Isotype or positive controls by peptides, antibodies and deactivated samples.
Immunoglobulin gamma, IgG, mouse monoclonal H&L chain clones or rabbit, goat polyclonal antibodies have 4 parts. There are 2 heavy chains, 2 light chains. The IgG antibody has 2 antigen binding sites. They represent 70% or more of serum antibodies. This antibody can be antigen purified or protein A or G purified. For storage sodium azide is added or you can call us to request azide free antibody preparations. These will need colder storage temperatures. Polyclonals can be used for Western blot, immunohistochemistry on frozen slices or parrafin fixed tissues. The advantage is that there are more epitopes available in a polyclonal antiserum to detect the proteins than in monoclonal sera. Rabbits are used for polyclonal antibody production by immunostep. Rabbit antibodies are very stable and can be stored for several days at room temperature. immunostep 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.
Immunoglobulin Isotype specific antibodies and controls are specific to the immunoglobulin heavy chains and immunoglobulin light chains. Mouse monoclonal antibodies from this clone have all the same affinity to the antigen. Also polyclonal antibodies are Isotype purified amd conjugated or if they are used as control non conjugated.
