While radioactive labeling is hazardous and implicates tedious feeding experiments, the development of specific antibodies suffers from low applicability and high development costs. This is the guidebook for Exosome Research. To date, we have developed techniques for protein phosphorylation analysis using Phos-tag, a functional molecule that specifically captures a phosphate group (-PO32-). The product is used as base resin for neutral laundry detergents, dish detergents, shampoos, etc. 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. 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. iPS research.

On the other hand, samples pretreated with Phos-tag Agarose showed distinct signals, indicating an increase in phosphorylated SHC levels caused by EGF stimulation. Proteins responsible for vital cellular functions use kinase-induced phosphorylation and phosphatase-induced dephosphorylation for their activation and deactivation, respectively. The non-hazardous material is to be packed in an appropriate spin-column and can be re-used for at least 6 months, if stored at 4°C. Date of issue : April 2014 Page : 24p. 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. no warranty, express or implied, is made and labchem inc assumes no liability resulting from the use of this sds. The unique chelating properties of Phos-tag™ can be used to specifically separate, detect or purify phosphorylated molecules through gel chromatography. Therefore, the phosphorylation states of SHC after stimulation by epidermal growth factor (EGF) could not be determined. Phos-tag Agarose is also useful for the separation and enrichment of phosphopeptides from peptides mixtures in phosphoproteomics using mass spectrometry.9). Captures proteins and peptides phosphorylated on Ser, Thr, and/or Tyr residue(s).Eliminates the need for radiolabeling [RI]. Phos-tag™ is a novel phosphate-binding molecule, allowing highly selective capture of phosphoproteins at neutral pH. LabChem has been manufacturing quality laboratory solutions since 1986. 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). The reagents, protein sample preparation, and operation of electrophoresis are similar to those for the conventional SDS-PAGE procedures. ar labchem . 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. CAS RN ®: 151-21-3 Molecular Formula : CH3(CH2)11OSO3Na Molecular Weight : 288.38 GHS : Close.

Although over 60% of all cellular proteins can be phosphorylated, they dynamically change between phosphorylation and dephosphorylation states using kinase and phosphatase reactions, respectively. It has been added to the comparison table. In addition, it is widely used as an emulsifier for pharmaceuticals and cosmetics, and also for industrial use, surfactant for emulsion polymerization and scouring and cleaning agent of fiber. Our product line consists of chemical solutions prepared to exact quality standards and certified for use in laboratories and production processes. 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. 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. 1L; Poly Bottle. We hope that more researchers use Phos-tag-based techniques that contribute to diverse areas of life science. This article introduces three Phos-tag-based techniques that are used by life science researchers. Exosome Research Products Ver.2(11,200KB) This is the guidebook for Exosome Research. Coupling of Phos-tag™ with a highly cross-linked agarose resin (Phos-tag™ agarose) provides an immobilized metal ion affinity chromatography (IMAC), suitable for the preparative isolation of phosphopeptides and phosphorylated proteins. the user must determine suitability of this information for his application. Visualization of the bands is achieved in a second step and requires the usage of streptavadin-conjugated horseradish peroxidase (HRP) and chemiluminescent detection reagents.
