Ultra-LEAF™ Purified Human IgG1 Isotype Ctrl Antibody

Immunoglobulin G1, or IgG1, is a type of antibody. Humans express four types of IgGs, IgG1, IgG2, IgG3, and IgG4. Antibodies in mammals are complex proteins, composed of four independent aminoacid chains. The molecule is formed by two identical heavy chains and two identical light chains. It has two binding sites, and it is produced by B cells. When the immunoglobulins are expressed in the surface of the B cell it forms the B cell receptor. Antibodies are very important players of humoral immunity and IgG1 constitutes the most abundant IgG in human blood.

Host Human IgG1, κ
Reactivity Hapten molecule not expressed in mammalian cells
Purification The Ultra-LEAF™ (Low Endotoxin, Azide-Free) antibody was purified by affinity chromatography.
Application Note The human IgG1 monoclonal antibody was produced as a recombinant protein in mycoplasma free CHO cells under serum-free conditions. This antibody reacts against a hapten that is not expressed in mammalian cells. It can be used as an isotype control when evaluating fully human, humanized, or chimeric antibodies. The human IgG1 monoclonal antibody is suitable as an isotype-matched control for ELISA, immunoblotting, FACS, IHC, and functional studies. For in vivo studies or highly sensitive assays, we recommend Ultra-LEAF™ purified antibody (Cat. 403102) with a lower endotoxin limit than standard LEAF™ purified antibodies (Endotoxin <0.01 EU/µg).
Form 0.2 µm filtered in phosphate-buffered solution, pH 7.2, containing no preservative. Endotoxin level is
Storage The antibody solution should be stored at -80°C. It can be stored under sterile conditions for one month between 2°C and 8°C, or six months at -70°C to -80°C in a manual defrost freezer. This Ultra-LEAF™ solution contains no preservative; handle under aseptic conditions.
