iMatrix 332
Maintenance and purification of corneal epithelial cells and keratinocytes.
Product Basics
iMatrix-332 is a recombinant human Laminin 332-E8 fragments protein expressed by CHO-S cell. Laminin 332 is composed of α3β2γ2 chain, which is known to bind to integrin α3β1 and α6β4. It is essential for cells in the epithelial basement membranes, lining the surfaces of the body such as the skin, hair follicles, oral cavity, gastrointestinal and urinary tracts, lungs, and different glands.
Key Features
- Highly purified and refined human laminin-332 E8 fragment expressed by CHO-S cell
- iMatrix-332 can be used to support directed differentiation for corneal epithelial cells and keratinocytes
- Feeder-free cell culture
Applications
iMatrix-332 can be used as cell culture matrix for various cell types including ES/iPS cells.
Procedure
- Dilute the solution with sterile PBS (-). Coat dishes with 0.5 ug/cm². Add 2 mL of diluted iMatrix-332 solution to the well. The optimal coating concentration depends on cell lines from 0.1 to 1.5 ug/cm². (For example, when you use 6-well plate (9.6 cm²/well), add 9.6 ul of iMatrix-332 (4.8 ug) in 1.99 ml of PBS(-).)
- Incubate for 1 hour at 37 °C, 3 hours at room temperature, or over-night at 4 °C.
- Remove remaining fluid from the coated surface. No rinse is needed.
- Immediately plate the cells at desired density.
Notes: Don’t allow the plate to dry. Briefly spin down all liquid in the tube before use. Avoid repeated freeze-thaw cycles.
