一般說明

Chloroform, a halogenated hydrocarbon, is widely employed as a solvent. Its photochemical degradation has been investigated in the presence of TiO2 aqueous suspensions (wavelength range of 310-380nm).

應用

Chloroform may be employed as a solvent for the following studies:
  • Extraction of RNA from plant cells.
  • Preparation of dioleoylphosphatidylcholine (DOPC) solution.
  • Dissolution of 1,2-distearoyl-sn-glycero-3-phosphocholine (DSPC).
It may be employed in a rapid quantitative method for the release of periplasmic proteins from bacterial strains.
Chloroform may be used as a solvent to enhance the enantioselectivity of secondary alcohols formed by the borohydride reduction of carbonyl compounds in the presence of optically active ketoiminatocobalt complexes.

We have used magnetic alternating current mode atomic force microscopy (MAC-AFM) to investigate the formation of supported phospholipid bilayers (SPB) by the method of vesicle fusion. The systems studied were dioleoylphosphatidylcholine (DOPC) on mica and mica modified with 3-aminopropyl-triethoxy-silane (APTES)
