Plateau values for

Capture ELISA on selected oligomeric fractions of formalin-treated RNase A (see curves 3-7 in Fig. 15.9) also reveal that the plateau values increase with an increase in the number of cross-linked molecules in the fractions. This is due to an increasing proportion of bound epitopes per binding site or, in other words, epitope density on the surface. Thus, the nearly identical plateau values for the titration of native RNase A and formalin-treated unfractionated RNase A (curves 1 and 2 in Fig. 15.9) are fortuitous, being caused by the particular composition of oligomers present in the formalin-treated RNase A preparations that was analyzed. [Pg.267]

The value for k will normally decrease as the concentration of the solution decreases but the value for A will increase because of the increased dissociation of molecules in dilute solutions. A value for the molar conductance at infinite dilution (A,)) can be determined by plotting the calculated values for A against the molar concentration of the solution used and determining the plateau value for A. From such investigations it is possible to determine the ionic mobilities of ions (Table 4.3) and calculate the molar conductance of an... [Pg.182]

The binding kinetics were characterized in terms of the apparent time constant (K pp = kf C + k ) where C = analyte concentration kf = association rate constant and k = dissociation rate constant. In closed loop experiments, a plateau value for K pp of 0.0024/s was reached at a linear flow rate of 2.67 mL/min. K ppWas foxmd to decrease with decreasing antigen concentration (C), with equilibrium achieved only at the highest level (1 pg/mL). The association rate constant Kf was calculated at 3.6 x 10 M/s for IgG binding. [Pg.195]

The temperature dependence of the line widths in Figure 12.11 can be explained by the difference in Tg of the iPP matrix and of the elastomer EP the lowest temperature in Figure 12.11 is above the Tg of EP, but below the Tg of iPP. Neglecting the relative small variations in line width of Xe in EP and by referring to Figure 12.3 for PMMA, one can state that for EP for all temperatures the line width has reached the low plateau value for polymers at temperatures above Tg, while for the iPP matrix the line width shows exactly the same behaviour as for PMMA in Figure 12.3. [Pg.470]

The non-ionic surfactant gives higher adsorbed amounts at the same concentration than the anionic surfactants. This is especially valid at low concentrations, whereas at very high concentrations both surfactants reach the same plateau value. For a hydrophilic solid surface this effect can be just the opposite due to a higher affinity of anionic surfactant to the surface via specific interactions. [Pg.52]

On the contrary the plateau values for the two copolymers are very different. Since the higher copolymer gives thicker films a surface force component of steric origin may be evoked. However, the thickness hK is an effective parameter which is too crude. As a reasonable compromise between physical relevance and tractability, the three-layer model is adopted. Within the three-layer model the foam film is viewed as a symmetric sandwich structure [159] two adsorption layers symmetrically confine an aqueous core (Fig. 3.34). [Pg.154]

As shown in Eqs. (3-19) and (3-20), the singlet and triplet radical pair of one nuclear state oscillate between them. If there are many nuclear states, their oscillations interfere with one another and the S-T oscillation cannot be observed as shown in Fig. 6-3(b). Brocklehurst measured the scintillation pulse shape (7) for solutions of / ira-terphenyl and obtained the following interesting MFEs (7 = 7(0.16 T)/7(0 T) ) as shown in Fig. 6-4(a) [30] (1) For terphenyl-/ i4 and terphenyl-c/n in delaline, each of their R(t) values increases after the peak of a scintillation pulse and then attain the maximum value. After the maximum, each of their R(f) values decreases and then attain a plateau. (2) Although the plateau values for terphenyl-hu and terphenyl-di4 are the same, the time profiles of their R t) values before the plateau are quite different fi om each other. This is due to the smaller HFC constants of terphenyl-<7i4 than those of terphenyl-Tin. This is a typical example of MIE of D. [Pg.88]

As far as we know the tetrahedral niobate group occurs only in the fergusonite structure of YNbO4 which is a distorted version of the scheelite structure of CaMo04 This luminescence is bright blue and has a relatively high Tq, viz. 500 jfg decay time is 15 MS at 11 which is short in comparison with the plateau value for the molybdate tetrahedron. It is very unfortunate that no more data exist on this complex with its efficient luminescence. [Pg.25]

Approximate plateau values for the interfacial tension y are 3, 10, and 20 mN-ur1 for the nonionic, caseinate, and PVA, respectively. [Pg.443]

Our hypothesis that GMP is a particle network was confirmed by re-disper-sion and re-aggregation experiments. Clear differences between particles could be observed. These differences are possibly related to difference in HMWGS composition and help explain differences in G plateau values for GMP. [Pg.96]

The surface density/solution concentration isotherms, not shown in this paper, reflect also the differences in the behavior of mucin and collagen upon their adsorption at solid interfaces. While the collagen isotherms on polyethylene and surface-grafted polyethylene show a plateau of adsorption at solution concentrations higher than 0.05 mg/ml, no plateau values for mucin adsorption are observed on polyethylene and surface oxidized polyethylene. [Pg.461]

When the cyclic dimers reach their plateau value (x 1), the total monomer (meta + para) concentration is well above the critical concentration. Under this condition, p andp , coincide with the initial mole fractions of the two monomers (equal to 0.5), because the distribution of monomeric units within the linear fraction is always purely statistical, and when the total monomer concentration is well above the CC, the statistical linear fraction overwhelms the nonstatistical contribution of the cyclic fraction. Since the EM values of 12 and 14 (EM21 = 13.4 mM and EM23 = 0.30 mM) were known from previous one-monomer DL experiments (see Section 4.1.3), we can expect that the plateau values for the concentrations of homodimers 12 and 14 are J4 of their EM values, that is, 3.35 mM and 0.075 mM, respectively. The plateau value for concentration of homodimer 12 in the two-monomer system was indeed found to be 3.2 mM which is very close to the estimated value, whereas that of the homodimer 14 was too low to be detected, again in accordance with the estimated low value. Saturation value for the equilibrium concentration of heterodimer 13 was 11.4 mM which corresponds to EM22 = 11.4/0.5 = 22.8 mM. It should be stressed... [Pg.38]

Results of calculations for the relaxation rates v are shown by the empty circles in Fig. 8 as a function of 1/n [10]. Unlike the predictions of the Rouse model, a linear dependence between the relaxation rates and the size of the kinetic unit is observed. The filled circles are from the BD simulations of Fixman [99,100] for a polyethylene-like chain. Dependence of Vkk on the mode number for a 16 bond polyethylene chain are shown by the empty circles in Fig. 9. The filled circles are from the BD simulations of Fixman [99, 100] for a similar chain. The curve is the best fitting curve through the empty circles. It is interesting to note that both the DRIS approach and Fixman s simulations yield a plateau value for the rate of most of the relaxational modes, while a few slowest modes exhibit distinct lower values. [Pg.178]
