FabRICATOR-HPLC

FabRICATOR®-HPLC

FabRICATOR-HPLC is an HPLC column for fast on-column digestion of monoclonal antibodies.

The cysteine protease FabRICATOR (IdeS) immobilized on the column delivers rapid and consistent subunit generation, perfect for automated online analysis in a middle-level LC/MS workflow.

Detailed Information

The FabRICATOR-HPLC column 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 FabRICATOR-HPLC column is designed as an analytical tool for rapid on-column digestion in middle-level workflows for characterization of antibodies and Fc-fusion proteins. After digestion, the fragments can be analysed using reversed phase HPLC, mass spectrometry or other analytical method. Automation of antibody digestion and subunit generation enables applications in online monitoring of bioreactors, for example as part of a 2D-LC-MS setup, coupling the reactor directly the MS. This automated approach to antibody subunit analysis reduces operator time, sample handling and increases the throughput.

In-house performance testing* of the FabRICATOR-HPLC column highlights the stability and reproducibility, for complete data see here. The column delivered consistent digestion for 14 days at 37°C. More than 450 injections of mAb were made during testing and no carry-over was observed. Reproducible Fc glycan profile analysis was obtained showing the column to be suitable for online process monitoring. Modified Fc glycans on a therapeutic mAb were also detected using FabRICATOR-HPLC fragmentation followed by LC-MS.

* Tested with trastuzumab in PBS, injections every 40 minutes, at a flow rate of 25 µl/min, samples collected, reduced and analyzed by RP-HPLC.

Storage

Store the column at +4-8°C in 10 mM sodium phosphate, 140 mM NaCl, pH 7.4 when not in use. 
Store the column with the endcaps in place, carefully sealed to prevent drying. 
For long-term storage of the column 0.02% (w/v) sodium azide can be added as a preservative.

Performance  

The performance of the FabRICATOR-HPLC column at 37°C is typically >200 injections with a digestion efficiency of >95% for 10 µg human IgG1 (1 mg/ml) sample in PBS, pH 7.4.
