Mouse COL18A1 Recombinant Protein (C-Fc) is a recombinant protein expressed in mammalian cells, spanning His1591-Lys1774, with a C-terminal Fc tag. Predicted molecular weight: 48.71 kDa. Purity: >90% as determined by SDS-PAGE. Supplied lyophilized from a solution in PBS pH 7.4, 1 mM EDTA, 4% Trehalose, 1% Mannitol. Applications: ELISA, immunogen, SDS-PAGE and Western blot. Collagen alpha-1(XVIII) chain is a ~182 kDa protein. Probably plays a major role in determining the retinal structure as well as in the closure of the neural tube. For research use only.
