TCO4-PEG3-Maleimide is a PROTAC linker and belongs to the PEG class. TCO4-PEG3-Maleimide contains TCO and Maleimide groups, which can undergo specific "click" reactions with tetrazine groups or thiol groups, or "mercapto-acrylamide" reactions.

HY-W591360

Iodoacetamido-PEG6-azide		Azide
Iodoacetamido-PEG6-azide is an aqueous soluble PEG linker containing an azide and a terminal Iodoacetamido group. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The Iodoacetamido moiety is commonly used to bind covalently with the thiol group of cysteine so the protein cannot form disulfide bonds.

DSPE-PEG-SH, MW 2000		Pegylated Lipids
DSPE-PEG-SH, MW 2000 is a pegylated phospholipid with thiol group which is reactive with maleimide to form a covalent thioether linkage. The amphiphatic polymer can form lipid bilayer in aqueous solution and be used to encapsulate agents for drug delivery system, such as mRNA vaccine.

HY-W800805

DOPE-Mal		Phospholipids
DOPE-Mal is a synthetic analog of naturally-occurring PE containing 18:1 fatty acids at the sn-1 and sn-2 positions with a terminal maliemide group. The maleimide group will react with a thiol group to form a covalent bond. The hydrophilic PEG spacer increases solubility in aqueous media.

HY-W441004

DSPE-Thiol		Phospholipids
DSPE-Thiol is a phophalipid capped with thiol group. The thiol capped head can selectively react with maleimide. DSPE-Thiol can also be used for the preparation of phospholipid dimers .

HY-W590555

Thiol-PEG-DMG, MW 2000		Pegylated Lipids
Thiol-PEG-DMG, MW 2000 is a phospholipid polyPEG which can be used to prepare liposomes or nanoparticles. The terminal thiol group reacts with maleimide, OPSS, vinylsulfone and transition metal surfaces including gold, silver, etc.
