产品说明

一般描述

Monoclonal Anti-Phosphotyrosine (mouse IgG1 isotype) is derived from the PT-66 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with phosphotyrosine-BSA conjugate.
经 ELISA 和竞争性 ELISA 确定，该抗体与磷酸化的酪氨酸特异性反应，该磷酸化的酪氨酸既可以是游离氨基酸形式，也可与 BSA 或 KLH 等载体结合的形式。与非磷酸化的酪氨酸、磷酸苏氨酸、磷酸丝氨酸、AMP 或 ATP 没有观察到交叉反应。

特异性

Monoclonal Anti-Phosphotyrosine is specific for phosphorylated tyrosine both as the free amino acid or when conjugated to carriers such as BSA or KLH. It does not react with non-phosphorylated tyrosine or other phosphorylated amino acids, including serine

免疫原

生化/生理作用

Protein phosphorylation is a basic signaling mechanism that modifies protein function in eukaryotic cells. Serine, threonine, and tyrosine are the major phosphorylated amino acids in proteins. Tyrosine phosphorylation is a rare post-translational event in normal tissues, accounting for only 0.03% of phosphorylated amino acids. However, this phosphorylation increases several folds by various activation signals and the process is mediated by protein tyrosine kinases. Protein-tyrosine kinases (PTKs) are enzymes that catalyze the transfer of γ-phosphate of ATP to tyrosine residues of protein substrates. The PTKs are responsible for many biological processes like cell cycle, proliferation, oncogenesis, and development.
