Hydrogenation Shaker Apparatus, Parr Instrument Company

Catalog Number: (19790-000)
Supplier: Parr Instrument
Description: Materials to be treated in a Parr hydrogenator are sealed in a reaction bottle with a catalyst and connected to a hydrogen reservoir. Air is removed either by evacuating the bottle or by flushing with hydrogen. Pressure is then applied from the reservoir and the bottle is shaken vigorously to initiate the reaction. The bottle can be heated or cooled during this process, if necessary. After the reaction reaches the desired point, the shaker is stopped, the bottle vented and the product and catalyst are recovered.

DPA/Terbium set for membrane fusion assay

Catalog Number: (89139-510)
Supplier: Biotium
Description: The principle of DPA/Tb3 for vesicle fusion assay is based on the fact that contact of the chelator dipicolinic acid (DPA) with terbium (III) forms an instant Tb3 -DPA complex that is ~10,000 times more fluorescent than free Tb3 . In the assay, separate vesicle populations are loaded with 2.5 mM TbCl3 in 50 mM sodium citrate, or 50 mM DPA in 20 mM NaCl.
