General Information:	Beta-Catenin is a 88 kDa protein which is exprimed in many different tissues. Normally it is located in the cytoplasm near the cell membrane. It is associated with E-Cadherin and it may be essential for the function of this protein. Mutations in Beta-Catenin Gen CTNNBT1 lead to a loss of membrane binding and to an accumulation of the protein in the nuclear region. Nuclear accumulation is found especially in fibromatous lesions of the breast and abdomen. Therefore the antibody has been used for differentiation of these lesions from other spindle cell tumors, which may occur in the named body regions. Nuclear Accumulation of beta-Catenin was also found in colo-rectal carcinoma.

Special properties:

Positive control:	Fibromatosis, Colon Carcinoma

Pre-treatment:	Formalin-fixed materials require heat induced antigen retrieval with citrate buffer (Art. No. DE000) or TEC-Buffer pH 8 (Art. No. DE005). We recommend an unmasking procedure for 30 min at 100°C.

Applications:	IHC(C, P), WB

Secondary reagents:	Anti-rabbit IgG:Biotin conjugate (code no. ZU101) in conjunction with Streptavidin-HRPO (code no. ZU054) or VECTOR ImmPress rabbit IgG Kit (code no. MP-7401).

Storage:	2-8°C

UniProt Accession No.: P35222 (CTNB1_HUMAN)
