PEG crosslinking agents for biotinylation. The biotinyl functionality is used to attach avidin or streptavidin containing substrates. Pegylation by binding of biotinyl PEG to avidin and streptavidin is very specific and fast. PEG-NHS derivatives are active esters and useful reagents to pegylate proteines, peptides or any other surfaces with a free primary amino group to form stable amide bonds. The Reaction requires a neutral to alkaline pH (7 to 8.5) to proceed. However, hydrolysis competes with aminolysis of the active ester and also increases with higher pH. Thus, working with excess PEG-NHS ester is necessary to obtain high pegylation yields. The PEG butyric acid NHS derivative has a C4 chain directly attached to PEG. It is one of the most stable PEG NHS esters known with a hydrolysis half-life of over 20 min at pH 8.

Lead times depend on the product type: custom polyclonal antibodies typically take 12-14 weeks, monoclonal antibodies 15-17 weeks, made-to-order recombinant proteins 4-8 weeks, and made-to-order recombinant antibodies 6-8 weeks. These are estimates and may shift due to production delays.
A recommended dilution range for each validated application is provided on the datasheet, but optimal dilution should be titrated for your specific experimental system, sample type, and detection method.
Post-reconstitution storage guidance is listed on the datasheet, typically requiring aliquoting and storage at -20°C or -80°C to preserve activity.
