Specificity / Sensitivity

Phospho-Tyrosine Mouse mAb (P-Tyr-100) is a high affinity antibody. ELISAs against a wide variety of phosphopeptides indicate that (a) P-Tyr-100 binds phospho-Tyr in a manner largely independent of the surrounding amino acid sequence. 2D gel Western blot analysis of pervanadate-treated cell extracts also shows that P-Tyr-100 interacts with a broad range of tyrosine-phosphorylated proteins. P-Tyr-100 does not cross-react with peptides containing phospho-Ser or phospho-Thr. (U.S. Patent No's.: 6,441,140; 6,982,318; 7,259,022; 7,344,714; U.S.S.N. 11,484,485; and all foreign equivalents.)

Phospho-Tyrosine Mouse mAb (P-Tyr-100)磷酸化酪氨酸鼠单抗亲和力非常高。ELISA中对大量磷酸化肽段的实验显示P-Tyr-100结合磷酸化酪氨酸,不受周围氨基酸序列影响。二维凝胶Western Blot分析过钒酸盐(pervanadate)处理的细胞抽提物也显示P-Tyr-100与大量酪氨酸磷酸化的蛋白质发生相互作用。P-Tyr-100不与其它含磷酸化丝氨酸或磷酸化苏氨酸的肽段发生相互作用。(美国专利号:6,441,140、6,982,318、7,259,022、7,344,714;U.S.S.N. 11,484,485;及所有国外相应专利)

Tyrosine phosphorylation plays a key role in cellular signaling (1). In cancer, unregulated tyrosine kinase activity can drive malignancy and tumor formation by generating inappropriate proliferation and survival signals (2). Antibodies specific for phospho-tyrosine (3,4) have been invaluable reagents in these studies. The phospho-tyrosine monoclonal antibodies developed by Cell Signaling Technology provide exceptionally sensitive new tools of increased utility for studying tyrosine phosphorylation and monitoring tyrosine kinase activity in high throughput drug discovery.

赖氨酸磷酸化在细胞信号转导中扮演重要角色(1)。在肿瘤中,上调酪氨酸激酶活性可以通过产生不适当的增生和存活信号而驱使恶变和肿瘤形成(2)。具有磷酸化酪氨酸特异性的抗体在这些研究中很有价值(3,4)。Cell Signaling Technology开发的磷酸化酪氨酸单克隆抗体在逐渐增加的酪氨酸磷酸化和高通量药物发现中监视酪氨酸激酶活性研究中是非常敏感的新工具。
