Target Details
Llama IgG has been prepared from llama serum by multiple chromatography steps using a combination of protein A and protein G chromatography. This product contains equal amounts of IgG1, IgG2 and IgG3. Coomassie stained SDS-PAGE of non-reduced llama IgG1 shows a band of ~150 kDa whereas the reduced form exhibits ~55 kDa (heavy chain) and ~25 kDa (light chain); non-reduced llama IgG2 shows a band of ~100 kDa whereas the reduced form exhibits ~46 kDa; non-reduced llama IgG3 shows a band of ~100 kDa whereas the reduced form exhibits ~43 kDa.
Application Details
SDS-PAGE
Llama IgG whole molecule has been tested by SDS-Page and can be utilized as a control or standard reagent in SDS, Western Blotting, flow cytometry, and ELISA experiments. Specific conditions for reactivity should be optimized by the end user. Llama IgG whole molecule buffered in 0.015 M Potassium Phosphate, 0.01125 M Sodium Chloride, pH 7.2 and 25% glycerol.

Background
Comparative studies of old world camelids (Camelus bactrianus and Camelus dromedarius) and new world camelids (Lama pacos, Lama glama and Lama vicugna) have shown that heavy-chain-only immunoglobulins represent between 35% - 70% of total IgG in the sera of all species. Such antibodies are homodimers of heavy chains that lack the CH1 domain of conventional antibodies and therefore do not interact with light chains, exhibiting a lower molecular weight ~100 kDa. In llama and all other species of camelids, these heavy-chain-only immunoglobulins belong to the IgG2 and IgG3 subclasses of gamma chain antibodies. All gamma chain camelid antibodies exhibiting the more conventional assembly of two light and two heavy chains with molecular weight ~150 kDa, belong to the IgG1 subclass.
