01 /Applications

Biological Buffering Agent

DIPSO is employed as a zwitterionic buffer in various biological and biochemical research applications. Its buffering capacity in the physiological pH range makes it ideal for maintaining stable pH in enzyme assays, electrophoresis, and cell culture systems.

Spectrophotometric Analysis

With minimal UV absorbance at 260 nm and 280 nm, DIPSO is a preferred buffer for spectrophotometric analyses. It ensures that the buffer itself does not interfere with the measurement of nucleic acids or proteins.

Cell Culture Media

This buffer can be incorporated into cell culture media to maintain optimal pH conditions for cell growth and viability. Its low toxicity and defined buffering capacity support sensitive cell lines.
