Mal-PEG36-NHS ester is a polyethylene glycol (PEG)-based bifunctional linker bearing a maleimide and an N-hydroxysuccinimide (NHS) activated ester. Supplied as a research-use solid, it facilitates thiol and amine conjugation for PROTAC assembly and other bioconjugation chemistries.

• Enables thiol coupling via maleimide and amine coupling via NHS ester.
• PEG36 spacer provides hydrophilicity and flexible linker length.
• High molecular weight (≈1,923 Da) for extended linker reach.
• Purity approximately 95.0% as provided by manufacturer.
• Soluble in DMSO at ~62.5 mg/mL; documented in vivo formulations exist.
• Recommended storage: -20°C for solid; low-temperature storage for solutions to preserve stability.
• Intended for research use only; not for clinical applications.

This gene contains CAG trinucleotide repeats and encodes a protein containing several stretches of polyglutamine residues. The encoded protein may be involved in the regulation of tyrosine kinase receptor signaling. This gene is located in a chromosomal region that was genetically linked to Parkinson disease type 11, and mutations in this gene were thought to be causative for this disease. However, more recent studies in different populations have been unable to replicate this association. Alternative splicing results in multiple transcript variants.
