 (sī′ə-nēn′, -nĭn)
Any of various blue dyes, used to sensitize photographic emulsions to a greater range of light.


(ˈsaɪəˌniːn) or


1. (Dyeing) a blue dye used to extend the sensitivity of photographic emulsions to colours other than blue and ultraviolet
2. (Dyeing) any of a class of chemically related dyes, used for the same purpose


(ˈsaɪ əˌnin, -nɪn)

also cy•a•nin


any of several groups of dyes that make silver halide photographic plates sensitive to a wider color range.

Having said this, an unexplained phenomenon was evident in columns 5-10 of both the Cy5 and Cy3 blocks for all the slides used in which a gradual decrease in signal from column to column was evident in the columns under surveillance.
In the laboratory, each sample is labeled using red Cy5 and green Cy3 dyes.
On array 1 and array 3, the exercised muscles were incorporated with Cy3 dye, and on array 2 and array 4, exercised muscles were incorporated with Cy5 dye.
The lymphocyte population was indentified using anti-CD45 monoclonal antibody conjugated to Cy5 and integrated to establish the NK cell population using dual staining with anti-CD56 and CD16 monoclonal antibody conjugated to phycoerythrin (Beckman Coulter; Paris, France).

Briefly, fluorescent RNA targets were prepared from 5 [micro]g of total RNA samples using the MessageAmp[TM] aRNA kit (Ambion, Austin, TX, USA) and Cy5 dye (Amersham Pharmacia, Piscataway, NJ, USA).
This technique involved pre-labeling two protein extracts, using two fluorescent cyanine dyes known as Cy3 and Cy5.
Right) Images illustrate protein spots fluorescently labeled with Cy2, Cy3, or Cy5.
EarlyTox Live Red Dye is detected by using Cy5 channel (Ex622/Em645 wavelength); EarlyTox Dead Green Dye is detected by using FITC channel (Ex503/Em526nm) wavelength.
The amplified HPV L1 gene and human beta actin gene were labeled with Cy5 and hybridized with an HPV DNA chip (GG HPV DNA Genotyping Chip Kit, GoodGene Inc, Seoul, Korea) that simultaneously detects 47 HPV genotypes.
Thus, the treatments were: control (non-amended sandy soil), CT (sandy soil+compost only), CT5 (sandy soil+a mixture of compost and 5% the fine-textured soil), CT20 (sandy soil + a mixture of compost and 20% the fine-textured soil), CY5 (sandy soil +5% fine-textured soil alone), CY20 (sandy soil + 20% fine-textured soil alone).
The control cDNA sample labeled with Cy5 and the treated sample cDNA labeled with Cy3 were combined and hybridized on the first microarray.
