General description
This product is prepared by labeling high quality F(ab′)2 fragment of goat anti-rabbit IgG (H+L) with CF568. CF568 is a red fluorescent dye with an excitation spectrum optimally matching the 568 nm line of the Ar-Kr mixed-gas laser. Antibody conjugates of the dye are much brighter than those of Alexa Fluor 568. In addition, the photostability of CF568 is superior to that of Alexa Fluor 568, making CF568 a much better choice for demanding applications, such as confocal microscopy and single molecule imaging.
Specificity
Binds with whole molecule rabbit IgG and the light chains of other rabbit immunoglobulins.
Application
Anti-Rabbit IgG (H+L), F(ab′)2 fragment, CF™568 antibody produced in goat has been used in immunocytochemistry.
Biochem/physiol Actions
Immunoglobulin G (IgG) belongs to the immunoglobulin family and is a widely expressed serum antibody. It consists of a γ heavy chain in the constant (C) region. The monomeric 150kDa structure of IgG constitutes two identical heavy chains and two identical light chains with molecular weight of 50kDa and 25kDa, respectively. The primary structure of this antibody also contains disulfide bonds involved in linking the two heavy chains, linking the heavy and light chains and resides inside the chains. IgG is further subdivided into four classes namely, IgG1, IgG2, IgG3, and IgG4 with different heavy chains, named γ1, γ2, γ3, and γ4, respectively. Limited digestion using papain cleaves the antibody into three fragments, two of which are identical and contain the antigen-binding activity. They are known as fragment antigen binding (Fab) fragments. These fragments contain the light chains paired with the VH and CH1 domains of the heavy chains.
