Mouse IgG2A Isotype Control Summary

Recognizes KLH (Keyhole Limpet Hemocyanin).  In immunohistochemistry or flow cytometry of a variety of cell types or tissues, no background staining is observed.
Monoclonal Mouse IgG2A Clone # 133304
Protein A or G purified from hybridoma culture supernatant
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.


Recommended Concentration
Negative control for flow cytometry, immunohistochemistry, or immunocytochemistry experiments. Use at the same concentration as the detection antibody.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Scientific Data

Detection of Mouse IgG Control by Flow Cytometry HT1080 human fibrosarcoma cell line was stained with Mouse Anti-Human ULBP-2/5/6 Monoclonal Antibody (Catalog # MAB1298, filled histogram) or Mouse IgG Isotype Control Antibody (Catalog # MAB0031, open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog F0101B).

Background: IgG2A

IgG is the most abundant of the five classes of mammalian immunoglobulins in serum. IgG molecules (~150 kDa) consist of two ~50 kDa heavy chains and two 25 kDa light chains connected by disulfide bonds. Antibody specificity is conferred by a combination of somatic rearrangement and hypermutation within variable regions. Mouse IgG isotypes IgG1, IgG2a and IgG2b share approximately 64-78% amino acid sequence identity within the heavy chain constant region domains (CH1, CH2 and CH3) and may vary in their interaction with complement, NK and mast cells, induction or inhibition by specific cytokines, and ability to cross the placenta.
