It requires a viral or genetic construct carrying the promoter and an opsin payload, plus the usual optical-delivery setup.; requires compatible viral delivery and construct design
The available evidence does not support claiming perfect specificity or performance across all cell classes.; described as enrichment rather than absolute specificity

Compared with inkube
CaMKIIα promoter-based targeting and inkube address a similar problem space because they share selection.
Shared frame: same top-level item type; shared target processes: selection
Compared with synthetic promoters
CaMKIIα promoter-based targeting and synthetic promoters address a similar problem space because they share selection.
Shared frame: same top-level item type; shared target processes: selection
Relative tradeoffs: appears more independently replicated; looks easier to implement in practice.
