Product nameGold Conjugation Kit (20nm, Maleimide)
Gold Conjugation Kit (20 nm, Maleimide) (ab269902) provides an easy-to-use, one step procedure that allows researchers to covalently label proteins, peptides, oligonucleotides and other biomolecules containing primary amines with ultra-stable Gold nanoparticles with only 5 minutes hands-on time; furthermore conjugates are ready to use within 60 minutes.
This product is manufactured by Expedeon, an Abcam company. See the table below to match Abcam size against Expedeon product code.
The conjugation reacton is initiated by adding a solution of the thiol-active molecule (protein, peptide, antibody, antibody fragment or oligonucleotide) to the Gold-Maleimide nanoparticles.

Buffer Requirements for Conjugation
Free thiols (e.g. β-mercaptoethanol, DTT) must be excluded from samples and maleimide reaction buffers by desalting, because they will compete for coupling sites on the gold nanoparticles; a desalting step post reduction is mandatory if thiols are used to reduce the disulphide bonds.
Compatible buffer constituents
The kit is compatible with PBS, MOPS, HEPES, sugars, salts and detergents.
Incompatible buffer constituents
The kit is incompatible with thiol reagents.
Only purified biomolecules are suitable for use, ie. where other proteins, peptides, or amino acids are not present: antibodies in ascites fluid, serum or hybridoma culture media are incompatible.
Storage instructionsStore at -20°C. Please refer to protocols.
