  This lyophilized preparation is stable at 2-8 degrees C, but should be kept at -20 degrees C for long term storage, preferably desiccated. Upon reconstitution, the preparation is most stable at -20 to -80 degrees C, and can be stored for one week at 2-8 degrees C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 degrees C to -80 degrees C. Avoid repeated freeze/thaw cycles.

• Specificity: Protein A/G/L binds to human, mouse, rat cow, goat, sheep, rabbit, guinea pig, pig, dog and cat IgG.
• Details of Functionality: Protein A/G/L is a genetically engineered protein containing 5 IgG-binding regions of protein A, 2 of protein G and 5 of Protein L. Cell wall binding region, cell membrane binding region and albumin binding region have been removed from the recombinant Protein A/G/L to ensure the maximum specific IgG binding. The recombinant Protein A/G/L is ideal for purification of polyclonal or monoclonal IgG antibodies. Protein A/G/L binds to human, mouse, rat cow, goat, sheep, rabbit, guinea pig, pig, dog and cat IgG.

Background

Protein A/G/L is a genetically engineered protein that combines the IgG binding profiles of all Protein A, Protein G and Protein L. It is a gene fusion product. Recombinant fusion protein A/G/L contains five Ig-binding regions of protein L, five IgG binding domains from Protein A, and two Ig-binding region of protein G. Cell wall binding regions, albumin binding regions and other non-specific binding regions have all been eliminated from the fusion protein to ensure the maximum specific IgG binding.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Peptides and proteins are guaranteed for 3 months from date of receipt.
