B6.Cg-Gt(ROSA)26Sortm1(CAG-HIST1H2BJ/mCherry, -EGFP/Rpl10a)Evdr/J
Cat. No.: CEMM-07250757
Common Name: H2B-TRAP; TRAP; EGFP-L10a
The H2B-TRAP allele (Translating Ribosome Affinity Purification) has a loxP-flanked STOP preventing transcription of two individual components: H2B/mCherry and EGFP/L10a. When expressed, the H2B/mCherry protein allows nuclei-labeling with mCherry (which enables nuclear isolation by fluorescence-based purification). Furthermore, EGFP/L10a fluorescently tags the translating mRNA polysome complex (which enables isolation of RNAs that are actively engaged by ribosomes). Overall, H2B-TRAP mice are a Cre-inducible tool strain that allows labeling and simultaneous isolation of cell type-specific nuclei and mRNA, and are well-suited for studying epigenomics and transcriptomics from specific cell types within a heterogeneous tissue.

| Molecular Note |
The targeting vector was designed with (from 5' to 3') with a CMV-IE enhancer/chicken beta-actin/rabbit beta-globin hybrid promoter, a FRT site, a loxP-flanked STOP, the H2B-mCherry fusion protein (coding sequence for the human histone 1 H2bj gene [HIST1H2BJ] fused in-frame to the N-terminus of a monomeric red fluorescent protein sequence [mCherry]), a 2A peptide,the EGFP-L10a fusion protein (an enhanced green fluorescent protein gene [EGFP] fused in-frame to the N-terminus of a cDNA sequence encoding the mouse 60S ribosomal subunit L10a [Rpl10a]), WPRE,a polyA signal, an AttB site, PGK-FRT Neo-PGK polyA), and an AttP site. This entire targeting vector was inserted between exons 1 and 2 of the Gt(ROSA)26Sor locus.

| Breeding Considerations |
When maintaining a live colony, heterozygous mice may be bred together, to wildtype mice from the colony or to C57BL/6J inbred mice. it has not been attempted to make this strain homozygous.
