{"product_id":"sunbright-me-3e200fh-ea","title":"SUNBRIGHT® ME-3E200FH-EA","description":"\u003cp\u003eSUNBRIGHT ME-3E200FH-EA is a pH-triggered releasable PEG derivative incorporating an acid-cleavable acetal linker, designed to release conjugated pharmaceutical substances under mildly acidic conditions (pH 4–6), such as in endosomes, lysosomes, or tumor tissues. It consists of a 20 kDa PEG chain connected to an acid-cleavable linker that has a primary amine group as a functional group.\u003c\/p\u003e\u003cp\u003eThe acetal linker remains stable at physiological pH (7.4) while selectively cleaving under acidic environments to trigger drug release. The release rate can be fine-tuned by modifying the substituents on the benzene ring.\u003c\/p\u003e\u003cp\u003eME-3E200FH-EA offers excellent serum stability and storage stability, making it particularly suitable for targeted drug delivery systems requiring precise control of release timing in specific biological environments.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"NOF AMERICA","offers":[{"title":"100mg amber glass bottle","offer_id":54966329409760,"sku":"lwg1789665908688","price":150.48,"currency_code":"USD","in_stock":true},{"title":"1g amber glass bottle","offer_id":54966329442528,"sku":"oqp1789665908689","price":722.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0810\/5613\/7440\/files\/sunbright-me-3e200fh-ea_1.jpg?v=1789665912","url":"https:\/\/yogabalanceclad.shop\/products\/sunbright-me-3e200fh-ea","provider":"My Store","version":"1.0","type":"link"}
