The product is lyophilised, which works great when freshly reconstituted. It can be used at around 50% efficiency when thawed from -80C aliquots, but later on it doesn't work. Better than two other vendors I used.
Use at 20nM upon 2nd thaw. Store in aliquots at -80 C

Works well first time. Slightly expensive, considering you cannot use all product in a shot since acitivity drastically decreases on freeze thaw. Still better than other companies MCP1.
