APOD Knockout HEK293T Cell Line

The choice depends on whether you are studying APOD (apolipoprotein D)'s role as a lipocalin family secreted protein or modeling its functions in neurodegeneration and emerging biology. The Knockout line is the standard tool for asking whether APOD is required for these processes — APOD is an atypical apolipoprotein belonging to the lipocalin family (unlike other apolipoproteins which are amphipathic helix-rich); APOD has a typical lipocalin β-barrel that binds hydrophobic ligands (progesterone, pregnenolone, arachidonic acid, possibly oxidized lipids); APOD is highly expressed in nervous system and is a major component of breast cyst fluid. Overexpression is useful for studying APOD gain-of-function effects. For APOD research, the EDITGENE APOD Knockout in HEK293T is a workhorse mechanistic platform. This product complements the parallel APOD Knockout in A-549 (also available) for cross-background validation. Rescue with wild-type APOD is the standard specificity control. The knockout is valuable for studying lipocalin family biology, neuroprotection mechanisms (APOD upregulation in aging and neurodegeneration), and emerging APOD-related biology.

Primary applications: • Lipocalin family biology: hydrophobic ligand (progesterone, arachidonic acid, oxidized lipids) binding analysis. • Secreted lipocalin biology: conditioned media APOD analysis. • Cross-background validation: parallel analysis with APOD KO in A-549 (also available). • Discovery proteomics: APOD-binding partner identification in APOD-null versus rescued cells. EDITGENE recommends this HEK293T-based model for systematic APOD biochemistry.

Yes. APOD rescue experiments require attention to secreted lipocalin architecture: • Construct design: use a codon-modified APOD sequence with a small N-terminal tag (FLAG, HA, after signal peptide cleavage) or C-terminal tag carefully placed. APOD has signal peptide and mature lipocalin β-barrel domain — preserve protein integrity. • Secretion validation: confirm conditioned media APOD secretion. • Ligand-binding-deficient rescue: β-barrel cavity mutations disrupt hydrophobic ligand binding. • Functional readout: rescue should restore APOD-dependent phenotypes identified during knockout characterization. HEK293T transduces with very high efficiency and supports stable rescue line generation.
