The intricacies involved in setting up a scintillation counter have driven some users to newer technologies such as chromogenic, fluorescent and luminescent instruments.
Similar to EDX and attached to a SEM, it uses a crystal instead of a scintillation counter to separate and measure the characteristic X-rays given off from the sample when viewed with the electron beam.
DXA uses a collimated pencil beam (1.5 mm) of dual-energy x-rays that are aligned and connected to a scintillation counter.[4] As the patient lies on the DXA table, 2 x-ray beams pass through the body from below.
Small-angle X-ray scattering (SAXS) data were obtained with a KRM-type diffractometer (Kratky collimation; primary beam intensity control with a monitoring channel; evacuation of the sample chamber) in the range of scattering angles 20 from 3[prime] to 3 deg (copper radiation; nickel filtering of the primary beam; step-by-step scanning regime: recording of scattering radiation with a scintillation counter and digital conversion).
In experiments 1-3, a small amount of the DNA solution was transferred into a counting vial and the amount of incorporated radioactivity was measured in a liquid scintillation counter. In experiment 4, to demonstrate that the methylation of deoxycytidine residues was reduced, we performed an enzymatic hydrolysis of the isolated DNA as described below.
After 24-hr incubation with samples, cells were harvested with 50 [micro]L of cell lysis buffer (Promega) and the firefly and renilla luciferase activities were determined with the dual luciferase assay kit (Promega) by measuring luminescence with a Wallac Micro-Beta scintillation counter (PerkinElmer Life Sciences, Boston, MA, USA).
Liquid scintillation cocktail was added to each well (30 [micro]L Microscint 20; Packard), and the plates were counted using a TopCount Microplate Scintillation Counter (Packard).
The mat was cooled and then counted on a 1450 Microbeta (Perkin Elmer Life Sciences) scintillation counter.
