Anti-Rabbit IgG (H+L), highly cross-adsorbed, CF^™750 antibody produced in donkey

Immunoglobulin G (IgG) is a glycoproteins that binds to specific antigen with high affinity. The antigen binding site of immunoglobulins is formed by six hypervariable regions, three in the V_L domain in the light chain and three in the V_H domain in the heavy chain.

Binds all rabbit IgGs (minimal cross-reaction with bovine, chicken, goat, guinea pig, hamster, horse, human, mouse, rat and sheep serum proteins)

Anti-Rabbit IgG (H+L), highly cross-adsorbed, CF^™750 antibody produced in donkey, is a secondary antibody developed against both heavy and light chains of rabbit immunoglobulin G (IgG). IgG is a larger molecule with a molecular weight of 150 kDa. IgG has two light chains (L) and two heavy chains (H). The light chain can be either lamba (λ) or kappa (κ) chain. Functionally, immunoglobulins have constant region and variable region. Light chain has one variable region in the N-terminal V_L and followed by one constant domain C_L. The light chain is approximately about 25 kDa. The heavy chain has one variable region in the N-terminal and followed by three constant domains. In between the first (C₁H) and second constant (C₂H) domain is a spacer hinge region, which connects both the heavy chains. Each heavy chain is about 55 kDa.

This product is prepared by labeling highly cross-adsorbed donkey anti-rabbit IgG (H+L) with the near-IR fluorescent dye CF750, one of an outstanding series of CF dyes developed by Biotium. To minimize cross-reactivity, the antibody has been adsorbed against Bovine, Chicken, Goat, Guinea Pig, Syrian Hamster, Horse, Human, Mouse, Rat, and Sheep serum. Our CF750-labeled antibodies are suitable for flow cytometry with 633 nm excitation. Although the absorption peak of the conjugate is at 755 nm, excitation at 633 or 635 nm still yields excellent fluorescence. In fact, our CF750 antibody conjugates are brighter and more specific than antibodies labeled with APC-Alexa Fluor 750 tandem dye. CF750 is one of our three near-IR CF dyes. It is superior to other similar near-IR dyes, such as Alexa Fluor 750, IRDye and the DyLight near-IR dye. All of our near-IR CF dyes have combined advantages in brightness, photostability, specificity and novel features ideal for in vivo imaging, near-IR Western blotting and flow cytometry
