50 OD (585nm abs max), supplied in USP grade purified water

商品詳情參考文獻相關(guān)資料

Product Details

Composition: Methylated (methoxy-PEG-thiol, 2kDa) Gold NanoUrchins
Core Size: 50nm
Adsorption max: 585nm
OD per ml: 50 (50x more concentrated than our non-functionalized gold nanoparticles)
Particles per ml: 1.76E+12
Volume: 1ml
Formulation: Supplied in USP grade purified water

Properties

These non-protein binding methylated gold nanourchins have a narrow size distribution (CV of less than 10%), prolonged shelf-life and reduced aggregation propensity due to the protective PEG-layer.

Low batch to batch variability (+/- 2nm) assures you as a customer always end up with a product within the specified size range ordered.

All of our batches go through stringent quality control prior to shipment to our customers using dynamic light scattering to guarantee size and monodispersity and lot specifications are supplied with each product.

Storage

Store product away from direct sunlight at 4°C. Do NOT freeze. When stored as specified the product is stable for at least twelve months.
