Immunoglobulins properties, table

Factor VIII, immunoglobulin, and albumin are all held as protein precipitates, the first as cryoprecipitate and the others as the Cohn fractions FI + II + III (or FII + III) and FIV + V (or FV), respectively (Table 7, Fig. 2). Similarly, Fractions FIVj + FIV can provide an intermediate product for the preparation of antithrombin III and a-1-proteinase inhibitor. This abiUty to reduce plasma to a number of compact, stable, intermediate products, together with the bacteriacidal properties of cold-ethanol, are the principal reasons these methods are stiU used industrially.

Because the basic concepts of immunity are now so well known, no attempt is made to deal with these here. For reference, however, the interrelationships between the main cells involved in immune processes are shown in Fig. 11.1 and the properties of the various immunoglobulins are summarised in Table 11.1. For more extensive coverage of theoretical and practical principles of immunology, reference should be made to recent texts or reviews, some of which are listed below.

Table 3.1 lists the classes and subclasses of human immunoglobulins and presents some of their properties. No subclasses of IgM are indicated in the table since reports of the presence of two subclasses have not been well substantiated. We will consider first some of the properties common to all the classes and make some comparisons among them.
