transillumination

A method of examination in which a bright light is shone through tissue to try to determine whether it contains abnormal structures such as a solid tumour.

Transillumination

A technique of checking for tooth decay by shining a light behind the patient's teeth. Decayed areas show up as spots or shadows.

transillumination 

1. The shining of light through a translucent membrane. This is principally used to better visualize ocular tumours, cysts or haemorrhages within the eye. It is accomplished by directing a narrow intense beam of light on the side of the eye. Example: If a tumour is present in the eye some light will not be reflected and the pupil will appear partially or completely black, instead of bright red as when the healthy eye is thus illuminated. Syn. transcleral illumination.
2. See retro- illumination.

Agarose 2%, and TBE (1X) at (75 V/cm for 90 min., stained with Ethydium bromide dye and visualized on a UV transilluminator. Lane(L): DNA ladder (100-3000 bp), Lanes: (1-12) stool samples.
The amplification band was observed under UV Transilluminator and detection of resistance gene was done with the use of marker.
(b) In 1.5% agarose gel electrophoresis, the products of reverse transcriptase-polymerase chain reaction for conditions above were revealed with ethidium bromide in a transilluminator. M: molecular marker; C-: amplification negative control ([H.sub.2O); C+: DNA obtained from macrophages stimulated with 5 [micro]g/mL of lipopolysaccharide (LPS); MO: macrophages (negative control, uninfected and untreated); Cb: macrophages treated with C.
Agarose gel was dyed with "RedGel" (in the concentration indicated by the manufacturer) in order to make the amplified products visible in the ultraviolet transilluminator (Espectroline-UV).
After amplification reaction the product was resolved on agarose gel and visualized under a UV transilluminator. All the variables being categorical were analyzed through count and percentages.
Neotech Products is excited to announce the release of their newest product, the NeoGlo[TM] Transilluminator. The NeoGlo Transilluminator is a light source that transmits light through tissues to aid in the examination of patients.
UV Transilluminator (BIOTOP Transilluminator, TU1002, China) was used to visualize genomic DNA and PCR products.
For instance, regardless of its reasonable color change stability ([greater than or equal to]2 weeks), when employing ethidium bromide, a UV transilluminator must be available; both of them are toxic, resulting in deleterious consequences on human health and the environment (25-30).
After electrophoresis the gel was visualized on UV transilluminator and was photographed under UV light on gel documentation system (BioRad Corporation, USA).
RNA integrity was analysed by running the samples on a 1% agarose gel stained with GelRed[TM] (Biotium, Hayward, CA, USA) and visualised using an ultraviolet (UV) transilluminator.
Several lines of evidence suggest, however, that the retention of the tourniquet for more than one to two minutes is a significant cause of haemoconcentration, which may also spuriously increase the concentration of several analytes (36,37), but which can be avoided by using transilluminator devices (38).
This, combined with an integral slide-out UV transilluminator, and optional blue epi-illumination module and white light table, make the system suitable for documentation and analysis of almost all fluorescent and colorimetric gels.
