All aqueous solutions were made from water purified by a Milli-Q Plus system from Millipore Corp (Bedford, MA). 2.2. pK'a values by titration Apparent dissociation constants (pK'a = −logK'a) of Gly-Tyr and Tyr-Gly were determined by potentiometric titrations. An automatic titrator ...
Calcium carbide will immediately have reaction upon coming across with water, generating acetylene and calcium hydroxide, which is the approach of industrial preparation of acetylene (carbide method), the reaction equation is: CaC2 + 2H2O = C2H2 + Ca (OH) 2. ...
GAJOE uses a genetic algorithm to select from a large pool of conformers optimized sub-ensembles that minimize the discrepancy between the experimental and calculated curves wexp according to the following equation: w2exp ¼ K 1 À 1 XK j¼1 mI À Qj Á ÀÀ IeÁxp À Qj ...
Taking advantage of the intronless structure ofELP1coding sequences, we first isolated their partial sequences fromM. pudicagenomic DNA. The genomic DNA was obtained fromM. pudicaimmature leaves using the CTAB extraction method32. Using KOD-Plus-Neo DNA polymerase (TOYOBO) and a pair of degenerat...
can both be determined independently from measurements involving the tracers we have the expression; which can be rearranged into a form that groups the similar powers of "s," the Laplace variable, in both numerator and denominator: The equation for the time-dependent behavior of oral tracer in...
as the negative control (−) and the positive control (+), respectively. Finally, the supernatant (100 µL) was aspirated into 96-well plates for analyzing the absorbance at a wavelength of 540 nm by a microplate reader. The following equation was utilized to calculate the hemolysis rate...
