Requests for tissue are evaluated on a case-by-case basis by the ALS Repository. Because there is no information pertinent to the individuals themselves and no way of tracing back samples to the patients, the use of these samples is considered to be exempt from institutional review board ...
The new assay, which is based on a suspension-array hybridization method, was tested on a series of male and female reference samples spanning the range from normal to full mutations. It was also tested on DNA from 1008 dried blood spot samples from pregnant women in their first trimester. ...
Take 10 times of the average RLU of the CC wells (B11–G11) as the cutoff value. Wells with an RLU equal to or higher than the cutoff value are considered positive. On the basis of the positive and negative rate in each dilution, calculate the TCID50according to the Reed-Muench metho...
which enables a more reliable calculation of the amounts of Lsoland Lconj. In the case that with two measurements, two parameters need to be determined (or in the case that one of the parameters, for example the polymer-water partition coefficient was determined beforehand) and thus, the deg...
Clear the activity calculation formula: Scavenging activity (%) = (1 − A1−A0A)×100% (1 − A1−A0A)×100%. A0 is the absorbance of the sample; A1 is the absorbance of the mixer of DPPH and the sample; A is the absorbance of DPPH without sample. All absorbance was ...
The soil inhibition rate was calculated as a percentage of the blank control as shown in the formula below. z = (x − y)/x × 100 (1) where z: soil inhibition rate (%), x: average value of blank root length, y: average value of root length of test soil. 2.3. Effect of ...
Additionally, the determination of the result is simple; all that needs to be compared is whether the T-line appears as a red stripe and its strength can be intuitive and accurate, and the image of the judge is simple and clear with a false negative and false positive miscalculation ...
The effects of different types of xenobiotic—a number of salts and ions of heavy metals, pesticides, quinones, and food preservatives—on the trypsin’s activity were estimated. For trypsin to be used as the basis for chemoenzymatic assays, a stable form of the enzyme should be prepared, ...
Calculation of total antioxidant capacity and polyphenolic content The molar absorptivity of Trolox® in the tested TAC methods were as follows: ε Trolox = 1.67x104 L mol-1 cm-1 (CUPRAC method); ε Trolox = 2.6x104 L mol-1 cm-1 (ABTS method); ε Trolox = 4.65x103 L mol-1 cm-...
