Cultrex Mouse Laminin I, Pathclear Summary

Cultrex Mouse Laminin I, Pathclear is a purified basement membrane protein that has been developed and qualified as a extracellular matrix coating solution for cell attachment to tissue culture vessels.

Key Benefits

• Produced and qualified for use in cell culture
• Pathclear-tested to ensure a pathogen and virus-free material
• Source tissue is LDEV-free

Why Use Cultrex Mouse Laminin I?

Cultrex Mouse Laminin I, Pathclear is purified from Engelbreth-Holm-Swarm (EHS) tumor and is Pathclear-certified to be free of common pathogens. Laminin I is a major component of the basement membrane which is a continuous sheet of specialized extracellular matrix that forms an interface between endothelial, epithelial, muscle, or neuronal cells and their adjacent stroma and that plays an essential role in tissue organization by influencing cell adhesion, migration, proliferation, and differentiation.

  1. What is the recommended working concentration for Cultrex Laminin I?

    • The recommended working concentration for thin coating is 0.05-10 µg/cm2 . However, conditions must be optimized for each cell line or model. Cultrex Laminin I should be used at 6 mg/mL for 3-D culture applications.


  2. What is Laminin I?

    • Laminin I is a major component of extracellular matrix. Cultrex Laminin I is purified from murine EHS sarcoma. It is composed of α1β1γ1 chains with a total MW of 800,000 Da. Cultrex Laminin I increases cell adhesion, migration, growth, differentiation, neurite outgrowth, protease production, and malignancy. The response is dependent on cell type.

  3. Can Cultrex Mouse Laminin I be used on glass cover slips?

    • Coating glass cover slips with Cultrex Laminin I is quite common and has been published extensively.
