Cx3cr1gfp mice jax 005582
The Cx3cr1GFP mice (JAX # 005582) are a transgenic mouse line that expresses green fluorescent protein (GFP) under the control of the Cx3cr1 promoter. Cx3cr1 is a chemokine receptor expressed on monocytes, macrophages, and dendritic cells. The GFP expression in these cells allows for their visualization and tracking in vivo.

Microglia-Specific Calcium Imaging in Mice
Ai96 (RCL-GCaMP6s) were maintained as homozygous. Cx3Cr1 CreER : RCL-GCaMP6s were obtained by crossing Cx3Cr1 CreER heterozygous mice with Ai96 (RCL-GCaMP6s) homozygous mice and screening Cx3Cr1 CreER heterozygous offsprings by PCR genotyping. Tamoxifen (75 mg/kg) was given intraperitoneally for 5 consecutive days at the age of two months to activate CreERT2 recombinase, which can excise the stop cassette in the genomic DNA of Cx3Cr1CreER: RCL-GCaMP6s mice and thus allow the transcription of downstream GCaMP6s. LPS from Escherichia coli O127:B8 (Sigma, L5024) was injected intraperitoneally (5 µg/g body weight) and brain tissue was collected 16 hours after injection. Both males and female were used and balanced numbers of sexes were mixed in our analysis and reports.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
