The complexation of
uranyl ions with amidoximated PAN-DVB-EGDMA beads leading to the formation of amidoxime
uranyl ion complex, can be represented as shown in Fig.
Resin blocks were trimmed perpendicular to the long axis of the muscle fibers and ultra-thin sections (60 nm thick) were collected on Formvar-coated copper slot grids and contrasted with
uranyl acetate (5% aqueous) followed by lead citrate, 1 minute each.

To determine whether the postfixation staining with lead citrate was responsible for dissolution of the electron-dense platelets, as had previously been reported for purine-based crystals (Schmitter, 1971; Land, 1972; Levy-Lior et al., 2010; Mueller and Labhart, 2010), fixed sections were treated with only lead citrate, only
uranyl acetate, both compounds, or neither compound.
Figures 3(a) and 3(b) show TEM images of synthesized UDCA-PA nanoparticles dispersed on a carbon coated copper grid and negatively stained with 1% (w/v)
uranyl acetate solution.
This is also the case for
uranyl fluoride complexes discussed in Section 3.6.
Grids were contrasted or stained using heavy metal stains, both lead citrate and
uranyl acetate (EMS Sciences, UK).
At present, a large number of
uranyl complexes have been synthesized due to their diversified property.

uranyl acetate & lead citrate, original magnification x 13.000.
Its use here was intended to complex the
uranyl ions in the cocktail.

abortus S19 and Brucella abortus S19[DELTA]per were negatively stained with 0.5%
uranyl acetate revealed the presence of multiple intact spherical vesicles with electron dense centre surrounded by a double membrane, though conventionally released few single membrane enclosed vesicles were also viewed.
