FabRICATOR MagIC employs magnetic beads for fast automated processing of up to 96 antibodies in parallel.

The popular cysteine protease FabRICATOR (IdeS) immobilized on magnetic agarose beads delivers rapid and consistent subunit generation for multiple antibodies in parallel, perfect for fast automated analysis of CQAs in a middle-level LC/MS workflow.

Detailed Information

The FabRICATOR MagIC magnetic beads with immobilized FabRICATOR (IdeS) enzyme digests IgG rapidly and specifically just below the hinge, generating F(ab’)2 and Fc fragments without any risk of over-digestion. The beads enable fast automated digestion of multiple antibodies in parallel in a middle-level characterisation workflow. They are designed for automation platforms like the Thermo Scientific™ KingFisher™ Duo Prime Purification System but perform equally on a shaking table if automation is not available. After digestion, the samples can be directly transferred to the autosampler of the LC-MS for fast chromatography or to another analytical method for analysis. Automated parallel antibody digestion and subunit generation allow for the processing of the numerous samples associated with clone selection, process development and stability studies for a potential biopharmaceutical. Automated antibody subunit analysis reduces operator time, risk for sample handling errors and increases the throughput.

FAQ and Support

Popular FAQ

FabRICATOR MagIC is suitable for using in automated systems that can handle magnetic beads. On the applications page you can read about how it’s used in a KingFisher™ workflow.

The FabRICATOR MagIC magnetic beads with immobilized FabRICATOR (IdeS) enzyme.

The protocol for FabRICATOR MagIC is based on using standard PBS pH 7.4 as digestion buffer. FabRICATOR in solution is compatible with most commonly used buffers at pH=6-8 and the same buffers should work for FabRICATOR MagIC, but the incubation time might need to be optimized.

FabRICATOR is a cysteine protease. It should not result in any other modifications than the digestion of the peptide bond. Digestion will be between the two Glycines (…CPAPELLG / GPSVF…) and the C-terminus will regain the carboxyl group – that is addition of one OH-group and the N-terminal amino group will be regained (addition of one H).

In summary, R1-CO-NH-R2 + H2O –> R1-COOH + NH2-R2.
