Frequently Asked Questions (FAQ)

What are phosphoramidites used for?

Phosphoramidites are activated monomers used in solid-phase DNA and RNA oligonucleotide synthesis.

What is the difference between DNA and RNA phosphoramidites?

RNA phosphoramidites include additional 2′-hydroxyl protecting groups, making them more sensitive to moisture and handling conditions.

Why is moisture control important for phosphoramidites?

Moisture can cause premature hydrolysis of phosphoramidites, reducing coupling efficiency and synthesis yield.

Can phosphoramidites be used for long oligonucleotide synthesis?

Yes, high-quality phosphoramidites are essential for achieving good yields in long and complex oligonucleotide sequences.

Are modified phosphoramidites available for custom oligos?

Modified and specialty phosphoramidites are commonly used to introduce functional groups or labels into oligonucleotides.
