Application: Methanol (MeOH) has been used as an eluent in the HPLC estimation of malondialdehyde in plasma, which is an indicator of oxidative stress.It may be used in the following studies:
•Colony forming unit-fibroblast assay of bone marrow mononuclear cells.
•As solvent for the preparation of extracts of hyphae of Aspergillus for the estimation of gliotoxin by reversed phase-HPLC.
•Immunofluorescence studies.
•To compose eluent for the ion-pair reverse-phase HPLC isolation of nucleotides and their decomposition products.
