anti-IgG2 (human), Rabbit Monoclonal (RM118) (Biotin)

IgG (Immunoglobulin G) is the most abundant Ig isotype in serum and makes up approximately 75% of all serum Immunoglobulins. In humans, there are four subclasses of IgG with highest serum concentrations of IgG1 followed by IgG2, IgG3 and IgG4. The IgG molecule consists of two heavy and two lights chains (κ or λ) resulting in a molecule with two arms for antigen binding. High levels of IgG antibodies are induced following the initial IgM response in a typical immune response to antigens. Because of its relative abundance and excellent specificity toward antigens, IgG is the principle antibody used in immunological research and clinical diagnostics. Clinically, measured IgG antibody levels are generally considered to be indicative of an individual's immune status to particular pathogens. This anti-human secondary antibody has well-characterized specificity for human IgG2 immunoglobulins and is useful in the detection, sorting or purification of its specified target. In general, secondary antibodies offer increased versatility enabling users to use many detection systems (e.g. HRP, AP, fluorescence). They can also provide greater sensitivity through signal amplification as multiple secondary antibodies can bind to a single primary antibody.
