Most of the labeled antibodies used to date in immunoradiometric assays have been eluted at pH 2.0. In a few cases the recovery of antibodies has been measured and may be as high as 80%. Certain losses are inevitable and even desirable. Damage will occur due to iodine, radiation, and oxidation, and it is the aim of the procedure selectively to discard these along with antibodies of lower affinity. Although further radioactive material can be eluted by the reduction of pH below 2, such material has never been satisfactory for assays in the authors hands. It is not certain whether this represents antibodies of still higher affinity that have been irreversibly damaged by the extreme pH or small amounts of tightly adsorbed nonspecific protein or even breakdown of the immunoadsorbent itself. Naturally, because the immunoadsorbent is itself protein it is impossible to eliminate iodination of this protein. 

Solid PDA have not had an extensive reaction chemistry largely due to their van der Watds tight-packed structures which effectively preclude diffusion of potentially reactive liquids and gases (. Recently (17), reactions of poly-DCH (2c) with electrophiles have led to modified materials which are homogeneous on microscopic examination. The reactions are anisotropic. Bromination resulted in a crystal-to-crystal transformation, while chlorination and nitration have led to amorphous solids to date. The scope of such reactivity is clearly of interest. 

In today s apparel industry, fashion products require a significant amount of customization due to differences in body measurements, diverse style preferences and replacement cycles. Apparel manufacturers are usually given a short production lead-time, tight delivery dates and small quantities with frequent style changes. To cope with the increasing demand for product customization, the quantity of garments per production order tends to be smaller and thus the number of production orders is higher. 

To date, penetrant diffusion throu polymers has been studied by MD only in amorphous polymers. This is mainly due to the commonly held belief that only very few penetrants can enter the tightly packed crystallites and that those which do, get trapped at defect locations and hardly move afterwards. Therefore, diftusivities in the crystallites should be orders of magnitude smaller than those in amorphous regions and diffusion in a senu-crystalline material should be dominated by its amorphous part, even if it is small. In addition, if diffusion is excessively slow, one is unlikely to observe it on the time scale accessible to MD (i.e., ns).
