Goat Anti-Rabbit IgG （H+L）, F（ab'）2 Fragment is a type of secondary antibody fragment that is widely utilized in various immunological assays due to its specific characteristics. Derived from immunoglobulins of goats that have been immunized against rabbit IgG, this fragment consists of the antigen-binding regions （Fab'）2 of the antibody molecule, which includes both the heavy （H） and light （L） chains. The F（ab'）2 fragment is obtained by enzymatic digestion of the whole IgG molecule, specifically using pepsin, which cleaves the molecule into pieces while retaining the antigen-binding sites.
