T-Boc-N-Amido-PEG6-Amine With CAS NO .1091627-77-8 Of Poly Ethylene Glycol Is Applicated In
|Storage:||-20℃ for Long Term|
T-Boc-N-Amido-PEG6-Amine With CAS NO .1091627-77-8 is an amine-reactive reagent with an extended spacer arm. This
reagent is soluble in organic solvents such as DMSO or DMF. Once
dissolved in an organic solvent, the reagent is further diluted in
a non-amine containing aqueous buffer. NHS esters react efficiently
with primary amino groups (-NH2) in pH 7-9 buffers to form stable
amide bonds. Because antibodies and other proteins generally
contain multiple lysine (K) residues in addition to the N-terminus
of each polypeptide, they have multiple primary amines available as
targets for labeling with NHS-activated PEG reagents.
Important Product Information:
T-Boc-N-Amido-PEG6-Amine With CAS NO .1091627-77-8 is moisture-sensitive. Store the vial of the reagent at -20°C with
desiccant. To avoid moisture condensation onto the product,
equilibrate vial to room temperature before opening.
Dissolve NHS-PEG-linker immediately before use. The NHS-ester
moiety readily hydrolyzes and becomes non-reactive; therefore,
weigh and dissolve only a small amount of the reagent at a time and
do not prepare stock solutions for storage. Discard any unused
• Avoid buffers containing primary amines (e.g., Tris or glycine)
as these compete with the intended reaction. If necessary, dialyze
or otherwise desalt to exchange the protein sample into an
amine-free buffer such as phosphate buffered saline.
