Nanoparticle Diameter: 4 nm Oligo Length: Short (11-59 bases) mPEG: 10 kDa Volume (@ 10 OD): 1 mL Gold nanoparticles functionalized with single-stranded DNA oligonucleotides. The oligonucleotides are covalently attached to the nanoparticle surface through a thiol bond. They can be attached either through their 5' or 3' end. Oligonucleotides can be chosen to be between 11 and 90 bases long. For nucleotides of 59 bases and below, please choose "Short" option in the Oligo Length drop down box. For nucleotides between 60 and 90 bases please choose "Long" option. Please provide the sequence of the oligonucleotide in the box below. In the sequence please indicate the location of the thiol (SH) group. For example, the following sequence would be absorbed through it's 5' end: "5'--SH-ACGCGATTCGACCCTGACGATTGGC--3'" Core diameter: 4 nm – 100 nm Stabilized by PEG backfill Shelf life: > 4 months (4°C storage) Supplied as liquid suspension in PBS or in water with 0.01% (w/v) Tween-20
