General description

CF647 F(ab′)2 fragment of goat anti-mouse IgG is affinity-purified F(ab′)2 fragment of goat anti-mouse IgG labeled with a red fluorescent dye CF647, one of an outstanding series of CF dyes developed by Biotium. CF dyes are superior to both Alexa Fluor dyes and Cy dyes for antibody labeling by having combined advantages in brightness, photostability, and specificity.
Immunoglobulins (Ig) or antibodies are heterodimers of light chain and heavy chain. Ig′s are classified into five different classes according to their heavy chains types (λ, α, μ, δ, ε) namely IgG, IgA, IgM, IgD and IgE. The light chains can be either lambda (λ) or kappa chain(κ). IgG is about 150 kDa with two light chains each is about 25 kDa and two heavy chains connected in the hinge region is about 55 kDa. The light chains and heavy chains possesses variable domain (V) and constant domain (C) based on their function. IgG is further classified into two subtypes in bovidae namely IgG1, IgG2.


Binds with whole molecule mouse IgG and the light chains of other mouse immunoglobulins.


mouse IgG (H+L)


Anti-Mouse IgG (H+L), F(ab′)2 fragment, CF647 antibody produced in goat has been used in immunostaining.

Biochem/physiol Actions

Immunoglobulins (Ig) have the hypervariable antigen binding region in the N-terminal end with high affinity and specificity. IgG digestion by papain produces two fragment antigen binding (Fab) fragments and a single fragment crystallizable (Fc) fragment. The Fab fragment has complete light chain and variable and constant domain 1 (C1H) of heavy chain. The Fab fragments can bind to antigen. IgG digestion by pepsin results in one Fc fragment and a single dimeric F(ab)2 fragment. In Goat, the serum concentration of total IgG of normal adult is 19.97+1.55 mg/mL with predominant expression of IgG1. In goat, the IgG concentration is about 2.4-2.8 times greater in colostrum than in serum with IgG1 subclass accounting to 95-98%.
