Mouse Anti-Llama IgG2 Antibody

Llama, camels, and alpacas are camelids that produce normal IgG1 like antibodies and also functional IgG isotypes that do not incorporate light chains and possess only heavy chains. These heavy-chain antibodies may constitute about 50% of the IgG in llama serum and as much as 75% of the IgG in camel serum. By virtue of their smaller size they exhibit better bio-distribution, tissue penetration, and monomeric behavior. IgG2 consists of dimers of short heavy chains, which are characterized by a normal Fc region without a CH1 domain. Although it lacks the CH1 region, it still retains an antigen binding domain called the VHH region. Clone 19D8 is shown to specifically bind to three discrete IgG2 isotypes, designated as a, b, and c, in Llama. (Ref.: Daley, LP., et al. (2005). Clin. Diag. Lab. Immunol. 12(4); 380-386).

Clone 19D8 is a mouse monoclonal antibody that detects Llama IgG2.

Purified Llama serum IgG2.

Quality Control Testing

Evaluated by Western Blotting with Llama IgG2.

Western Blotting Analysis (WB): A 1:1,000 dilution of this antibody detected Llama IgG2, but not IgG1 or IgG3.

Tested Applications

ELISA Analysis: A representative lot detected Mouse Anti-Llama IgG2 in ELISA applications (Daley, L.P., et. al. (2005). Clin Diagn Lab Immunol. 12(3):380-6; Daley-Bauer, L.P., et. al. (2010). Clin Vaccine Immunol. 17(12):2007-15).

Immunoaffinity Purification: A representative lot was used in Immunoaffinity Purification applications (Daley, L.P., et. al. (2005). Clin Diagn Lab Immunol. 12(3):380-6; Daley-Bauer, L.P., et. al. (2010). Clin Vaccine Immunol. 17(12):2007-15).

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user
