Methoxy PEG Succinimidyl Propionate
$160.00 – $6,400.00
Description
JenKem Technology’s Methoxy PEG Succinimidyl Propionate (Methoxy PEG Succinimidyl Propanoate, Methoxy PEG SPA, mPEG-SPA, or M-PEG SPA) is a high quality amine reactive NHS PEG product with a stable non-degradable linker between the PEG polymeric chain and the NHS ester. Methoxy PEG Succinimidyl Propionate reacts with the amine group of lysine(s), such as those on on HGH antagonist, growth hormone B2036, granulocyte colony stimulating factor MAXY-G34 (CSF MAXY-G34) [6], or uricase. Methoxy PEG Succinimidyl Propionate has a longer hydrolysis half-life compared with M-PEG-SCM.
JenKem Technology offers Methoxy PEG SPA with MW 5000 Da (M-SPA-5000), MW 10000 Da (M-SPA-10K), MW 20000 Da (M-SPA-20K), MW 30000 Da (M-SPA-30K), MW 40000 Da (M-SPA-40K) in 1g and 10g packing sizes. Different MW of Methoxy PEG SPA products may be available by custom synthesis, please email us at tech@jenkemusa.com for details on custom PEGs. Other linear JenKem NHS ester PEGs are available – if interested please select stable linker NHS PEGs, carbonate linker stable NHS PEGs, or cleavable linker NHS PEGs. JenKem Technology provides repackaging services for an additional fee, please contact us if you require a different package size than our catalog selection.
Bulk PEGs and GMP grade PEGs are made-to-order. Please contact us for bulk pricing.
