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 other species of camelids, these heavy-chain-only immunoglobulins belong to the IgG2 and IgG3 subclasses. 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.

Specifications for Llama IgG1 isotype control Fluorescein

Product Details

Description: Llama IgG1 Isotype Control Fluorescein Conjugated - 025-0240

Synonyms: Llama IgG1 isotype, Llama IgG1 subclass isotype, Llama IgG1 Fluorescein Conjugated, Llama IgG1 FITC, Llama isotype control

Species of Origin: Llama

Conjugate: Fluorescein (FITC)

Format: IgG1

Type: Native Protein

Target Details

Purity/Specificity: Llama IgG1 isotype control 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 unconjugated llama IgG1 shows a band of ~150 kDa whereas the reduced form exhibits ~55 kDa (heavy chain) and ~25 kDa (light chain). No bands corresponding to unconjugated llama IgG2 or IgG3 are observed. Fluorescein Conjugated Llama IgG1 was proven by Dot Blot.

Application Details

Application Note: Llama IgG1 FITC Conjugated isotype control can be utilized as a control or standard reagent in Flow Cytometry, immunofluorescence microscopy, fluorescence based plate assays (FLISA) and fluorescent western blotting experiments where determination of sample isotype is important.
