cdh5-GCaMP8 Strain Information Sheet
Strain Name:
Common Name: cdh5-GCaMP8
CHROMusTM designation and lines available: R24:B20
Jackson Stock number: Jax# 033342
Development: The green fluorescent calcium indicator GCaMP8 was inserted at the ATG site of the cdh5 gene in the BAC RP23-453P1 (CHORI) through homologous recombination. The resulting recombinant BAC was injected into the male pronucleus of fertilized oocytes which were then implanted into pseudo pregnant females. Resulting offspring were screened for the presence of the transgene (founders). Colonies were established from each founder and tested for expression.
Transgenic Numbers:
| # pups born | # founders | # expressors |
| 47 | 17 | 7+ |
Description: The genetically encoded calcium indicator GCaMP8 is expressed under control of the cdh5 promoter, directing expression to endothelial cells. Expression is observed in endothelial cells of vessels. GCaMP8 responds to calcium levels in the cell. When calcium increases, a conformation change occurs resulting in an increase in fluorescence. When calcium decreases, fluorescence decreases. This mouse is useful for examining calcium signaling in endothelial cells.
Phenotypic Data:
Native fluorescence of GCaMP8 expressed in endothelial cells under control of cdh5 promoter.
anti-gfp staining of GCaMP8 protein expressed in endothelial cells under control of cdh5 promoter.
