MEF-1

Study of LRP and LRP-deficiency

Mouse embryo fibroblast, SV40 - transformed

The cell line MEF-1 was established by transfection of mouse embryo fibroblasts ((C57 BL/6 x 129) F1) with a SV40 coding plasmid. MEF-1 express the wild-type for low density lipoprotein receptor related protein (LRP). Together with the cell lines PEA10 (Sigma Catalogue number. 97040310) and PEA13 (Sigma Catalogue number. 97040311), which express heterozygous and homozygous forms of LPR, an experimental system is available for the analysis of cellular uptake of functionally diverse ligands and the effect of LPR - deficiency. This is of importance since LRP - deficient mouse embryos die early during gestation.
