FragIT Z - Immobilized FabRICATOR Z

FragIT Z is FabRICATOR Z (IdeZ) enzyme immobilized on agarose allowing for antibody subunit fragmentation without contaminating the final preparation with FabRICATOR Z enzyme. The agarose is supplied in spin columns for digestion of mouse IgG2a or IgG3 antibody.

With the FragIT Z Kit it is possible to go one step further to purify the F(ab')2 from the Fc fragments. The kit consist of two spin column, one with FragIT Z resin and the other with CaptureSelect™- an agarose matrix with a 13 kDa lama antibody fragment recognizing Fc of multiple species with high affinity.

FragIT Z Kit

FragIT Z kit is an extremely rapid and easy way of creating and isolating F(ab')2 and Fc fragments from mouse IgG2a and mouse IgG3. The kit consist of two spin columns - one for fragmentation (FragIT Z column) and one for purification of F(ab')2 and isolation of Fc fragments.

The FragITZ column is FabRICATOR Z enzyme immobilized on agarose and the second column has affinity ligands selective for Fc fragments.

Detailed Information

FragIT Z is a resin with FabRICATOR Z (IdeZ) enzyme covalently coupled to agarose beads for subunit fragmentation of mouse IgG2a and IgG3 to generate pure F(ab’)2 and Fc fragments without contaminating the final preparation with enzyme. IgG is simply incubated with the FragIT Z resin and fragments are then easily collected by a centrifugation step.

FragIT Z cleaves mouse IgG2a at one specific site below the hinge region and thereby eliminating the risk of over digestion if the incubation time is increased.

FragIT Z digests mouse IgG2a under physiological reaction conditions thus preserving the immunoreactivity. Digestion is performed at room temperature but if needed digestion can be preformed at 37°C.

Stability

FragIT Z is supplied in 20% ethanol, shipped on ice and should be stored at +4-8°C upon arrival. Do not freeze the product!

It is possible to reuse the column for digestion of the same antibody but we can only guarantee optimal digestion for one time use. We do not recommend to use the same column for different antibodies due to the risk of carry over. If desired to reuse the column store in 20% ethanol at +4-8°C.

Buffers

FragIT Z can be used with all commonly used buffers with pH ranging from 6.0 to 8.0. Optimization may be required. Note that the FabRICATOR Z enzyme is irreversibly inactivated below pH 5.0.

CaptureSelect™ Column

The CaptureSelect columns contains multi species Fc affinity matrix and is an agarose bead with a 13 kDa lama antibody fragment recognizing IgG of multiple species with high affinity. The used ligand is directed towards domains on the Fc part of IgG that enable purification of IgG of, amongst others, human, mouse, bovine, rabbit, rat, goat, horse, and sheep.

CaptureSelect is supplied in 20% ethanol, shipped on ice and should be stored at +4-8°C. Do not freeze the product.

CaptureSelect columns are only sold together with the FragIT Z columns as part of a kit and are not available as a stand alone products.

Enzyme Reference Tool

FabRICATOR is used frequently for studying important quality attributes of antibody-based biotherapeutics. To help you find the reference of interest we developed an Enzyme Reference Tool that organizes all papers published using our products. With this tool you can filter by quality attribute, enzyme used, type of antibody molecule and technology.

FAQ and Support

Latest FAQ

FabRICATOR® cleave the IgG molecule in one specific site in the lower hinge region of the anitbody leaving a F(ab')2 fragment and a Fc-fragment.

You can indeed elute the Fc fragments from the CaptureSelect column using a low pH buffer commonly used for example during protein A/G purification of antibodies. We have successfully used 0.1 M glycine buffer pH 2.6-2.8 to release the Fc fragments. Be sure to adjust pH back to normal using a 1 M Tris-HCl buffer or similar directly after isolation of the Fc fragments from the CaptureSelect column.

To use protein A or MabSelect Sure (GE) for removal of Fc as a platform after digestion with FabRICATOR or FragIT is problematic. Therefore we have chosen CaptureSelect in the FragIT Kit for removal of Fc fragments. CaptureSelect is much more specific for Fc. Both protein A and MabSelect Sure (GE) may have affinity for Fab and the degree of affinity is antibody dependent.

We have many customer reports on this subject and they usually comes back to us for the CaptureSelect columns for the above reason.
