Antibody fragments and scFv fragments, single chain variable fragments can be E. coli expressed. Fragment peptides for polyclonals give monoclonal like antibodies as the epitope is very small. IgG Fc and(ab)2 fragments are small and stable subunits of the antibody obtained by enzymatic digestion. Complement fragments, bp DNA fragments are common.
Storage, shipping and handling
The antibody is shipped at +4 degrees Celsius. Upon receving, freeze at -20. For longer periods of time we recommend keeping the vial frozen at -40 or -80. Avoid cycles of freezing and thawing as they may denaturate the polypeptide chains of the antibody. Due to transportation or handling reasons, small amounts of the antibody might get caught on the lid or walls of the vial. We recommend you to briefly cetrifuge the vial prior to use to gather the content on the bottom.
