Specificity / Sensitivity

Phospho-Threonine-Proline Mouse mAb (P-Thr-Pro-101) detects phospho-threonine only when followed by proline. It reacts with proteins and peptides phosphorylated at the Thr-Pro motif in an otherwise highly context-independent fashion. The antibody is phospho-specific, but does not recognize phospho-threonine in the absence of an adjacent proline. The antibody does not react with phospho-tyrosine but does react with some phospho-serine peptides containing the phospho-serine-proline motif (e.g., phospho-Elk-1). (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-Threonine-Proline Mouse mAb (P-Thr-Pro-101)识别脯氨酸之前的磷酸化苏氨酸。它与磷酸化苏氨酸-脯氨酸基序发生反应,且不与背景氨基酸序列有关。此抗体是磷酸化特异性的,但是不能识别缺乏跟随脯氨酸的磷酸化苏氨酸。此抗体与磷酸化酪氨酸没有交叉反应,但与一些包含磷酸化丝氨酸-脯氨酸模体的磷酸化丝氨酸蛋白(如磷酸化Elk-1)有交叉反应。(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 synthetic phospho-threonine-proline-containing peptides . This antibody is a mouse IgM clone and can be recognized by anti-mouse Ig (whole molecule) secondary antibody.

The MAPK and CDK families of serine/threonine protein kinases play important roles in cell signaling and cell cycle control. These kinases phosphorylate threonine or serine followed by a proline residue (1-6). To study and discover new MAPK and CDK substrates, Cell Signaling Technology has developed antibodies that bind to phospho-threonine followed by proline.

MAPK和CDK丝氨酸苏氨酸蛋白激酶家族在细胞信号和周期调控中扮演重要角色。这些激酶磷酸化脯氨酸之前的苏氨酸或丝氨酸(1-6)。为了确认新的MAPK和CDK底物,Cell Signaling Technology公司开发了识别有脯氨酸之前的磷酸化苏氨酸的抗体。

As determined by ELISA using a wide variety of phospho-Thr-Pro peptides, Phospho-Threonine-Proline Monoclonal Antibody (P-Thr-Pro-101) recognizes the phospho-Thr-Pro motif in a highly context-independent fashion. It also interacts with a broad range of phospho-Thr-Pro-containing proteins as determined by western analysis of nocodazole-treated Jurkat cell extracts resolved on 2-D gels.
