Scientific Data Images for Cre Antibody

Western Blot: Cre Antibody [NB100-56134]

Western Blot: Cre Antibody [NB100-56134]

Western Blot: Cre Antibody - Unpurified [NB100-56134] - Lane 1: wild-type mouse (negative control). Lanes 2 and 3: brain from 2 types of Cre transgenic mice. Lane 4: recombinant Cre (positive control). Full-length Cre is detected at ~36-38 kDa. The lower molecular weight bands in lane 4 are breakdown products from the recombinant Cre protein.

Western Blot: Cre Antibody [NB100-56134] - Generation, identification, & Rpe65 expression analysis of Rpe65CreERT2 mice.(A) KI strategy to introduce a P2A-CreERT2 coding sequence in-frame with the final coding exon (exon 14) of the Rpe65 gene. Primer-binding sites & expected PCR product sizes are shown below the wild-type & targeted alleles. The neomycin cassette in the targeting vector was removed during expansion of the embryonic stem cell clone. FLP-recombinase was subsequently bred out by crossing with C57BL/6 mice. The KI allele allows cotranslational expression of RPE65-P2A & CreERT2 as 2 separate polypeptides. The modified RPE65 protein contains an additional G534SGATNFSLLKQAGDVEENPG554 polypeptide sequence at its C-terminus, while CreERT2 contains an additional Pro residue at its N-terminus. (B) Genotyping results from wild-type, Cre+/–, & Cre+/+ animals. (C) Western blot analysis of RPE65 expression. After normalization to the alpha-tubulin loading controls, the RPE65 expression levels in Cre+/– & Cre+/+ mice were estimated to be 59.7% & 1.1% of that for wild-type mice.

Background: Cre

The Cre (cyclization recombination) enzyme, a member of a large family of recombinases, recognizes loxP which is a sequence motif of 34 bp from the PI bateriophage. If a DNA seqment is flanked by two loxP sites in the same orientation, Cre excises that seqment leaving a single loxP site in the remaining DNA molecule. The excised DNA segment is subsequently degraded. Cre and lox comprise the Cre/lox system which was first developed in the late 1980's to artificially manipulate gene expression (reviewed in Branda and Dymecki, 2004; Ghosh and Duyne, 2002; and Gilbertson, 2003). As an example, mice with the Cre protein expressing in a specific cell type are bred with mice that contain a target gene surrounded by loxP sites. When the mice are bred, the cells carrying Cre will cause those cells to lose the target gene. If the Cre gene is, for example, bound to a promoter that only allows Cre production in neuronal cells, the target gene will be deleted only in those cells. Since 1989 the Cre/lox system has been used extensively and there are numerous animal, plant and bacterial stocks that already contain the Cre gene driven by ubiquitous, tissue-specific or inducible promoters and provide a quick method for breeding experiments. The Cre/lox system has the advantage of working in almost any type of cell. This has led to its application in many experiments, for example in selectively labeling neuronal cells in the brain thereby differentiating them from other types of surrounding cells.
