Ganglioside GQ1b (bovine) (ammonium salt)

Ganglioside GQ1b is a tetrasialoganglioside that contains two sialic acid residues linked to an inner galactose unit. It stimulates phosphorylation of several ecto-type protein kinase substrates on the surface of GOTO human neuroblastoma cells when used at a concentration of 5 nM. Ganglioside GQ1b promotes differentiation of murine embryonic stem cells (mESCs) to neuronal precursor and glial cells via activation of the ERK1/2 pathway. It also induces differentiation of murine keratinocytes through phosphoinositide turnover. This product contains ganglioside GQ1b molecular species with primarily C18:0 fatty acyl chain lengths. As this product is derived from a natural source, there may be variations in the sphingoid backbone. [Matreya, LLC. Catalog No. 1516]Formal Name: ganglioside GQ1b, tetraammonium salt.
