Many promoters have been isolated that differ in cell-type specificity, size and strength.
Stout, JE, Belknap, R, Wu, Y-J, and Ho, CS. "Paradox of serial interferon-gamma release assays: variability width more important than specificity size". The International Journal of Tuberculosis and Lung Disease : the Official Journal of the International Union Against Tuberculosis and Lung Disease 22, no. 5 (May 2018): 518-523.
The specificity and size of the dihydroorotate pool size change suggest a role for the Rid family in pyrimidine synthesis, possibly in countering an adverse effect of carbamoyl phosphate (or its breakdown product isocyanate) on dihydroorotate dehydrogenase.
For specificity, the size (>60 bp) of the tags is long enough to be identified as the corresponding gene and the frequency of each tag numbered provides an accurate measurement of its expression level.
These studies will address key questions about sensitivity, specificity, the size of tumors that can be accurately detected, the mechanisms underlying the observed changes in volatile profiles, the ability to generalize among different types of lung cancers, and the impact of current or former smoking.
This observed variance between datasets emerges either from actual differences in transcription factor binding (GABP binding in a more distributed manner), from variation in the preparation of samples (such as differences in antibody specificity or size selection during the preparation of the sequencing library) or a combination of such factors.
Reactions were run out in the 7500 Real Time PCR System (Applied Biosystems) with the following conditions: 1 cycle of 95°C for 15 min, 35 40 cycles of 94°C for 30 s, 55°C for 30 s, 72°C for 50 s, 1 cycle of 72°C for 5 min. The resulting amplicons were checked for specificity and size in agarose gels.
For dose, test sensitivity, test specificity, sample size, etc., need to be taken into account.
This gives us sets of potentially nested functional modules that range in specificity and size.
In addition, the PCR products were validated by checking the specificity and size on 1% agarose gel.
To confirm amplicon specificity and size, a melting curve analysis was performed and the final QPCR products were migrated on a 2% agarose gel for each primer set.
