In native MS experiments, protein samples, prepared at neutral pH in aqueous buffers, are ionized, desolvated or partially desolvated, and introduced into the gas phase using nanoelectrospray ionization (nano-ESI).
GaAs (001) wafer pieces with a previously grown GaAs buffer were In-glued on the 2″ Si wafer and introduced into the MBE and preheated at 300 °C.
The actin-containing solution was mixed with imaging buffer (catalase, β-mercaptoethanol, glucose oxidase, 0.8% [vol/vol] D-glucose, 0.25% [wt/vol] methylcellulose, and 1/10 volume of 10x KMEI buffer [500 mM KCl, 20 mM MgCl2, 20 mM EGTA, and 300 mM imidazole], with a final pH of 7.1) and introduced into the flow cell.
Immunomagnetically labeled whole blood and buffer are introduced into the first compartment via two input channels.
The sample and buffer are introduced into the channel from the two inlets located on the left.
Following bead loading, lysis buffer was introduced into the array, and the array was then immediately sealed by introducing fluorinated oil.
These pathways were shown to control the spatial distribution of the injected EVO, and a bicarbonate buffer introduced into the cell for pH control.
Injections of 1 μL of a concentration of 20 μmol L−1 in digestion buffer were introduced into the reactor that was kept at the indicated temperature using a water bath.
ICAM1-TagBFP and pMHC were further diluted with imaging buffer, introduced into the flow cells, and incubated for 35 min followed by a rinse with imaging buffer.
Buffer solutions and equipment introduced into the chamber need to be deoxygenized overnight prior to use in experiments.
