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.
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.
Tissue, pathway, proteinase, peptidase, protease ,acrosin, lipoprotein, activator, caspase, trypsin, papain, esterase inhibitors are proteins or receptor ligands or receptor antagonists that bind to an enzyme receptor and decreases its activity. Since blocking an enzyme's activity can kill a pathogen or correct a metabolic imbalance, many drugs are enzyme inhibitors. Not all receptor antagonist that bind to enzymes are inhibitors; enzyme activator ligands or agonists bind to enzymes and increase their enzymatic activity, while enzyme substrates bind and are converted to products in the normal catalytic cycle of the enzyme.Human proteins from Homo sapiens human species. Homo is the human genus, which also includes Neanderthals and many other extinct species of hominids. Specific human epitopes are selected for human ELISA kits.
