Anti-mouse IgG2a mAb (MG2a), unconjugated

Product specifications

Intended use

This monoclonal antibody enables specific detection of mouse IgG2a in immunoassays such as ELISpot and ELISA.

Serum/Plasma samples

Recommendation

MG2a is recommended as detection mAb in ELISpot in combination with capture mAbs MT24/JC5-1 (product code 3876-3) or with coated antigen. The antibody is also suitable for antigen-specific ELISA.

Analyte information

IgG2a

Analyte description	Immunoglobulin G (IgG) is the most abundant Ig isotype in serum, making up approximately 80% of all serum Immunoglobulins. In mice, the IgG subclasses are defined IgG1, IgG2a/c, IgG2b, and IgG3. The IgG2a allele is expressed in e.g., Balb/c mice.
Alternative names	Immunoglobulin G2a, IgG2a, 1810060O09Rik, Igh-1, Igh-1a
Cell type	B cell
