FragIT Z

FragIT Z

The FragIT Z spin columns contain FabRICATOR Z (IdeZ) enzyme covalently coupled to agarose beads, for digestion of mouse IgG2a and IgG3 without contaminating the final preparation with enzyme.

FabRICATOR Z is a cysteine protease that digests mouse IgG2a and IgG3 at a specific site below the hinge, generating a homogenous pool of F(ab')2 and Fc fragments after 2 hours incubation.

Detailed Information

FragIT Z consists of FabRICATOR Z enzyme immobilized on agarose beads in a convenient spin column format. The spin columns are available for digestion of up to 0.5 mg (Microspin) mouse IgG2a and IgG3 in three different pack sizes, with 2, 5 or 10 columns per pack.

FabRICATOR Z digests mouse IgG2a and IgG3 at a specific site below the hinge region, producing a homogenous pool of F(ab')2 and Fc fragments. Most mouse IgG2a are digested by FabRICATOR Z within 2 hours although the enzyme:ab ratio and/or digestion time may need to be optimized for certain antibodies. There is no risk of overdigestion if the incubation time is prolonged. Since FabRICATOR Z digests IgG under physiological reaction conditions, the immunoreactivity is preserved.

Storage and Stability

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

Unit Definition

One spin column contains sufficient FabRICATOR Z-coupled agarose beads to digest 0.5 mg mouse IgG2a or IgG3.

Popular FAQ

We can only guarantee optimal digestion for one-time use. We do not have a cleaning or regeneration protocol to provide. However, depending on the antibody and the following application the column can be reused. We do not recommend using with different antibodies due to the risk for contamination of carry-over from previous sample. If column reuse is desired store the column in 10-20% ethanol at +4-8°C.
