AAV with cTNT promoter driven CreERT2
This AAV expresses CreERT2 driven by a cardiac cTNT promoter.
cTNT promoter is a 0.4 Kb fragment derived from the chicken troponin T gene, and drives cardiomyocyte muscle-specific gene expression.
A mutated form of estrogen ligand-binding domain (ERT2) that binds to synthetic antagonists (such as tamoxifen or its derivative 4-hydroxy-tamoxifen) but not to circulating estrogen, was fused to the Cre recombinase (Cre) to create CreERT2 (also known as “inducible Cre”). When tamoxifen binds to CreERT2, it induces a conformational change of CreERT2, leading to its nuclear translocation, followed by Cre/Lox-mediated recombination.
Ready-to-use AAV expressing CreERT2 driven by a cardiac cTNT promoter. Available in AAV1, AAV2, AAV5, AAV6, AAV8, AAV9, AAV-DJ and other serotypes.
