B26: cdh5-optoα1AR-IRES-lacZ Strain Information Sheet


Strain Name:

Common Name: cdh5-optoα1AR-IRES-lacZ

CHROMusTM designation and lines available: R24:B26

Jackson Stock number:  Jax# 033343

Development: The rhodopsin based effector, optoα1AR which on activation generates the second messenger diacylglycerol/IP3, 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
64 9 tbd 1+

Description: The rhodopsin based effector, optoα1AR is expressed under control of the cdh5 promoter, directing expression to endothelial cells. Expression is observed in endothelial cells of vessels. An internal ribosome entry site (IRES) allows for co-expression of lacZ as a visual indicator of expression patterns. This mouse is useful for activating second messengers in endothelial cells.

Phenotypic Data:

Functional analysis is ongoing.  LacZ staining of heart, brain and lung shows appropriate expression patterns.
