Cancer

Mal-amide-PEG8-Val-Cit-PAB-OH is a cleavable ADC linker featuring a maleimide, a hydrophilic PEG spacer, a Val-Cit dipeptide, and a PAB functional group. Maleimide is used to covalently bind free thiols on the cysteine residues of proteins. The Val-Cit dipeptide is cleaved by cellular proteases within the cell to allow for efficient payload delivery with the help of the PAB structure.

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.

BP Fluor 532 maleimide is a photostable, bright yellow-fluorescent dye with pH insensitive emission from pH 4 to pH 10. The excitation of BP Fluor 532 is ideally suited for the frequency-doubled Nd:YAG laser line. BP Fluor 532 dye can be conjugated to a variety of antibodies, peptides, proteins, tracers, and amplification substrates, and is often used for the generation of stable signals in imaging and flow cytometry. Maleimide is the most popular sulfhydryl-reactive group for conjugating the dye to a thiol group on a protein, oligonucleotide thiophosphate, or low molecular weight ligand. The maleimide group specifically and efficiently reacts with reduced thiols (sulfhydryl groups, –SH) at pH 6.5 to 7.5 to form a stable thioether bond. The resulting conjugates exhibit brighter fluorescence and greater photostability than the conjugates of many other spectrally similar fluorophores.
