General description

The development of the anti-phosphotyrosine, clone 4G10 in 1989 was a monumental discovery for researchers. 4G10 was the first and is the best single monoclonal antibody for the detection tyrosine phosphorylation. 4G10 is well known for its sensitivity and its ability to detect multiple tyrosine phosphorylations on numerous substrates. It has been validated by thousands of scientific and medical researchers in virtually every application and tyrosine target over the past 2 decades. To improve on something that hundred have tried and no one has succeeded, we pooled 4G10 with the next most highly regarded anti-phosphotyrosine, clone PY20 to make 4G10 Platinum. PY20 itself is a very poor substitute for 4G10, but its additive effect allow for a greater level of detection on more substrates that even 4G10 alone was not capable of.

Specificity

Tyrosine-phosphorylated proteins from all species

Immunogen

4G10 used Phosphotyramine coupled to KLH and PY20 used phosphotyrosine conjugated to carrier protein

Application

4G10 Platinum, Anti-Phosphotyrosine (mouse monoclonal cocktail IgG2b) detects levels of Phosphotyrosine proteins & has been published & validated for use in WB, ICC, ELISA, IHC, IF, Flow & IP.
Immunoprecipitation: 2-4 μL of a previous lot can immunoprecipitate quantitatively the phosphotyrosine containing proteins in the lysate of a confluent culture (10cm dish) of cells expressing an activated tyrosine kinase. To preserve phosphotyrosine, add 0.2 mM sodium orthovanadate to the lysis buffer.

Quality

Evaluated by Western Blot on a modified RIPA lysate from EGF-treated human A431 carcinoma cells.

Western Blot Analysis: 1:1,000-1:2,000 of this antibody detected tyrosinephosphorylated proteins in a modified RIPA lysate from EGF-treated human A431 carcinoma cells.

Target description

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

Physical form

Format: Purified
Proprietary mixture of protein G purified mouse monoclonals 4G10 (IgG2b) and PY20 (IgG2b) in 0.1 M Tris-glycine, Ph 7.4, 0.15 M NaCl, 0.05% sodium azide.
Liquid at 2-8°C.
Protein G-Sepharose Chromatography

Storage and Stability

Stable for 1 year at from date of receipt.

Analysis Note

Control
Suggested Positive Antigen Control: Cat. # 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 -20ºC. The lysate is stable for 6 months at -20ºC. Before use, add 2.5 μL of 2-mercaptoethanol per 100 μL of lysate and boil for 5 minutes to reduce the preparation. Load 20 μg of reduced lysate per lane for immunoblot analysis.

Cells must make appropriate fate decisions within a complex and dynamic environment. In vitro studies indicate that the cytoskeleton acts as an integrative platform for this environmental input. External signals regulate cytoskeletal dynamics and the cytoskeleton reciprocally modulates signal transduction.
