Application

Laminin supports growth and differentiation of many cell types including epithelial, endothelial, neural, muscle and liver cells. It is recommended for use as a cell culture substratum at 1-2 μg/cm2. The optimal concentration does depend on cell type as well as the application or research objectives.

Biochem/physiol Actions

Laminin proteins are integral components of structural scaffolding in animal tissues. They associate with type IV collagen via entactin and perlecan and bind to cell membranes through integrin receptors, dystroglycan glycoprotein complexes and Lutheran blood group glycoproteins. Laminin has active domains for collagen binding, cell adhesion, heparin binding, and neurite outgrowth fragment.

Preparation Note

This product is supplied at a concentration of 0.5 mg/mL in 50 mM Tris-HCl, with 150 mM NaCl. It is 0.2 μm filtered. Thaw this solution slowly before use at 2-8°C to avoid gel formation. For use as a coating, dilute in a sterile balanced salt solution, coat culture surface with a minimal volume and incubate at 37°C for two hours. Wash 3 times with PBS before plating cells. Laminin coatings can be stored for one month at 2-8°C.

Other Notes

Laminin is an extracellular matrix multidomain trimeric glycoprotein, and is the main non-collagenous component of basal lamina that supports adhesion, proliferation and differentiation. Laminin is composed of both A, B1 and B2 chains, which are connected by many disulfide bonds. This laminin product is purified from human placenta using pepsin treatment and immunoaffinity chromatography. SDS-PAGE results in two major bands at 50 kDa and 130-160 kDa.

Disclaimer

It is recommended to store this product at -70°C, where it will remain stable for two years.

Questions

1–4 of 4 Questions  
  1. Is Product L6274, Laminin from human placenta, laminin 1 or 2?

    1 answer
    1. Fifteen laminin trimers have been identified. We do not determine what type of laminin this is. Typically laminin from placenta is considered laminin-2/4 and laminin from Engelbreth-Holm-Swarm murine sarcoma basement membrane is laminin-1.

  2. How do you prepare Product L6274, Laminin from human placenta?

    1 answer
    1. To prepare a laminin solution, we recommend that the L6274 be thawed at 2-8°C to avoid the formation of a gel. This can be further diluted in a balanced salt solution. If the product has been thawed at room temperature and ends up as a gel, it cannot be reactivated for use.

    Functional protein for culture use

    I use this in a plate coating buffer for primary cell culture. While the protocol called for laminin from another manufacturer (backordered), I tried this one with great success. This protein is functional and supports epithelial cell growth.
