Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IP=Immunoprecipitation, ChIP=Chromatin IP,

Specificity / Sensitivity

Beta-Catenin Antibody detects endogenous levels of total β-catenin protein.


Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asp56 of human β-catenin. Antibodies are purified by protein A and peptide affinity chromatography.


Western Blotting

Western Blotting

Western blot analysis of total cell extracts from 293 and NIH/3T3 cells, using β-Catenin Antibody (Amino-terminal Antigen).

使用β-Catenin Antibody(氨基末端抗原)对293和NIH/3T3细胞全细胞提取物进行western blot分析。

Chromatin IP

Chromatin IP

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 HCT116 cells and either 10 μl of β-Catenin Antibody (Amino-terminal Antigen) or 2 μl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using using SimpleChIP® Human Axin2 Intron 1 Primers #8973, SimpleChIP® Human CaMK2D Intron 3 Primers #5111, human c-Myc promoter primers, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.

使用SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003将4 x 106 HCT116细胞与 10 μl 的 β-Catenin 抗体 (氨基末端抗原)或2μl的Normal Rabbit IgG #2729交联然后进行染色质免疫共沉淀实验。富集的DNA使用SimpleChIP® Human Axin2 Intron 1 Promoter 引物 #8973, SimpleChIP® Human CaMK2D Intron 3 引物 #5111, human c-Myc promoter 引物和SimpleChIP® Human α Satellite Repeat 引物 #4486以real-time PCR的方式定量。各样品沉淀得到的DNA量相对于input染色质总量进行相对定量,Input中染色质量设定为1。


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).

β-catenin是Wnt信号通路下游的重要效应分子(1)。在脊椎动物体内它涉及到两个重要的生物过程:早期胚胎发育(2)和肿瘤发生(3)。CK1可以磷酸化β-catenin 45位丝氨酸。该磷酸化将导致β-catenin能够随后被GSK-3磷酸化(4-6)。GSK-3β通过磷酸化β-catenin Ser33, Ser37, 和 Thr41,并促使其进一步被降解(7)。这些位点发生突变会提高β-catenin蛋白稳定性,并且已在多种癌细胞株中发现这些突变(8)。
