SLC5A6 Knockout Cell Line (HEK293)

The choice depends on whether you are studying SLC5A6 (SMVT)'s role as a sodium-dependent multivitamin transporter or its essential functions in biotin, pantothenate, and lipoate uptake. The Knockout line is appropriate for asking whether SMVT is required for these vitamin transport activities — SMVT is the principal transporter for these substrates in most tissues. Overexpression is useful for transport kinetics studies and for examining substrate specificity. For SMVT research, the EDITGENE Knockout in HEK293 is a standard mechanistic platform for vitamin transport biology — HEK293 has well-characterized transfection-based experimental capabilities. This product complements the parallel SLC5A6 Knockout in HCT 116 (also available). SMVT mutations cause biotin-thiamine-responsive basal ganglia disease in some clinical contexts. Rescue with wild-type or transport-deficient SMVT enables structure-function studies, and is critical as a specificity control for SMVT-mediated drug-vitamin conjugate delivery research.

Primary applications: • Vitamin uptake assays: ³H-biotin, ³H-pantothenate, or ³H-lipoate uptake to quantify SMVT activity in the absence of SLC5A6. • Multivitamin transport kinetics: competition assays among biotin, pantothenate, and lipoate to characterize SMVT substrate handling. • Drug-vitamin conjugate research: testing biotin-conjugate uptake for targeted drug delivery strategies. • Heterologous expression structure-function: HEK293 supports high-quality biochemical characterization of SMVT variants. EDITGENE recommends this HEK293-based model for biochemical and mechanistic SMVT research; the parallel SLC5A6 Knockout in HCT 116 is preferred for intestinal absorption contexts.

Yes. SMVT rescue experiments are well-established for multivitamin transport research: • Construct design: use a codon-modified SLC5A6 sequence with a small C-terminal tag (FLAG, HA). SMVT has 13 transmembrane domains — N-terminal tags must not disrupt membrane insertion. • Transport-deficient rescue: sodium-binding or substrate-binding pocket mutations enable structure-function studies. • Vitamin-conjugate studies: rescue enables direct comparison of SMVT-mediated uptake of native vitamins versus biotinylated drug conjugates. • Functional readout: rescue should restore ³H-biotin, ³H-pantothenate, and ³H-lipoate uptake activities. HEK293 transduces efficiently with lentivirus and is the standard heterologous expression background for SMVT biochemistry.
