Mal-PEG2000-NHS ester

Mal-PEG2000-NHS ester is a heterobifunctional polyethylene glycol (PEG) derivative with a molecular weight of around 2000 Daltons. Mal-PEG2000-NHS ester features a maleimide (Mal) group on one end and an N-hydroxysuccinimide (NHS) ester on the other, making it an ideal crosslinking tool to connect amine- and thiol-containing biomolecules.

Biological Activity

Description

In Vitro

Mal-PEG5000-NHS ester acts as a heterobifunctional PEG linker, which conjugates the cyclic NGR (cNGR) peptide to thiolated branched polyethyleneimine (BPEI-SH) via a Michael addition reaction in the one-pot synthesis of the multifunctional gene vector BPEI-SS-PEG-cNGR^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
