Published Workflows
Objective: Engineer a genetically encoded turn-on fluorescent biosensor for rapid, convenient, non-invasive, and specific detection of living endothelial cells without immunostaining.
Why it works: The abstract states that a high-affinity endothelial-recognition peptide was combined with a turn-on EGFP architecture so that fluorescence is activated only upon binding to endothelial cells.

Implementation Constraints
cofactor dependency: cofactor requirement unknownencoding mode: genetically encodedimplementation constraint: context specific validationoperating role: sensor
The biosensor includes the endothelial-recognition peptide E12P and a turn-on EGFP fused with two linker peptides. Use requires live-cell fluorescence imaging.; requires the E12P endothelial-recognition peptide component; requires a turn-on EGFP fused with two linker peptides
Independent follow-up evidence is still limited. Validation breadth across biological contexts is still narrow. Independent reuse still looks limited, so the evidence base may be fragile. No canonical validation observations are stored yet, so context-specific performance remains under-specified.
