Rabbit anti-goat IgG (H&L), F(ab)'2 fragment is a biotinylated secondary antibody which binds to goat IgG (H&L), F(ab)'2 fragment Antibody purity is > 90% based on SDS-PAGE. Antibody solution may contain small amounts of intact IgG.
This antibody reacts with the heavy chains on goat IgG and with the light chains on all goat immunoglobulins based on immunoelectrophoresis.Minimum cross-reactivity is observed to non-immunoglobulin goat serum proteins based on immunoelectrophoresis.Antibody is supplied in 10 mM sodium phosphate, 150 mM sodium chloride, pH 7.2, 1 % (w/v) BSA, Protease/IgG free and 0.1 % (v/v) Kathon CG is used as preservative. Use of sodium azide will inhibit enzymatic activity of horseradish peroxidase.BSA and milk have to be replaced by other blocking reagents, like doneky serum or commercial formulations which are free from bovine IgG.
Biotin conjugates can be detected by horseradish peroxidase, alkaline phosphatase substrates or anti biotin conjugated antibodies. Avidin and Streptavidin bind to the small biotin and are couple to HRP or AP for ELISA. To break the streptavidin Biotin bond we suggest to use a 6 molar guanidine HCl solution with acidity of pH 1.6.
Rabbits are used for polyclonal antibody production by agisera. Rabbit antibodies are very stable and can be stored for several days at room temperature. agisera adds sodium azide and glycerol to enhance the stability of the rabbit polyclonal antibodies. Anti-human, anti mouse antibodies to highly immunogenic selected peptide sequences are" monoclonal like" since the epitope to which they are directed is less than 35 amino acids long.
Rabbit, F(ab)'2 conjugated
Antibody fragments and scFv fragments, single chain variable fragments can be E. coli expressed. Fragment peptides for polyclonals give monoclonal like antibodies as the epitope is very small. IgG Fc and(ab)2 fragments are small and stable subunits of the antibody obtained by enzymatic digestion. Complement fragments, bp DNA fragments are common.
