A high affinity purification column was use to purify Notch 3, Antibody, Rabbit[Notch 3] by MyBioSource by chromatographic size exclusion.
1 of protein A or G purified by MyBioSource will give more specificity than crude serum.
If you buy Antibodies supplied by MyBioSource they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.
Rabbits are used for polyclonal antibody production by MyBioSource. Rabbit antibodies are very stable and can be stored for several days at room temperature. MyBioSource 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.
