"If it isn't certified, how do you know?" Two years ago, the issue of ice purity was unexpectedly brought into focus when a Florida seventh grader, Jasmine Roberts, made national headlines for a science project that compared the purity of water from ice machines to that from the toilets in a variety of fast-food restaurants.
For the 89 patients, we compared the purity and total DNA yield (μg) from blood and saliva samples.
The French critic Jacques Lourcelles, perhaps Matarazzo's most articulate champion, compares the "lyrical purity" of Matarazzo's images to "the most successful works of Lang, Dreyer and Mizoguchi".
Quality control was carried out comparing the radiochemical purity of [99mTc(CO)3]+ in the three kit formulations used.
Analogously, if the number of instances in one cluster is under the minimum threshold value v, this cluster can be merged into other clusters by comparing the cluster purity.
The main focus of this work is to compare the radiochemical yields (RCYs), radiochemical purities (RCPs), enantiomeric excess (ee), synthesis times, reliability, and a potential for automation of the different radiosynthesis pathways.
One measure of potential efficacy of our system is demonstrated by comparing the CD34+ cell purity achieved using P-selectin with that of cell-capture surfaces comprised of an antibody against a stem cell surface marker directly.
Following each protocol, we compared the RNA amount and purity and the amplification success as evaluated by standard PCR and real-time PCR.
We compared the DNA yield and purity across a wide range of flowering plants among PMC, the silica-based DNeasy Plant Mini kit (QIAGEN, Dusseldorf, Germany), and a CTAB-based method (adapted from Doyle and Doyle, 1987).
