Subclass

All of the varieties within a given type of security. For example, subclasses of a stock include mid-cap, small cap, high cap, growth and value stocks, among others. While all securities are most similar to others of the same type, discussing subclasses is useful to describe the differences in expense, risk, expected rate of return, and other factors within a certain type.

Subclass.

Each asset class -- stock, bonds, and cash equivalents, for example -- is made up of a number of different groups of investments called subclasses.

Each member of a subclass shares distinctive qualities with other members of the subclass.

For example, some of the subclasses of the asset class bonds are US Treasury bonds, mortgage-backed agency bonds, corporate bonds, and high-yield bonds.

Similarly, some of the subclasses of stock are large-, medium-, and small-company stock, blue chip stock, growth stock, value stock, and income stock.

Because different subclasses of an asset class perform differently, carry different risks, and may go up and down in value at different times, you may be able to increase your return and offset certain risks by diversifying your portfolio, which means holding individual securities within a variety of subclasses within each asset class.

Several anti-human IgG MAbs with specificity for Fc region-dependent epitopes common to three of four human IgG subclasses have been produced in the present study.
One group of our MAbs (n=4) was shown to be specific for isotypic epitopes common to IgG1, 2, 4, but not IgG3 subclasses.
Three of our anti IgG1, 2, 4 MAbs (1F5A8, 6F11E1 and 8F9G7), recognize conformational epitopes located to heavy chain of IgG1, 2, 4 but not IgG3 subclasses and a protein of IgG3 subclass (Goe protein) (Figure 1), a reactivity pattern similar to SPA (21).
The only amino acid which is common between Goe protein and IgG1, 2 and 4 subclasses and is different between Goe protein and other IgG3 molecules, is histidine at position 435.
Since three of our MAbs (1F5A8, 6F11E1 and 8F9G7) displayed similar binding activity to SPA with regard to interaction with purified human myeloma proteins of IgG1, 2 and 4 and the IgG3 myeloma protein Goe, as well as human polyclonal IgG1, 2 and 4, but not IgG3 subclasses (Figure 1), the specificity of these MAbs resembled that of SPA.
The fourth MAb (6F19C11) in this category is completely different from the others as it does not recognize any protein of IgG3 subclass and it recognizes a linear epitope located to IgGl, 2, 4 subclasses (Figure 3).
The second group of our MAbs (three MAbs) was shown to be specific for isotypic epitopes common to IgG 1, 2, 3, but not IgG4 subclasses (Figure 2).
IG14 and IG15 recognize conformational epitope (s) located to Fc region of IgG1, 2, 3 subclasses (25).
