•Simple RP-HPLC method for quantification of free and total thiols using 4,4'-Dithiodipyridine (DTDP).•High recovery rates for free and total thiols.•High stability within 24 h.RNAs have been elucidated to play the critical role in regulating gene expression and to be expected as effective drugs in the treatment of cancer and age-related diseases. RNAs are extracted by SDS-NaCl centrifugation after transformation of E.coli by expression vectors, which is a method to obtain genetically engineered RNAs. But the prepared RNAs by this met
