It serves as a substrate for tyrosine kinases (EGFR), which are enzymes that transfer a phosphate group from ATP to the tyrosine residues in proteins. This peptide is used in various assays to measure kinase activity, including fluorescence polarization (FP) assays and tyrosine phosphatase assays.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCAS Number:\u003c\/strong\u003e 97105-00-5\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMolecular Weight:\u003c\/strong\u003e 20,000 Da to 50,000 Da\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFormulation:\u003c\/strong\u003e 1 ml of 25mM Tris-HCl buffer (pH 7.5)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eConcentration:\u003c\/strong\u003e 1mg\/ml\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePurity:\u003c\/strong\u003e 95%\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStorage:\u003c\/strong\u003e -20 °C\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStability:\u003c\/strong\u003e 1 year\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 13px; font-weight: 700; text-transform: uppercase;\"\u003e\u003cstrong\u003eResearch use only.\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/tribioscience.com\/wp-content\/uploads\/2024\/12\/TBP0110-Poly-41-Glu-Tyr-Peptide_2024.pdf\"\u003eDatasheet (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/tribioscience.com\/wp-content\/uploads\/2024\/12\/TBP0110_Poly-41-Glu-Tyr-Peptide_MSDS.pdf\"\u003eMSDS (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TriBioScience","offers":[{"title":"Default Title","offer_id":45986503458895,"sku":"TBP0110-1MG","price":0.0,"currency_code":"ILS","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0712\/0748\/5519\/files\/TBP0110.png?v=1782812730","url":"https:\/\/www.danyel.co.il\/products\/poly-4-1-glu-tyr-peptide-tbp0110-1mg","provider":"danyel biotech","version":"1.0","type":"link"}
