Longer oligomers

Fig. 9. The 2F4 antibodies preincubated with oligopectates of DP<9 are not inhibited and bind pectin in an ELISA test (a). Longer oligomers and PGA inhibit the Ab. N Inh control with non inhibited antibodies. Even at higher concentrations, shorter DPs do not bind the antibodies (b).

With the second pure PTA (TES) series longer oligomers with n=8, 12, 16 could be measured and the onset of the saturation covered (Fig. 26) [74]. The power law for short oligomer shows an exponent of a=2.46 0.10 in good agreement with the first pure PTA (TMS) series. The saturation is again around ten monomer units. The change from the power law to the saturated nonlinearity per number of monomers reveals to be smooth. 

When starting from chiral non-racemic mixtures of 3 7 and 4 6 L/D compositions, the short oligopeptides generated are rich in heterochiral di-astereoisomers, whereas the longer oligomers are rich with oligopeptides of... 

For our purposes, adsorption from solution is of more direct relevance than gas adsorption. Most, if not all, topics in the five volumes of FICS Involve one or more elements of it. In the present chapter, the basic elements will be introduced, restricting ourselves to low molecular weight, uncharged adsorbates and solid surfaces. Adsorption of charged species leads to the formation of electrical double layers, which will be treated in chapter 3. Adsorption at fluld/fluid Interfaces follows in Volume III. Adsorption of macromolecules will be Introduced in chapter 5. Between monomers, short oligomers, longer oligomers and polymers there is no sharp transition in the present chapter we shall go as far as non-ionic surfactants, but omit most of the association and micelle formation features, which will be addressed in a later Volume. There will be some emphasis on aqueous systems.
