Most of the research monoclonal antibodies are obtained from mice. These animals have a rich repertoire of immunoglobulins (Ig), displaying various isotypes (IgA, IgD, IgG, IgE, and IgM). Mouse IgGs can be categorized into five subclasses IgG1, IgG2a/c, IgG2b, IgG2c, and IgG3. In addition to these subclasses, each IgG molecule can be equipped with either a lambda or kappa light chain. The most striking difference between mouse IgG2 to other subclasses of IgGs is the significantly shorter hinge region (~12 amino acids shorter).

sdAb anti-Mouse IgG2a/b binds specifically and strongly to mouse IgG2a and IgG2b independently of the IgGs VH (lambda or kappa light chain) domain.

Formulation:

DBCO- and Biotin-conjugated sdAbs (1:1 labeling on the C-terminus) are lyophilized from PBS pH 7.4. Unconjugated sdAbs are lyophilized from 5 mM KPi pH 6.0, 300 mM NaCl, 0.5 mM EDTA pH 6.0. Reconstitute with 250 µL pure deionized water for immediate use or with 250 µL sterile 50% glycerol for storage at -80°C. The HRP-conjugated sdAbs are lyophilized from HRP protector buffer and should be reconstituted with 200 µL pure deionized water for storage at 4°C or with 200 µL high purity, sterile 50% glycerol for storage at -80°C.
