Example sentences for: tester

How can you use “tester” in a sentence? Here are some example sentences to help you improve your vocabulary:

After DNA reassociation, the ratio of bb' /aa' increases from 2 to 4. If expression of another gene is down-regulated 3 times in the tester, the formula is (3a + b) (3a' + b') = 9aa' + bb' + 3a'b + 3ab'.
With direct labeling, Cy3-dCTP is incorporated into control and Cy5-dCTP into tester DNA during the PCR amplification of the hybridized DNA templates.
The reverse subtraction was carried out with the control sample as tester to isolate fragments corresponding to genes whose expression level decreased following the treatment.
The CT primer amplifies the control DNA (aa') exponentially and hybrid DNA (a'b and ab') linearly while the TT primer amplifies the tester DNA (bb') exponentially and hybrid DNA linearly since hybrid DNA has two different adapters at the ends.
The subtractive hybridization was performed by adding 1.5 μl driver cDNA to each tube, one containing 1.5 μl of adaptor 1 and the other containing 1.5 μl adapter 2R-ligated tester cDNA (tester cDNA was approximately 30 times less concentrated than driver cDNA) in 1 μl 4X hybridization buffer.
