On the contrary, fd-ME is adopted to avoid matrix effects by determining the total amount of the analyte in the samples, and performed by using very low ratio of sample to extraction phase or extraction phase with extremely large distribution coefficients for analytes.
Here, using low molar ratios (1 1 to 1 100) of the two linkers resulted in loss of binding capability of the anti-EGFR (epidermal growth factor receptor) antibody nimotuzumab, as assessed by surface plasmon resonance imaging.
While the stability of PS films is systematically improved upon addition of the highly substituted copolymers, using the copolymer with relatively low ratio of ClMS group could lead to the opposite result.
The major drawback of all systems using reactive coatings is their low ratio of hydrogen mass generated to support structure mass.
The authors now have taken advantage of their very extensive characterization of yeast vacuolar fusion and show that fusion requires lipids with small head groups (which favor stalk formation) when using low protein-to-lipid ratios (on the order of 1 5000 or 1 9000).
Using low doses, 0.03 % enzyme-to-substrate ratio, of the enzymes pectin lyase and polygalacturonase in combination with potato pulp, a low-value industrial by-product, we show that high molecular weight galacto-rhamnogalacturonan can be solubilized in the stomach of weaning piglets.
With a combination of increasingly stringent regulations, like energy codes for new buildings, as well as other conservation programs and rising prices, Chinese planners hope to preserve a similar low ratio of energy use to growth in the decade to come, Mr. Zhou said.
Predictors of prolonged mechanical ventilation were low ratio of PaO2/FiO2, high static compliance and inotropic use at baseline.
Experts say a lucky combination of factors may for the moment have slowed the arrival of an epidemic, including a low ratio of customers to sex workers, low rates of certain other sexually transmitted diseases and limited intravenous drug use.
With its low ratio of water to flour, bagel dough generally is considered low-hydration.
