SLC41A1 Knockout Cell Line (HCT 116)

The choice depends on whether you are studying SLC41A1's role as a Mg²⁺ efflux transporter or its emerging functions in magnesium homeostasis and disease contexts (Parkinson's disease genetic association, preeclampsia). The Knockout line is the standard tool for asking whether SLC41A1 is required for cellular magnesium extrusion — SLC41A1 functions as a Na⁺/Mg²⁺ exchanger at the plasma membrane. Overexpression is useful for testing transport activity in heterologous systems or for studying SLC41A1 in cancer contexts where altered magnesium homeostasis affects proliferation. For magnesium biology research, the EDITGENE SLC41A1 Knockout in HCT 116 enables study of cellular magnesium efflux and downstream Mg²⁺-dependent processes. Rescue with wild-type or transport-deficient SLC41A1 is the standard specificity control. Combined analysis with TRPM7 (the major Mg²⁺ uptake channel) and SLC41A2 paralog expression provides comprehensive Mg²⁺ homeostasis characterization.

Primary applications: • Magnesium efflux assays: Mag-Fluo-4 imaging or ICP-MS-based intracellular Mg²⁺ measurement to quantify SLC41A1 efflux activity. • Sodium-coupled transport: assessment of Na⁺-dependence of Mg²⁺ extrusion to characterize the Na⁺/Mg²⁺ exchange stoichiometry. • Parkinson's disease genetic studies: rescue with disease-associated SLC41A1 variants given reported genetic associations with PD risk. • Cellular Mg²⁺ homeostasis: combined analysis with TRPM7 and SLC41A2 expression to characterize Mg²⁺ network. EDITGENE recommends this model for researchers investigating cellular magnesium efflux biology and Mg²⁺-related disease mechanisms.

Yes. SLC41A1 rescue experiments require attention to Mg²⁺ efflux mechanism: • Construct design: use a codon-modified SLC41A1 sequence with a small C-terminal tag (FLAG, HA). SLC41A1 has 10 transmembrane domains — N-terminal tags must not disrupt topology. • Transport-deficient rescue: conserved residue mutations in the MgtE-related membrane domain enable structure-function studies. • Surface localization validation: SLC41A1 trafficks to the plasma membrane — confirm exogenous surface localization by cell surface biotinylation before functional assays. • Functional readout: rescue should restore cellular Mg²⁺ efflux measured by Mag-Fluo-4 imaging or ICP-MS. HCT 116 transduces efficiently with lentivirus and supports stable rescue line generation.
