The AURION Gold Tracers are available in the full range of particle sizes: Ultra Small, 6, 10, 15 and 25 nm. Anionic Gold Tracers are prepared with BSA-c™ as particle conjugated protein.
AURION Gold Tracers are available in 5 and 10 ml volume packages and are supplied at an OD520nm of 2.0 for the conventional particle size range and at equivalent OD for the Ultra Small tracers.
The products are supplied in PBS, with 15 mM NaN3.
AURION Gold Tracers are also available in bulk and at different optical density if required.
AURION Gold Tracers are shipped containing NaN3 as preservative. If they are intended for use in living organisms, the preservative has to be removed prior to use. This can be achieved either by dialysis or by buffer exchange using for instance a GE Healthcare Life Sciences PD-10 column.
