Tri-b-GalNAc-b-Ala-PEG3-MAL contains three terminal beta-N-acetylgalactosamine (GalNAc) sugars arranged in a trivalent configuration, facilitating high-affinity binding to the asialoglycoprotein receptor (ASGPR) expressed on hepatocyte surfaces. The crucial functional group is a terminal maleimide (MAL) moiety, enabling chemoselective bioconjugation with biomolecules harboring thiol (-SH) groups. This strategy allows for site-specific conjugation under mild conditions, valuable for developing targeted conjugates in disciplines like targeted drug delivery and antibody-drug conjugate (ADC) development for hepatocellular carcinoma.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
