Product Description


Laminin 511 is known to bind to Intergin α6β1 of the cell surface.

iMatrix-511 is highly purified human Laminin 511-E8 fragments recombinantly expressed by CHO-S cell.

Product Size : 1050ug  (175ug x 6 pcs.)


iMatrix-511 can be used as cell culture matrix for various cell types including ES/iPS cells.


Liquid Solution (175ug/vial @0.5mg/mL Solvent: PBS(-)) .

**Specification **
Format: Solution (175ug/vial @0.5mg/mL)
Storage temperature: 2-15°C
NaCl concentration: 137mM


The dissociation constant of the binding activity with integrin α6β1 is under 10nM.



1. Dilute the solution with PBS (-). Coat dishes with 0.5ug/cm².

* The optimum coating concentration depends on cell lines from 0.1 to 1.5ug/cm².

** For example, when you use 6-well plate (9.6 cm²/well), add 9.6ul iMatrix-511 (4.8ug) in 1.99ml of PBS(-). Add 2mL of diluted iMatrix-511 solution to the well.

2. Incubate for 1 hour at 37C, 3 hours at Room temperature, or over night at 4C.

3. Remove excess fluid from the coated surface. No rinse is needed.

4. Immediately plate the cells at desired density.

*** Don't allow the plate to dry.

**** Briefly spin down all liquid in the tube before use.

***** Avoid repeated freeze-thaw cycles.

****When culturing ES/iPS cell, Feeder Free and Single cell subculture can be done using iMatrix-511.*****
