We describe an efficient, four-step synthesis of an N 4 -modified cytidine phosphoramidite reagent ( 1 ) that permits nonnative functionality to be introduced into a synthetic oligoribonucleotide. This reagent was used to prepare a 377-nt E. coli M1

The noncovalent tetrameric active forms of avidin, concanavalin A (Con A), and adult human hemoglobin (HbA[sub 0]) can be observed intact in the gas phase by electrospray ionization mass spectrometry (ESI-MS). The atmosphere-vacuum ESI interface cond

Intact avidin-biotin and avidin-biotin maleimide noncovalent complexes have been observed by electrospray ionization mass spectrometry (ESI-MS) by using an extended mass range quadrupole mass spectrometer. By utilizing mild ESI interface conditions,

Investigations of gas-phase proton transfer reactions have been performed on protein molecular ions generated by electrospray ionization (ESI). Their reactions were studied in a heated capillary inlet/reactor prior to expansion into a quadrupole mass

The ‘softness’ of the electrospray ionization (ESI) method provides a direct link between solution chemistry and the inherent gas-phase environment of mass Spectrometry. Available results related to the preservation of non-covalent associations i

In this article, we briefly highlight the use of capillary electrophoresis for sampling, manipulating, and separating extremely small sample sizes. The extraordinary sensitivity that can be obtained by combined capillary electrophoresis-mass spectrom
