SNAP23 & STX7 Knockout HEK293T Cell Line

The choice depends on whether you are studying combined Q-SNARE function in endolysosomal fusion or distinguishing SNAP23's roles in different fusion compartments. The Double Knockout line is uniquely valuable for asking whether SNAP23 and STX7 function together — these SNAREs partner in late endosomal/lysosomal fusion events that single knockouts cannot fully reveal. Overexpression of either SNARE in the double knockout is useful for sufficiency testing and for rescue with SNARE variants. For endolysosomal SNARE research, the EDITGENE SNAP23 & STX7 Double Knockout in HEK293T is highly informative — STX7 is a late endosomal/lysosomal syntaxin that partners with SNAP23 in heterotypic membrane fusion. Single-SNARE rescue (SNAP23 alone or STX7 alone) in the double knockout dissects independent versus partnered functions. Rescue with both SNAREs restores combined fusion capacity. This combinatorial approach is the gold standard for studying compartment-specific SNARE biology.

Primary applications: • Endolysosomal fusion: late endosome-lysosome fusion assays using fluorescent cargo tracking to assess combined SNAP23-STX7 function. • Single-SNARE rescue: re-introduction of SNAP23 alone or STX7 alone in the double knockout enables direct dissection of independent versus partnered functions. • Cathepsin processing: pro-cathepsin maturation analysis given the dependence on late endosome-lysosome fusion. • Autophagic flux: LC3 and p62 dynamics following autophagy induction, given the requirement for autophagolysosome fusion. EDITGENE recommends this model for researchers investigating endolysosomal SNARE biology and combinatorial Q-SNARE function in late endocytic compartments.

Yes, and rescue experiments are uniquely powerful in this double knockout background: • Single-SNARE rescue: re-introduction of SNAP23 alone or STX7 alone enables dissection of independent functions — the gold-standard experimental design for partnered Q-SNARE biology. • Combined rescue: simultaneous SNAP23 + STX7 re-expression restores partnered fusion capacity and serves as the positive control. • Construct design: codon-modified SNAP23 and STX7 sequences with small tags (FLAG, HA). Both are essential for late endosomal/lysosomal fusion — preserve SNARE motifs and transmembrane anchoring. • Functional readout: late endosome-lysosome fusion assays, cathepsin maturation, and autophagic flux to confirm restoration of combined SNARE function. HEK293T's very high transfection efficiency enables combinatorial rescue experiments that would be difficult to execute in less efficient cell lines.
