What is DIPSO?
Description
DIPSO is a Zwitterionic buffer useful in the pH range of 7.0-8.2. Studies have shown that using one buffer limits the ability to adjust the buffer capacity range. To increase the range of buffer capacity, it is more helpful to combine multiple buffers such as HEPES (sc-29097), MOPS (sc-301170), and DIPSO. This method both expands the pH buffer range and reduces toxicity by reducing the concentration of a single component.
