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 a 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

Mouse anti-phosphotyrosine-peroxidase antibody reacts specifically with phosphorylated tyrosine coupled to BSA. The product has shown no reactivity for other phosphorylated amino acids like phosphothreonine and phosphoserine.

免疫原

与 BSA 结合的磷酸酪氨酸

应用

Monoclonal Anti-Phosphotyrosine-Peroxidase antibody has been used in

• enzyme linked immunosorbent assay (ELISA)
• dot blot
• Chemiluminescence dot blot
• kinase assay

生化/生理作用

Reversible phosphorylation of proteins is an important post-translational modification that plays a regulatory role in the expression of most proteins in the cells. Reversible phosphorylation at multiple serine, tyrosine and threonine residues mediates numerous signalling pathways in both prokaryotic and eukaryotic cells . Cellular proteins with phosphorylated tyrosine increase many fold by the activation of tyrosine kinases. Most mitogenic receptor systems such as EGF, PDGF, insulin receptors contain serine/threonine/tyrosine kinase domains that undergo autophosphorylation when receptors bind to the respective ligands. Monoclonal anti-phosphotyrosine–peroxidase antibody can be used in kinase assay to visualize the fraction of phosphorylated substrate.

外形

Lyophilized from a solution containing 1% bovine serum albumin and 0.05% MIT in 0.01 M sodium phosphate buffered saline.
