This post outlines the fundamental methods for calculating the contour length—the maximum extended chain dimension—and the hydrodynamic radius, which characterizes the effective size of the solvated coil. These calculations rely on established polymer physics and empirical relations from experimental data.
PEGylation involves covalently attaching PEG molecules to protein for example, typically at specific functional groups (e.g., lysine residues or N-terminal amines). The degree of PEGylation (number of PEG molecules per protein molecule) or the total mass of PEG attached must be quantified.
Metal-Organic Frameworks – The Royal Swedish Academy of Sciences has decided to award Susumu Kitagawa, Richard Robson, and Omar M. Yaghi the Nobel Prize in Chemistry 2025, for the development of metal–organic frameworks.

Our Multi-Arm PEG Products 4-Arm PEG-X/Y Bifunctional 4-Arm PEG reagents have two functional groups X/Y with 1:3 ratio or 2:2 ratio. We started offering this series of special reagents as customs synthesis with the following combinations. We are also listing some of these reagents as regular catalog products that are ready to ship overnight. We […]
The typical PEG-maleimide-thiol reaction results in thiosuccinimide formation which is reversible, with PEG-maleimide elimination occurring slowly under biologically relevant conditions. The reversed reaction leads to the breakage of the maleimide-thiol linkage and the loss of PEG from the thiol/cysteine-containing molecules. If the maleimide-thiol chemistry does not work for your application, you may consider alternatives with […]
