSA coated plate | 48-well | 4°C |
| 8008b | 1 | Staining solution | 10 ml | 4°C |
| 8008c | 1 | Extraction soulution | 10 ml | 4°C |
Quality Control
Serial diluted Human Pulmonary Fibroblasts （Cat. No. 3300, ScienCell™） are cultured in the pre-coated 48-well plate. A linear relationship can be observed between signals produced （OD590nm） ａnd the number of cells, as shown in Figure 2.
Procedure
1. Under sterile conditions, allow the pre-coated 48-well plate to warm to room temperature ａnd rinse once with PBS.
2. Seed cells of interest into the 48-well plate ａnd culture for a desired period of time （at least 30-90 minutes） at 37°C.
3. After the culture is done, remove culture medium ａnd rinse cells with PBS for 3-5 times.
4. Add 200 µl/well of freshly diluted 0.1% glutaraldehyde in PBS, fix for 10 minutes at room temperature. Then discard fixing solution ａnd rinse cells 3 times with PBS.
5. Add 200 µl/well of Staining Solution; incubate for 30 minutes at room temperature on an orbital shaker.
6. After the staining is done, rinse plate with DI water 3-5 times, invert plate onto paper tower to drain water residue ａnd leave the plate in air for dry.
7. Add 200 µl/well of Extraction Solution, incubate for 3-5 minutes ａnd read OD595nm using an ELISA plate reader.
