This "located" incompatibility was demonstrated by the vascular discontinuity in the graft union region that did not allow the passage of the succinic acid stain
and subsequent browning of the internal part of the wood near the graft union region (Figures 1 and 2).
Intrinsic fluorescence intensity was assigned to the eosin channel (E) while nucleic acid stains
were assigned to the hematoxylin channel (H).
From a distance it looks like a conventional acid stain
but upon closer look, one can see a shimmering and textured effect.
* Dark Brown/Black Stains: Low pH (less than 6) acid stain
. May be caused by improper detergents and soaps and/or dried-on blood.
You may recall that SYBR Green I is an asymmetrical cyanine dye used as a nucleic acid stain
in molecular biology.
(22) They also stain with Giemsa (figure 2) and Mallory's phosphotungstic acid stain
. The crystals are birefringent with polarized light (figure 3) and are readily detected with an epifluorescent microscope.
After 4 h of saliva flow, biofllms were probed with a fluorescently labeled oligonucleotide designed to target strept ococci (5'-GCTGCCTCCCGTAGGAGT-3'; JF20) as well as with a general nucleic acid stain
to detect all cells (Fig.
