社内データ

Western Blotting

Western Blotting

After the primary antibody is bound to the target protein, a complex with HRP-linked secondary antibody is formed. The LumiGLO® is added and emits light during enzyme catalyzed decomposition.

Western Blotting

Western Blotting

Western blot analysis of extracts from cells expressing different activated tyrosine kinase proteins, using Phospho-HER2/ErbB2 (Tyr1221/1222) (6B12) Rabbit mAb (upper) or Phospho-Tyrosine mAb (P-Tyr-100) #9411 (lower). Phospho-HER2/ErbB2 (Tyr1221/1222) (6B12) Rabbit mAb specifically detects phosphorylated HER2/ErbB2 but not other phosphorylated tyrosine kinases.

Western Blotting

Western Blotting

Western blot analysis of extracts from SK-BR-3 and MCF7 cells using HER2/ErbB2 (D8F12) XP® Rabbit mAb.


Western Blotting

Western Blotting

Western blot analysis of activated recombinant HER2/ErbB2 and HER1/EGFR tyrosine kinase proteins, using Phospho-HER2/ErbB2 (Tyr1248) (upper), EGF Receptor (D38B1) XP® Rabbit mAb #4267 (middle) or HER2/ErbB2 (29D8) Rabbit mAb #2165 (lower). Phospho-HER2/ErbB2 (Tyr1248) specifically detects phosphorylated HER2/ErbB2 but not phosphorylated HER1/EGFR.

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded human breast carcinoma, showing membrane localization, using Phospho-HER2/ErbB2 (Tyr1221/1222) (6B12) Rabbit mAb.

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded human breast carcinoma using HER2/ErbB2 (D8F12) XP® Rabbit mAb.


Western Blotting

Western Blotting

Western blot analysis of T47D and MCF7 cells untreated or treated with Neuregulin (100 ng/ml) for 5 minutes, using Phospho-HER2/ErbB2 (Tyr1248) Antibody (upper) or HER2/ErbB2 (D8F12) XP® Rabbit mAb #4290 (lower).

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded SkBr3 cell pellets untreated (left) EGF-treated (right) either untreated (top) or lambda-phosphatase-treated (bottom), using Phospho-HER2/ErbB2 (Tyr1221/1222) (6B12) Rabbit mAb.

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded SK-BR-3 (Her2 high, left) and MCF7 cell pellets (Her2 low, right) using HER2/ErbB2 (D8F12) XP® Rabbit mAb.


IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded human renal adenocarcinoma, using Phospho-HER2/ErbB2 (Tyr1221/1222) (6B12) Rabbit mAb in the presence of control peptide (left) or Phospho-HER2/ErbB2 (Tyr1221/1222) Blocking Peptide #1254 (right).

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded human NCI-H358 xenograft, using Phospho-HER2/ErbB2 (Tyr1221/1222) (6B12) Rabbit mAb.

IHC-F (frozen)

IHC-F (frozen)

Immunohistochemical analysis of frozen HCC827 xenograft, using Phospho-Her2/ErbB2 (Tyr1221/1222)(6B12) Rabbit mAb.


バックグラウンド

The ErbB2 (HER2) proto-oncogene encodes a 185 kDa transmembrane, receptor-like glycoprotein with intrinsic tyrosine kinase activity (1). While ErbB2 lacks an identified ligand, ErbB2 kinase activity can be activated in the absence of a ligand when overexpressed and through heteromeric associations with other ErbB family members (2). Amplification of the ErbB2 gene and overexpression of its product are detected in almost 40% of human breast cancers (3). Binding of the c-Cbl ubiquitin ligase to ErbB2 at Tyr1112 leads to ErbB2 poly-ubiquitination and enhances degradation of this kinase (4). ErbB2 is a key therapeutic target in the treatment of breast cancer and other carcinomas and targeting the regulation of ErbB2 degradation by the c-Cbl-regulated proteolytic pathway is one potential therapeutic strategy. Phosphorylation of the kinase domain residue Tyr877 of ErbB2 (homologous to Tyr416 of pp60c-Src) may be involved in regulating ErbB2 biological activity. The major autophosphorylation sites in ErbB2 are Tyr1248 and Tyr1221/1222; phosphorylation of these sites couples ErbB2 to the Ras-Raf-MAP kinase signal transduction pathway (1,5).
