LbaCas12a +57% Trans-Cleavage — Stronger Signal, Faster Readout

Why Trans-Cleavage Efficiency Matters?

Upon crRNA-guided recognition of target dsDNA, Cas12a unleashes robust, non-specific collateral ssDNA trans-cleavage —the mechanism that drives signal amplification and underpins attomolar sensitivity in CRISPR diagnostics.

Target recognition→Cas12a activation→ Collateral cleavage of ssDNA reporter→ Amplified fluorescence signal

Higher trans-cleavage efficiency→ Faster signal accumulation→ Lower detection limit→ Earlier readout.

This is exactly why we engineered an optimized LbaCas12a.

Key Advantage

1. +57% Trans-Cleavage Activity, Lower Detection Limits

For single-copy and ultra-low-abundance targets, the 57% activity gain delivers a stronger signal window and greater headroom to push the limit of detection (LOD) lower. Higher activity also means a stronger signal within the same reaction time—or equivalent signal in less time—which is decisive for rapid readout in point-of-care (POCT) settings.

2. Faster Signal Response, Shorter Time-to-Result

The trans-cleavage boost translates directly into shorter assay times:

• Fluorescence platforms: Faster time-to-positive(shorter time to detectable signal)
• LFA - coupled formats：30-40min sample-to-result workflow.

3. High Purity, Lot-to-lot Consistency

• Purity >95%（HPLC / SDS-PAGE verified)
• Rigorous QC ensures lot-to-lot activity consistency — essential to IVD reagent development.
