Polyclonals and antibodies
If you buy Antibodies supplied by BT-Laboratory they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.
Chemokines, chemokine receptors, ligands , motif chemokines and cytokines are supplied by BT-Laboratory in 1.FAS ligand and other ligands are binding to the receptor for signaling pathways for example in apoptosis or JNK signaling. Receptor agonists are often tested for drug development.
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 BT-Laboratory. Rabbit antibodies are very stable and can be stored for several days at room temperature. BT-Laboratory 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.
