SLC35A5 Knockout Cell Line (HEK293)

The choice depends on the experimental question. SLC35A5 belongs to the SLC35 nucleotide sugar transporter family, but its substrate specificity and cellular function are less well characterized than SLC35A1-A4. The Knockout line is most useful for discovery-oriented studies to identify cellular processes requiring SLC35A5 — given the family's role in delivering nucleotide sugars (UDP-GlcNAc, GDP-fucose, etc.) for glycoprotein and glycolipid biosynthesis. Overexpression is useful for substrate identification through reconstituted transport assays. For SLC35 family research, the EDITGENE SLC35A5 Knockout in HEK293 provides a clean background for characterizing this transporter's substrate scope. Glycomic profiling and lectin staining in the knockout can identify candidate substrate classes. Rescue with wild-type SLC35A5 enables initial functional characterization.

Primary applications: • Substrate discovery: in vitro Golgi transport assays with a panel of nucleotide sugars (UDP-GlcNAc, UDP-GalNAc, UDP-Glc, UDP-Gal, GDP-Man, GDP-Fuc, CMP-NeuAc) to identify SLC35A5 substrate specificity. • Glycomic profiling: cellular glycan composition analysis by MALDI-TOF mass spectrometry to identify glycosylation changes associated with SLC35A5 loss. • Lectin staining: surface lectin binding profile changes to characterize candidate substrate-dependent glycan structures. • Subcellular localization: imaging of epitope-tagged rescue constructs to characterize Golgi targeting. EDITGENE recommends this model for researchers investigating SLC35 family nucleotide sugar transporter biology and Golgi glycosylation mechanisms.

Yes, and rescue experiments are particularly important for substrate discovery: • Construct design: use a codon-modified SLC35A5 sequence with a small C-terminal tag (FLAG, HA). The 10 transmembrane SLC35 family architecture should be preserved. • Discovery-oriented rescue: parallel rescue with wild-type construct during glycomic profiling distinguishes true SLC35A5-dependent glycan changes from off-target editing artifacts. • Localization validation: confirm Golgi localization by GM130 co-staining before functional analyses. • Functional readout: rescue should restore glycomic profiles or specific glycan structures identified during knockout characterization. HEK293 transduces efficiently with lentivirus and supports stable rescue line generation.
