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)

Source / Purification

Monoclonal antibody is produced by immunizing animals with phospho-tyrosine-containing peptides . The antibody was conjugated to Alexa Fluor® 488 under optimal conditions with an F/P ratio of 2-6.

该单克隆抗体用含磷酸化酪氨酸的肽段免疫动物制备。抗体在最优条件下以F/P比2-6被偶联到Alexa Fluor® 488。

Description

Cell Signaling Technology Antibody conjugated to Alexa Fluor® 488 fluorescent dye and tested in-house for direct flow cytometric analysis of human cells. 
 
 *The unconjugated antibody, #9411, reacts with phospho-tyrosine in all species tested. CST expects that Phospho-Tyrosine Mouse mAb (P-Tyr-100) (Alexa Fluor® 488 conjugate) will also recognize phospho-tyrosine in all species.CST公司生产的抗体在最优条件下与Alexa Fluor® 488荧光染料结合,已通过在人类细胞上进行直接流式细胞反应的内部测试。*未结合抗体#9411与所有种属的磷酸化酪氨酸反应。CST预计Phospho-Tyrosine Mouse mAb (P-Tyr-100) (Alexa Fluor® 488 conjugate)也可以识别所有物种的磷酸化酪氨酸。

Background

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.

酪氨酸磷酸化在细胞信号转导中扮演重要角色(1)。在肿瘤中,失调的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导致恶性肿瘤和肿瘤形成(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高通量药物发现中为研究酪氨酸磷酸化和监测酪氨酸激酶活性提供了卓越的高灵敏的新工具。
