Ambion formamide has been deionized, is nuclease-free, and comes packaged as a liquid in an amber glass bottle under argon. Supplied in 5 bottles containing 500 g each. Formamide lowers the melting temperature of nucleic acid duplexes and is widely used in applications such as Southern and northern blotting, nuclease protection assays, S1 mapping, and in situ hybridization. For critical applications, it is recommended that the formamide from previously opened bottles be deionized before use.

자주 묻는 질문(FAQ)

What do you recommend for long-term storage of RNA?

For long-term storage, we recommend resuspending the RNA in stabilized formamide and storing at -70 degrees C. To remove the formamide, add 4 volumes ethanol and, if less than 20 µg RNA, also add NaCl to 0.2 M. Precipitate the RNA and use for downstream experiments.

Can a sample buffer with formamide be used with the Invitrogen TBE-Urea system?

There are many sample buffer formulations used, however we have found a distinct difference in the band appearance depending on the sample buffer composition. After evaluating urea, formamide, and various buffer systems, we found that the sharpest, flattest bands were obtained with a urea, Ficoll, and TBE buffer solution. Sample buffers made with formamide resulted in fuzzy, indistinct bands.
