Description

The eSpCas9 mRNA expresses enhanced-specificity SpCas9 protein, with sequence originally from Slaymaker et al., Science (2015 Dec 1). eSpCas9 significantly reduces off-target effects (by more than 10-fold), while maintaining high on-target genome editing efficiency.

This mRNA features:
- A modified 2′-O-ethyl-Cap1 structure with high capping efficiency for enhanced translation and extended intracellular stability
- 100% substitution with N1-methyl-pseudouridine (m1Ψ) for improved protein expression and reduced innate immune activation
- A 100A poly(A) tail to mimic mature mRNA

This construct provides a high-specificity CRISPR editing reagent, ideal for precise genome modification and functional genomics research.

应用指导

Transfect 1 µg of mRNA into one well of cells in a 24-well plate using 1 µL of Lipofectamine™ MessengerMAX™ Transfection Reagent (or an equivalent reagent), following the manufacturer’s instructions. Samples were analyzed at 24, 48, and 72 hours post-transfection using an ELISA assay.
