Starting with RNA—one‑step or two‑step RT‑qPCR?

When performing real-time qPCR, one has to decide whether to use a one-step protocol that combines the RT reaction and PCR in one tube, or a two-step protocol where the RT reaction is performed separately from the PCR.

How Biotin Became a Tool of Molecular Biologists

Biotechnology has an inclination towards co-opting nature’s most useful tools. The naturally occurring, extraordinarily strong bond that forms between avidins and biotin has provided a useful tool that has enabled numerous techniques that would otherwise be impossible.

Understanding Mass Spectrometry of Oligonucleotides

Oligonucleotide synthesis is a complex process that requires more than one hundred sequential chemical reactions to make a single, 25-base sequence. Contemporary synthesis chemistry is robust and modern synthesis platforms are reliable and highly automated. Still, each oligonucleotide synthesized at IDT is evaluated for quality before shipping to ensure that the correct sequence was made. The best method available to assess compound identity in a high throughput environment is mass spectrometry (MS).
