Proteins responsible for vital cellular functions use kinase-induced phosphorylation and phosphatase-induced dephosphorylation for their activation and deactivation, respectively. The binding affinity relies on a dinuclear 1,3-bis[bis(pyridin-2-ylmethyl)amino]propan-2-olato dizinc(II) moiety, acting as a “trap” for phosphorylations. Krafft point: 9 degrees C. Critical micelle concentration: approx. About Us; It has been added to the cart. Therefore, the technique of separation and enrichment is very attractive and useful for the analysis of such phosphorylated proteins.7).

This latter application was first described in 2005 by the group of Prof. T. Koike, who utilized the Phos-tag™ agarose to separate various phosphoproteins, such as ovalbumin, αs1‑casein, and β-casein. 1, 2) This technique uses a separation gel in which acrylamide is co-polymerized with Phos-tag Acrylamide that acts as a phosphate-trapping molecule. We examined the phosphorylated proteins present in two lysate samples of Raw 264.7 cells before and after treatment with lipopolysaccharide (LPS) and phorbol 12-myristate 13-acetate (PMA) (Figure 4).

Furthermore, these techniques can be applied to analyze proteins for which antibodies are not commercially available as well as to proteins for which the phosphorylation status is unknown.

the user must determine suitability of this information for his application. Therefore, the phosphorylation states of SHC after stimulation by epidermal growth factor (EGF) could not be determined.

The affinity of the conjugate for phosphorylated molecules relies entirely on the chelating effect of Phos-tag™, enabling a sensitivity of approx. Our product line consists of chemical solutions prepared to exact quality standards and certified for use in laboratories and production processes. It has been added to the comparison table.

Post-translational modifications (PTMs) introduce slight alterations to the physicochemical properties of specific amino acid sidechains, enabling fine tuning of the binding affinity and reactivity of target proteins.

The number of research papers citing the use of Phos-tag was approximately 500 in 2018 (based on Google Scholar results), indicating that Phos-tag is gaining interest as a standard tool for the analysis of protein phosphorylation. The cell extract samples without pretreatment showed weak signals or nonspecific signals.

In this technique, a complex is formed between Phos-tag Biotin and a horseradish peroxidase (HRP)-bound streptavidin tetramer in a 4:1 ratio, followed by probing of the blot membrane or microarray. Various kinase abnormalities have been reported in cancer and neurodegenerative disorders. We have used Phos-tag Agarose in a spin column method to analyze phosphorylated proteins.8) In this method, a simple spin column is prepared using a 0.5-mL and a 1.5-mL microtube, and the column is packed with 20 μL Phos-tag Agarose (40 μL of Phos-tag Agarose slurry).

Phosphorylated proteins that are specifically bound to Phos-tag Biotin are detected by the reaction between the chemiluminescence (ECL) substrate and HRP as enhanced ECL signals (Figure 3).1). ar lab-chem. 1 ng per band. The unique chelating properties of Phos-tag™ can be used to specifically separate, detect or purify phosphorylated molecules through gel chromatography. Phos-tag™ agarose is supplied exclusively by FUJIFILM Wako as a ready-to-use 50% (w/v) suspension in Tris‑acetate buffer with 20% (v/v) isopropanol.

Captures proteins and peptides phosphorylated on Ser, Thr, and/or Tyr residue(s).Eliminates the need for radiolabeling [RI].

It has been added to the comparison table. FUJIFILM Wako has a large selection of reference standards, standard solutions, and mixed standard solutions used for the analysis of dioxins and PCBs (polychlorinated biphenyls).

Phos-tag Biotin can be used as a molecular tool in applications such as western blotting or microarray-based methods for comprehensive detection of phosphorylated proteins. sds us labchem: information in this sds is from available published sources and is believed to be accurate. CAS RN ®: 151-21-3 Molecular Formula : CH3(CH2)11OSO3Na Molecular Weight : 288.38 GHS : Close.

