Anti-Phosphotyrosine Antibody, clone 4G10®
产品介绍:

产品说明

一般描述

Some of the tyrosine residues can be tagged with a phosphate group (phosphorylated) by protein kinases. (In its phosphorylated state, it is referred to as phosphotyrosine.). Tyrosine phosphorylation is considered as one of the key steps in signal transduction and regulation of enzymatic activity.
The advent of anti-phosphotyrosine antibodies is one of significant events in signal transduction research. Before the availability of anti-phosphotyrosine antibodies, tyrosyl phospyhorylation of proteins and enzymes was investigated through hazardous and time-consuming radioactive experiments. Anti-phosphotyrosine antibodies are commonly used in western blots after the targeted proteins have been immunoprecipitated to measure the tyrosyl phosphorylation of the proteins. Anti-phosphotyrosine antibodies are also directly used on cell lysate to examine the overall change of tyrosine phosphorylation level in reponse to various treatments.

特异性

This antibody recognizes tyrosine-phosphorylated proteins from all species.

免疫原

Phosphotyramine-KLH

应用

Anti-Phosphotyrosine Antibody, clone 4G10 detects tyrosine phosphorylated proteins in all species. This unique monoclonal antibody is validated for use in IC, IH, IP, WB and is backed by hundreds of publications.
Research Sub Category
General Post-translation Modification
Research Category

Immunoprecipitation:
2-4 μg of a previous lot immunoprecipitated quantitatively the phosphotyrosine containing proteins in the lysate of a confluent culture (10 cm dish) of cells expressing an activated tyrosine kinase. To preserve phosphotyrosine, add: 0.2 mM sodium orthovanadate to the lysis buffer.

质量

Routinely evaluated on EGF-treated human A431 carcinoma cells.

Western Blot Analysis:
0.5-2 μg/mL of this lot detected tyrosine-phosphorylated proteins in a modified RIPA lysate from EGF-treated human A431 carcinoma cells (Cohen, B., 1990; Druker, B. J.,1989; Kanakura, Y., 1991).

目标描述

Dependent upon the molecular weight of the tyrosine phosphorylated protein being detected.

外形

Format: Purified
Protein G-Sepharose Chromatography
Purified mouse monoclonal IgG2bκ in buffer containing 0.1 M Tris-glycine, pH 7.4, 0.15 M NaCl, 0.05% sodium azide. Liquid at 2-8ºC.
IgG2bκ mouse monoclonal antibody produced in vitro by mouse-mouse hybridoma 4G10 (FOX-NY [NS-1 derivative] myeloma x spleen cells).

储存及稳定性

Stable for 1 year at 2-8°C from date of receipt.

NOTE: DO NOT FREEZE.
For maximum recovery of the product, centrifuge the original vial prior to removing the cap. If the product has accidentally been frozen and thawed, spin it at 13,000 x g for 10 minutes at 2-8ºC. Save the supernatant for application.

分析说明

Control
Untreated A-431 (negative control) and EGF treated A-431 (positive control) whole cell lysates.
Included Positive Antigen Control: Catalog # 12-302, EGF-stimulated A431 cell lysate is provided as a free positive antigen control for western immunoblotting. Aliquot as desired, refreeze immediately, and store at -20°C. The lysate is stable for 6 months at -20°C. Before use, add 2.5 μL of 2-mercaptoethanol/100 μL of lysate and boil for 5 minutes to reduce the preparation. Load 20 μg of reduced lysate per lane for immunoblot analysis.

其他说明

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
