SNCA Knockout H4 Cell Line

The choice depends on whether you are studying α-synuclein's role in synaptic function, its aggregation behavior in Parkinson's disease, or its emerging functions in lipid biology and mitochondrial regulation. The Knockout line is the standard tool for asking whether α-synuclein is required for these processes — particularly relevant in H4 neuroglioma, a workhorse line for α-synuclein aggregation and Parkinson's disease research. Overexpression is the predominant approach for studying α-synuclein aggregation and toxicity — wild-type, A53T, A30P, E46K, and H50Q mutations have all been extensively characterized in H4. For Parkinson's disease research, the EDITGENE SNCA Knockout in H4 is the gold-standard negative control background for studying α-synuclein aggregation, fibril seeding, and clearance — H4 has extensive published α-synuclein methodology. Rescue with wild-type or PD-associated mutant α-synuclein enables comprehensive disease modeling in a clean knockout background, the preferred experimental design for aggregation studies free from endogenous wild-type α-synuclein interference.

Primary applications: • α-synuclein aggregation studies: preformed fibril (PFF) seeding assays in the knockout background to study aggregation of exogenously introduced α-synuclein variants without endogenous interference. • Parkinson's disease mutation studies: rescue with PD-associated variants (A53T, A30P, E46K, H50Q, G51D) for genotype-function studies. • Drug screening: testing α-synuclein aggregation inhibitors with the knockout as a critical negative control. • Imaging-based aggregation: pS129 α-synuclein immunostaining and inclusion body quantification following PFF or oligomer challenges. EDITGENE recommends this model for researchers investigating α-synuclein biology, Parkinson's disease aggregation mechanisms, and α-synuclein-targeted therapeutic development.

Yes. α-synuclein rescue experiments are extensively characterized in H4 background: • Construct design: use a codon-modified SNCA sequence with a small N- or C-terminal tag (HA, FLAG); both positions are tolerated but small epitope tags are strongly preferred over large fusions that disrupt aggregation behavior. • PD mutation rescue panel: A53T, A30P, E46K, H50Q, and G51D variants enable comprehensive disease genotype-function studies. • Aggregation-modulating mutations: alanine-to-proline substitutions in the NAC region or C-terminal truncations alter aggregation propensity and serve as mechanistic tools. • Functional readout: rescue should restore α-synuclein-dependent phenotypes; for aggregation studies, the knockout-rescue design eliminates endogenous wild-type α-synuclein interference with PFF seeding experiments. H4 transduces efficiently with lentivirus and supports both polyclonal and clonal rescue line generation; this background is the standard for α-synuclein aggregation methodology.
