B38: Ly6G-optoβ2AR-IRES-mVermilion Strain Information Sheet

indicate interest

Strain Name:

Common Name: Ly6G-optoβ2AR-IRES-mVermilion

CHROMusTM designation and lines available: R24:B38

Jackson Stock number: NA

Development: The rhodopsin based effector, optoβ2AR which on activation generates the second messenger cyclic AMP was inserted at the ATG site of the Ly6G gene in the BAC RP24-268F10 (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
53 21 1

Description: The rhodopsin based effector, optoβ2AR is expressed under control of the Ly6G promoter, directing expression to neutrophils.  An internal ribosome entry site (IRES) allows for co-expression of the red fluorescent protein mVermilion as a visual indicator of expression patterns. This mouse is useful for activating second messengers in neutrophils.

Phenotypic Data:

NOTE:  Functional analysis is ongoing.  Quantitative PCR analysis indicates Line 16 expresses the mRNA for optoβ2AR.

Quantitative PCR analysis of the white blood cell fraction in blood. Line 16 shows an increased level of optob2AR message compared to other lines.
