Llama IgG2 isotype control (which consists of IgG2a, IgG2b and IgG2c isotypes) has been prepared from llama serum by multiple chromatography steps using a combination of protein A and protein G chromatography. Coomassie stained SDS-PAGE of non-reduced llama IgG2 shows a band of ~100 kDa whereas the reduced form exhibits ~46 kDa. No bands corresponding to llama IgG1 or IgG3 are observed.
