Hodoodo CAT#: H556228
CAS#: 104872-42-6 (E-isomer chloride)
Description: DOTMA E-isomer is a trans-isomer of DOTMA, in which two double bonds are trans-configuration (configuration of a geometrical isomer in which two groups are on opposite sides of an imaginary reference line on the molecule). DOTMA E-isomer is a useful cationic lipid for gene transfection, nucleic acids delivery, plasmid stabilization. Note: DOTMA is the Z-isomer (or Cis-isomer) chloride salt, which CAS# is 104162-48-3. While DOTMA E-isomer (trans-isomer) chloride salt has CAS#104872-42-6. Some vendors confused each other.
