Biolaminin 121 LN (LN121)

Human recombinant laminin 121

Biolaminin 121 is a full-length and animal-origin free human laminin 121 protein, that can be used as a general attachment protein for most cell types in vitro.

A defined culture substrate for many cell types

Laminins 111 and 121 are widely expressed during embryogenesis and are important for early epithelial development and differentiation of the epiblast. Laminins induce different cell signaling cascades and co-signal with various growth factors in a cell-type-dependent manner. Biolaminin 121 LN (LN121-02 and LN121-0501) can support the survival, proliferation, and differentiation of many different cell types in vitro.

Improved neurite outgrowth and postsynaptic myotubes

Laminin 121 has a higher affinity to integrin receptors compared to laminin-111, especially to integrins α7β1 and α6β1 (Sasaki, 2010). Laminin 121 has been shown to be especially supportive to neurite outgrowth (Sasaki, 2010). Human myotubes cultured on a combination of Biolaminin-121 and -221 were also shown to have the most developed clusters of postsynaptic machinery (Pęziński, 2020).
