Using a spectroscopy technique that monitors molecules as they traverse membranes, Wilhelm and colleagues found that crystal violet
doesn't cross the inner membrane of either cell type.
For quantitation of the CFUs formed by MSCs, crystal violet
was extracted and normalized to the number of CFUs in each sample.
After 1, 2, 3 and 4 hours of heat exposure, the least loss of MDA-MB 231 viability was measured by trypan blue meanwhile the highest was determined by crystal violet
Similar results were observed with the crystal violet
uptake in Fig.
has been shown to cause cancer in laboratory animals following long-term exposure at high levels, the FSA said.

Fetal RPE were counterstained with crystal violet
following fluorescence imaging.
Chromoendoscopy with crystal violet
detects short-segment Barrett's esophagus with greater sensitivity and specificity than does chromoendoscopy with methylene blue, based on the results of a prospective study.
After 6 days of incubation, the cells were stained with 1% crystal violet
(Sigma) in 70% methanol.
The slides were stained with crystal violet
, safranin, and gram iodine, and the bacteria were observed under a composite light microscope.
Four-micrometer-thick, formalin-fixed, paraffin-embedded tissue sections were stained with hematoxylin-eosin, periodic acid-Schiff, Giemsa, Congo red, and crystal violet
for light microscopic examination.
After water jetting, crystal violet
staining was used to quantify the amount of biofilm formation left behind, and absorbance values can be read after extraction of the crystal violet
(CV) with acetic acid.
Biofilms formed after 24 h incubation of bacterial cultures prepared as described in the previous paragraph, were stained with 20 [micro] of an aqueous solution of crystal violet
The inclusion of bile salts and crystal violet
in the medium inhibits Gram positive and non-enteric organisms, while an overlay procedure ensures anaerobic conditions, suppressing the growth of non-fermentative Gram negative bacteria.
MacConkey agar contains bile salts and crystal violet
, which inhibit the growth of Gram-positive bacteria.
