{"product_id":"crhsgelpba","title":"Gel-PBA (Phenylboronic Acid Modified Gelatin) Powder for Responsive Hydrogel Synthesis, 1 g\/bottle, CRHSGelPBA","description":"\u003cp\u003eGel-PBA (Phenylboronic Acid-Modified Gelatin) is a smart, bioactive biopolymer that combines the natural cell-adhesion properties and biocompatibility of gelatin with the dynamic, stimuli-responsive cross-linking capabilities of phenylboronic acid (PBA). Because gelatin contains abundant carboxylic acid and amine residues, it can be readily functionalized with PBA to create injectable, self-healing hydrogels that respond to environmental cues such as pH changes, glucose concentrations, or reactive oxygen species (ROS).\u003c\/p\u003e\n\u003ctable style=\"width: 100.029%; height: 496.288px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0409%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.8129%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCRHSGelPBA (C-RHS-GelPBA)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 33.0409%; height: 39.2px;\"\u003e\u003cem\u003eFunction Groups in Gelatin\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.8129%; height: 39.2px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e(1) -NH2\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e(2) -COOH\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 140.4px;\"\u003e\n\u003ctd style=\"width: 33.0409%; height: 140.4px;\"\u003e\u003cem\u003eNMR\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.8129%; height: 140.4px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CRHSGelPBA_NMR_160x160.jpg?v=1792138011\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 209.6px;\"\u003e\n\u003ctd style=\"width: 33.0409%; height: 209.6px;\"\u003e\u003cem\u003eHydrogel Preparation Steps\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.8129%; height: 209.6px;\"\u003e\n\u003cp\u003e(1). \u003cstrong\u003e10-30% Gel-PBA precursor solution\u003c\/strong\u003e: Weigh certain amount of Gel-PBA powder into centrifuge tubes and add the PBS solution for fully immersion.
