目标/特异性 | Non-phospho (Active) β-Catenin (Ser45) (D2U8Y) XP® Rabbit mAb (Alexa Fluor® 488 Conjugate) recognizes endogenous levels of β-catenin protein only when Ser45 is not phosphorylated. This direct conjugate failed to meet in-house performance critera for immunofluorescence on fixed-frozen tissue (IF-F). For this purpose, we suggest indirect detection using Non-phospho (Active) β-Catenin (Ser45) (D2U8Y) XP® Rabbit mAb #19807. |

背景 | β-Catenin is a key downstream effector in the Wnt signaling pathway (1). It is implicated in two major biological processes in vertebrates: early embryonic development (2) and tumorigenesis (3). CK1 phosphorylates β-catenin at Ser45. This phosphorylation event primes β-catenin for subsequent phosphorylation by GSK-3β (4-6). GSK-3β destabilizes β-catenin by phosphorylating it at Ser33, Ser37, and Thr41 (7). Mutations at these sites result in the stabilization of β-catenin protein levels and have been found in many tumor cell lines (8). |

Confocal immunofluorescent analysis of SW480 (left and lower right; positive) or NCI-H28 (upper right; negative) cells using Non-phospho (Active) β-Catenin (Ser45) (D2U8Y) XP® Rabbit mAb (Alexa Fluor® 488 Conjugate) in the presence of phospho-β-Catenin (Ser45) peptide (lower left) or non-phospho-β-Catenin peptide (lower right). Actin filaments were labeled with DyLight™ 554 Phalloidin #13054 (red). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye). | |
