We have modified recombinant interleukin-2 (rIL-2) to facilitate site-directed covalent attachment of monomethoxy polyethylene glycol (PEG). The site chosen for modification and subsequent covalent attachment with PEG (PEGylation) was the single glycosylation position found in the native interleukin-2 (IL-2). The

Site-specific mono-PEGylations were performed in different conformational regions of Thymosin alpha 1 (T alpha 1) by introducing one cysteine residue into the chosen site and coupling with thiol-specific mPEG-MAL reagent. Results demonstrated that PEGylated sites and regions influenced the conformations

The design of the extension arm-facilitated PEGylation (EAFP) of proteins takes advantage of the high selective and quantitative aspects of the thiol-maleimide reaction. However, the efficiency of EAFP with hemoglobin varied with the batches of maleimide-PEG. The low level of

Sphingolipids are diverse lipids with essential, and occasionally opposing, functions in the cell and therefore tight control over biosynthesis is vital. Mechanisms governing this regulation are not understood. Initial steps in sphingolipid biosynthesis take place on the cytosolic face of
