About this item

Thermo Scientific Pierce Fab Micro Preparation Kit uses immobilized papain protease to digest human or mouse IgG antibodies to make separate Fab and Fc fragments and subsequently to purify the Fab using Protein A agarose.

High capacity—use the micro kit for 25 to 250 µg IgG.
Enzyme-free digestion products—Immobilized Papain (beaded agarose resin) provides for control of the digestion reaction and complete removal of resulting antibody fragments from the proteolytic enzyme
Digestion and final recovery of purified Fab fragments occurs in neutral pH sodium phosphate buffer, suitable for storage or immediate use in typical applications
Spin format reduces sample processing time
Protocols are included for multiple species and IgG subclasses, as well as sample size and concentration

Suitable for human and other species of IgG. The kit procedure is optimized for human, mouse and rabbit IgG. Papain-based digestion is effective for certain other species and subclasses of IgG (e.g., goat and pig), although the purification step requires that the antibody effectively binds to Protein A.
