PEG crosslinkers with Boc (tert-butyloxycarbonyl) -protected amino groups on one chain end. The Boc protecting group is stable in a wide range of conditions (including highly basic environments) but may be easily removed by (strong) acids such as TFA or at low pH in water to release the primary amine. The amine functional group at one end of the PEG linker molecule allows for selective and covalent attachment to other molecules with complementary functional groups, such as carboxylic acids or activated esters, aldehydes and epoxides. The newly formed bonds are amides, imines or secondary amines. Applicable for reversible or permanent crosslinking with PEG. 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 is necessary to obtain high pegylation yields. The PEG butyric acid NHS ester 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.

Yes, if this product requires dry ice or is classed as hazardous for transport, the additional fee will be explicitly shown in your quotation before you confirm the order, so there are no surprise charges later.
We recommend aliquoting the product upon receipt to avoid repeated freeze-thaw cycles, which can reduce activity and stability. This is your responsibility once the product has been delivered.
Recommended antigen retrieval methods, where applicable, are listed on the datasheet under the IHC protocol section.
