Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (NBP3-32219) at 1/1,000 dilution was used in 5% NFDM/TBST at room temperature for 2 hours. Goat Anti-Rabbit IgG - HRP Secondary Antibody at 1/50,000 dilution was used for 1 hour at room temperature.
Cre Antibody (PSH01-93)

Immunohistochemistry: Cre Antibody (PSH01-93) [NBP3-32219]

Immunohistochemistry: Cre Antibody (PSH01-93) [NBP3-32219] - Immunofluorescence analysis of paraffin-embedded 293T transfacted with or without Cre cells labeling Cre recombinase with Rabbit anti-Cre antibody (NBP3-32219) at 1/20,000 dilution.

The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 2 minutes. The tissues were blocked in 10% negative goat serum for 1 hour at room temperature, washed with PBS, and then probed with the primary antibody (NBP3-32219, green) at 1/20,000 dilution overnight at 4 ℃, washed with PBS. Goat Anti-Rabbit IgG H&L (iFluor™ 488) was used as the secondary antibody at 1/1,000 dilution. Nuclei were counterstained with DAPI (blue).

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. This Cre antibody recognizes the recombinase protein, Cre. Cre is a 343 amino acid protein, GenBank no. AAQ14086.1.
