Increase oligo stability with phosphorothioate modifications

Modification Highlight: Need oligos that are nuclease resistant? Phosphorothioate bonds substitute a sulfur atom for one of the non-bridging oxygen atoms in the phosphate backbone of an oligonucleotide. Resistant to both endo- and exonucleases, this linkage provides increased oligo stability.

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

Starting with RNA? 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. Here are some guidelines.

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.
