SD0031 is referred as phiX174 RF1 DNA under Thermo Fisher Scientific catalogue. SD0031 phiX174 RF1 DNA is applicable in Preparation of DNA molecular weight standards . It is a isolated from Isolated from E. coli HF4704 infected with phiX174 am3. More than 90% of this DNA is in the supercoiled form. It is purified by chromatography using proprietary patented technology. After entering the cell, phiX174 DNA is utilized as a template for minus-strand synthesis, producing double-stranded DNA. The conversion of plus DNA strands to double-stranded DNA does not require any of the phage genes to function.

Specifications: SD0031 phiX174 RF1 DNA should be stored at -20C.The unit size is 50 g.
