Cre-lox (floxed) systems for gene deletion (click here for non-floxed and earlier floxed tagging vectors)General Comments. The baseline reference for this system is CRE recombinase-based positive-negative selection systems for genetic manipulation in Trypanosoma brucei (2008) Scahill MD, Pastar I & Cross GAM. Addgene has sequenced portions of this plasmid for verification. The results are shown below. Leading primers are indicated on the first line of each sequence. Primers and the results are shown below. ... Efficient gene activation in mammalian cells by using recombinant adenovirus expressing site-specific Cre recombinase ...

Cre recombinase is a bacteriophage P1 enzyme that can catalyze efficient site-specific DNA recombination between two appropriately configured 34-basepair loxP sites. Any genetic sequence of interest, if flanked by loxP sites, can be subsequently removed in the cells which express Cre recombinase (Kuhn and Torres, 2002). manner (Hoess and Abremski, 1984). Cre recombinase can be purchased relatively cheap or produced recombinantly in bacteria (Liu et al. 1998). The Cre-loxP technology has been commonly used for excision of genes in conditional gene modifications in transgenic and knockout-mice (Sauer, 1998). Recently a system based on Cre recombinase

The Cd4-Cre construct was created by replacing the the lck proximal promoter of a construct used to make a Lck-Cre Transgenic mouse (Taconic line 4197) with the mouse Cd4 promoter/enhancer/silencer, which was provided by Dr. Dan Littman and Dr. Nigel Killeen. for replication primer formation and gene expression , whereas another in vitro study argues that TEFM is a general unspecific tran- scription elongator needed for mtDNA gene expression .

Cre recombinase recombines its DNA target, loxP sites, without help of accessory proteins or DNA repair systems. The simplicity of Cre-lox system has been widely utilized for genome editing, especially in mouse genetics. The goal of this dissertation is to construct Cre recombinase variants that will operate upon recombination target sites (RTs)

INTRODUCTION. A ubiquitous promoter/enhancer to drive transgenes is a key component of a complete transgenesis toolkit in any model organism. Enhancer trap screening in the mouse previously identified the Rosa26 locus, which became the current gold standard for ubiquitous transgene expression and for Cre/loxP-based lineage tracing at all stages of development and in all adult tissues ...

May 01, 2009 · Construction of a strain with cre recombinase driven by the P ccg-1 at the his-3 locus: The cre recombinase gene of bacteriophage P1 was amplified by PCR from plasmid HZ-73 (gift of H. Zong) with forward primer #2459, which contains an XbaI site, and reverse primer #2460, which contains an EcoRI site.
Genotypes of a maA-spacer-T x hCMV-cre litter.

Upper panel: PCR genotyping of mouse tail DNA with primers indicated in Figure 1A. ‘+’ being a wild type allele and ‘ f ’ being a floxed allele; lower panel: PCR of mouse tail DNA with primers identifying . Albumin-Cre recombinase (Alb-cre). (B) Histology analysis of livers from control and LMKO mice. We are glad to present a revised version of our work “A novel mouse model of creatine transporter deficiency”. We would like to bring to your attention that we extended the measurement of creatine concentration also to body fluids, more specifically serum and urine.
pliﬁed using PCR primers 5 -GCCTGAATTCGCAGACCATGCC CAAGAAGAAGAGG-3 and 5 -GCCAGTGAATTCCTAATCGC CATCTTCCAG-3 , and then was subcloned into the EcoRI site of the pFOXJ1- -globin-polyA vector to generate a FOXJ1-Cre cDNA construct (Figure 1a). This construct was veriﬁed by sequencing and 2) If you goal is to have Tel-/- mice, you might be better off getting a CMV-Cre mouse. In your Tbx1-cre mouse, Cre recombinase is expressed under the control of the Tbx1 promoter, so just certain tissues will contain Cre recombinase to excise the DNA between your loxP sites. This link seems to give the expression pattern. StrataClone™ PCR Cloning Kit 5 StrataClone™ SoloPack® Competent Cells The provided StrataClone SoloPack competent cells express Cre recombinase, in order to circularize the linear DNA molecules produced by topoisomerase I-mediated ligation. The cells are provided in a convenient single-tube transformation format.

Jul 31, 2010 · Unique quantitative PCR (qPCR) primers were designed to facilitate a quantitative analysis of the rate of β1 loxP recombination and the rate of maintenance of the loxP-flanked DNA sequence (see Table S1 for primer sequences). The first primer set, “total-DNA,” was designed to quantify the total number of chromosomal copies in each DNA sample from a template. Brain immunohistochemistry of CRE recombinase was carried out as described by Kellendonk et al. (19). Liver slices were processed as 20 mm cryosections mounted on glass slides. For detecting recombination in the R26R allele, the following primers were used: R26F2 (5-AAAGTCGCTCTGAGTTGTTAT-3) as described by Soriano (20) and a modification of lacZ3 (21) designed in our lab (lacZ4, 5-GTGCGGGCCTCTTCGCTAT-3).
