Polyclonals and antibodies
CD28; T-cell-specific surface glycoprotein CD28; TP44; CD28
If you buy Antibodies supplied by ELK Biotech 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 ELK Biotech. Rabbit antibodies are very stable and can be stored for several days at room temperature. ELK Biotech 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.
