- ‘The monomeric KpnI fragments, separated from plasmid vectors and gel purified by the spin-down method, were labeled with flourescein - 11-dUTP (Amersham Pharmacia Biotech).’
- ‘Recent measurements show that the actual characteristic spin-down period of the GP-B gyros exceeds 10,000 years-well beyond the requirement.’
- ‘However, the relationship between spin-down rate and magneto-dipole losses is not as straightforward for pulsars that also emit X-rays.’
We take a look at several popular, though confusing, punctuation marks.
