In this article, all values (except the ones listed below) denote blood plasma concentration, which is approximately 60–100% larger than the actual blood concentration if the amount inside red blood cells (RBCs) is negligible. The precise factor depends on hematocrit as well as amount inside RBCs.
The ratio of the absorbance at 260 and 280 nm (A 260/280) is used to assess the purity of nucleic acids. For pure DNA, A 260/280 is widely considered ~1.8 but has been argued to translate - due to numeric errors in the original Warburg paper - into a mix of 60% protein and 40% DNA. [6] The ratio for pure RNA A 260/280 is ~2.0. These ratios are ...
The ratio of NADP +:NADPH is maintained at around 1:50. [7] This allows NADPH to be used to reduce organic molecules NAD + + H + + 2e − → NADH: −0.320 −0.280 The ratio of NAD +:NADH is maintained at around 30:1. [7] This allows NAD + to be used to oxidise organic molecules FAD + 2 H + + 2 e − → FADH 2 (coenzyme bonded to ...
The standard definition of a reference range for a particular measurement is defined as the interval between which 95% of values of a reference population fall into, in such a way that 2.5% of the time a value will be less than the lower limit of this interval, and 2.5% of the time it will be larger than the upper limit of this interval, whatever the distribution of these values.
In rat liver, the total amount of NAD + and NADH is approximately 1 μmole per gram of wet weight, about 10 times the concentration of NADP + and NADPH in the same cells. [17] The actual concentration of NAD + in cell cytosol is harder to measure, with recent estimates in animal cells ranging around 0.3 mM , [ 18 ] [ 19 ] and approximately 1.0 ...
Biosensors used for screening combinatorial DNA libraries. In a biosensor, the bioreceptor is designed to interact with the specific analyte of interest to produce an effect measurable by the transducer. High selectivity for the analyte among a matrix of other chemical or biological components is a key requirement of the bioreceptor.
Heather Locklear Calls Out the Differences Between “Spin City” Costars Michael J. Fox and Charlie Sheen
In statistical process control (SPC), the ¯ and R chart is a type of scheme, popularly known as control chart, used to monitor the mean and range of a normally distributed variables simultaneously, when samples are collected at regular intervals from a business or industrial process. [1]