Wide varieties of diseases are caused by dysregulation of kinase and phosphatase activity. To date, we have developed techniques for protein phosphorylation analysis using Phos-tag, a functional molecule that specifically captures a phosphate group (-PO32-). Owing to the commercial availability of the Phos-tag SDS-PAGE precast gels (the SuperSep Phos-tag series), this technique can be easily applied to multiple research studies.4) The banding images of phosphorylated proteins are available in the Phos-tag SDS-PAGE data collection. These results demonstrate that pretreatment of cell extract with the simple spin column using Phos-tag Agarose can dramatically improve immunoblotting of phosphorylated proteins with site-specific anti-phosphoprotein antibodies.

We have strived to evolve the endotoxin measurement technology by manufacturing lysate reagents and developing the measurement system"Toxinometer", and supported medicines from behind for over 30 years.

MicroRNA research products(7,849KB) FUJIFILM Wako offers various reagents related to microRNA.

Its product line includes chemical solutions prepared to exact quality standards and produced to specifications designed by government organizations, regulatory bodies, and commercial and trade associations.

Hence, diverse phosphorylated forms of a single protein can be detected as multiple migration bands on the gel.

Phos-tag™ is a novel phosphate-binding molecule, allowing highly selective capture of phosphoproteins at neutral pH. Certificate from here Click. While radioactive labeling is hazardous and implicates tedious feeding experiments, the development of specific antibodies suffers from low applicability and high development costs.

Furthermore, Phos-tag SDS-PAGE enables analysis of not only the Ser-, Thr- and Tyr-phosphorylated proteins, but also unstable His- and Asp-phosphorylated proteins that are involved in a two-component signaling system.3) This technique is therefore appropriate for quantitative and qualitative analyses of proteins with different phosphorylation states. In agreement with the results of several other studies on LPS/PMA signaling, we confirmed the significant increase in the levels of phosphorylation of several proteins, including Akt2, HSP27, and p38b, using the antibody microarray system with Phos-tag Biotin.

On the other hand, samples pretreated with Phos-tag Agarose showed distinct signals, indicating an increase in phosphorylated SHC levels caused by EGF stimulation. Contact Us. We hope that more researchers use Phos-tag-based techniques that contribute to diverse areas of life science.

LabChem has been manufacturing quality laboratory solutions since 1986. If the revision of product standards and packaging standards has been made, there is a case where the actual product specifications and images are different. Electrophoretic separation of phosphoproteins is achieved by using Phos-tag™ co-polymerized polyacrylamide gels. en (english us… As an exclusive distributor of Phos-tag™, FUJIFILM Wako offers a wide range of ready-to-use precast Phos-tag™ SDS-PAGE-gels (SuperSep Phos-tag™) with different acrylamide concentrations.

We regularly produce chemical solutions to specifications designed by government and regulatory bodies, commercial and trade associations, and the specific needs of individual users and businesses. It is noteworthy that Phos-tag-based techniques are used not only for the analysis of phosphoproteins in general life science research, but also for the analysis of bacterial or plant phosphoproteins that have been reported in relatively few studies.

Phos-tag SDS-PAGE revealed that the introduction of mutations can produce constitutively active MEK1 species containing phosphorylated Ser-218 and Ser-222 residues (Figure 2) and induces constitutive activity of the kinase. Recently, we analyzed different phosphorylated forms of MEK1 in cancer using Phos-tag SDS-PAGE.5) Characteristic mutations of the MEK1-coding gene have been identified in certain sporadic cancers and in MEK-inhibitor-resistant cancer cells.

The gels are co-polymerized with 50 µM Phos-tag™ and are compatible with the Mini-PROTEAN® Tetra electrophoresis chamber from Bio-Rad Laboratories Inc. and the XCell SureLock™ Mini-Cell system from Life Technologies Inc. Detection of the phosphoryl group is commonly achieved via 32P-labeling or through the usage of antibodies, specifically targeting phosphorylations.
