Isotype control antibodies are negative controls used to measure non-specific binding or background levels of a primary antibody in different cell types. They are not specific to any target in a cell, yet retain all non-specific characteristics of the antibodies they control.
This is purified native rabbit sera and as such there was no immunogen.
Aliquot the rabbit antibody and store frozen at -20oC or colder to avoid repeated freeze-thaw cycles.
If you buy Antibodies supplied by NJS poly they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.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.
Isotype or positive controls by peptides, antibodies and deactivated samples.
isotypes,Polyclonals and antibodies
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 NJS poly. Rabbit antibodies are very stable and can be stored for several days at room temperature. NJS poly 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.
