Thermo Fisher, J62446.AP, CAPS, 0.5M buffer soln., pH 10.5

Quantity: 500 mL
Unit Size: Each
ApplicationsCAPS (N-cyclohexyl-3-aminopropanesulfonic acid) buffer salt is used to formulate CAPS buffer, a zwitterionic buffer that is useful in the range of pH 7.9-11.1. CAPS buffer is widely used in Western and immunoblotting experiments as well as protein sequencing and identification. Used in the electrotransfer of proteins to PVDF (sc-3723) or nitrocellulose membranes (sc-3718, sc-3724). The high pH of this buffer makes it useful for the transfer of proteins with a pI>8.5. CAPS is not one of the original Good’s buffers, although it has a similar structure to the other propanesulfonic acids and was selected as a highly water soluble buffering reagent with an optimum buffering pH of 10.4 and minimal reactivity with enzymes or proteins, minimal salt effects.SolubilitySoluble in water (100 g/L) at 20°C, and methanol (1%).NotesStore at room temperature. Ensure good ventilation. Incompatible with oxidizing agents.
