Appearance of 3-methylmorpholinopropane sulfonic acid appears as a white crystalline powder. Application: 3-morpholinopropane sulfonic acid belongs to biological buffering agents and is often used to prepare RNA electrophoresis buffer solutions; It can not only be used as a buffer system for cell culture media, but also as a common electrophoresis buffer and protein purification chromatography buffer. Bioactive MOPS is commonly used as a buffering agent in biology. MOPS buffer can maintain the pH value of mammalian cell culture medium. MOPS buffer is a zwitterionic biological buffer widely used in cell culture, protein purification and extraction, as well as electrophoresis and other biological molecular and biochemical research. Storage conditions: 3-morpholinopropane sulfonic acid is a sulfonic acid substance and should be stored at room temperature in a dark and moisture-proof place.
