B36: Aldh1L1-optoα1AR-IRES-lacZ Strain Information Sheet

indicate interest

Strain Name:

Common Name: Aldh1L1-optoα1AR-IRES-lacZ

CHROMusTM designation and lines available: R24:B36

Jackson Stock number: NA

Development: The rhodopsin based effector, optoα1AR which on activation generates the second messenger diacylglycerol/IP3, was inserted at the ATG site of the Aldh1L1 gene in the BAC RP23-7M9 (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
50 9 2

Description: The rhodopsin based effector, optoα1AR is expressed under control of the Aldh1L1 promoter, directing expression to astrocytes.  Expression is observed in the brain. 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 neuronal cells.  NOTE: functional analysis of this mouse line is ongoing.

Phenotypic Data:

Functional analysis is ongoing. LacZ staining of the brain shows appropriate expression patterns.
