Recombinant Laminin-221 E-8 Fragments

iMatrix-221's features make it an ideal matrix for some cell culture applications:

  • Xeno-free formulation / CHO-S cell bioproduction
  • Easy to use (liquid format)
  • E8-fragments retain integrin binding specificity and capacity, and display higher potency than natural Laminin-221

iMatrix-221 is a highly purified and refined product of human recombinant laminin-221 (E8 fragment) expressed by CHO-S cells. Laminin-221 is found predominantly in the basal lamina of striated muscle tissues. Expression deficiencies are implicated in muscular dystophy and cardiomyopathies.1

Laminins of the α-2 type are also a predomiant form found in the human adult heart tissue.2 Cultivation of iPSC-drived cardiomyocytes on iMatrix-221 has been demonstrated to maintain strong contractility in attached monolayer culture.3
