Cutting-edge product for stem cell research and human embryo modelling

Amsbio reports that its iMatrix-511 recombinant laminin product has been cited in a recent paper** from researchers at the Stanford University School of Medicine, Stanford, CA, USA as a pivotal tool for stem cell culture and blastoid formation.

This groundbreaking study describes how human blastoid models (stem-cell derived blastocyst-like structures) were used to investigate how human-specific LTR5Hs elements regulate early embryonic development. It provides new unique insights into epiblast differentiation and early embryogenesis.

iMatrix 511 is a highly purified and refined version of the human recombinant laminin-511 E8 fragment expressed by CHO-S cells. Widely regarded as a gold standard for stem cell culture, iMatrix-511 is an innovative cell culture matrix which permits ES/iPS cells to be maintained in feeder-free culture conditions. Immediately available from stock– iMatrix-511 also enables the passaging of single cells and is proven to provide greater adhesion than full-length Laminin, Vitronectin or Matrigel.

iMatrix-511 can also be used together with Amsbio’s StemFit cell culture media and CELLBANKER cryopreservation series as part of an expanded Stem Cell Synergy solution for ES/iPS cell cultures.
