Linear PEG Carbonates from JenKem Technology are activated PEGs for amine PEGylation with stable carbonate linker. Linear Succinimidyl Carbonate PEGs are reactive towards the amino group of lysine(s), with longer hydrolysis half-life compared with M-PEG-SCM. Carbonate PEGylation products with molecular weights, branching, and functional groups not listed in our online catalog may be available by custom synthesis. Please inquire at email@example.com about pricing and availability of custom PEGylation products. Bulk PEGs and GMP PEGs are also available upon request. Please contact us for special bulk pricing.
