Rat IgG2a isotype control and mutants (natural and engineered rtIgG2a isotype controls) are useful for functional study using animal model among a number of in vitro and in vivo re search applications including ELISA, Western Blot (WB), Flow Cytometry (Flow), Immunoprecipitation (IP), Immunohistochemistry (Paraffin) (IHC (P)), and Immunohistochemistry (Frozen) (IHC (F)). Rat IgG2a and IgG1 antibodies are more like mouse IgG1 than rat IgG2b antibodies. Most of rat antibodies are used to study mouse and human target proteins. Please contact us to ask for a quote for the engineered rat IgG2a isotype control mutants, rtIgG2a isotype control and mutants with Avi-, His-, and Flag-tags, and biotinylated rtIgG2a isotype control and mutants. A variety of conjugates (such as dyes and fluorophores) with the rat IgG2a isotype control and Fc mutants are available.

Background Rat IgG antibodies are classified to four subclasses mainly based on the isotype of the heavy chain (IgG1, IgG2a, IgG2b, and IgG2c for the heavy chain; kappa and lamda for the light chain), of which IgG1 and kappa are the most abundantnamed in serum. IgG antibodies are large molecules of about 150 kDa composed of four peptide chains, two identical heavy chains of about 50 kDa and two identical light chains of about 25 kDa. The four peptides are arranged in a Y-shape tetramer by disulfide bonds formed between the two heavy chains and between a heavy chain and a light chain. Show more
