Protein Targets for XA Selections

Protein target quality and purity significantly affect X-Aptamer selections.  AM Biotech works with experts in the research protein industry to provide high quality proteins that are well suited for use as X-Aptamer selection targets.

All of the proteins in our catalog are sourced from vendors that demonstrate a commitment to delivering excellent quality.  We are confident that protein targets purchased from our catalog will perform well in X-Aptamer selections.

We strive to ship proteins within 1 to 2 weeks; however, many proteins do not store well for more than 6 months.   To ensure the best quality, if a protein is ordered infrequently, then shipment may take 4 to 6 weeks.  After receiving an order for an infrequently purchased protein, the cells are recovered from storage and expanded.  The protein is expressed, purified, and then checked for quality prior to shipment.  This ensures that you receive the highest quality protein.

Our biologically active proteins are manufactured and validated to the highest standards.  Each recombinant bioactive protein has been tested in a suitable assay using appropriate cell lines, proteins or reagents to test the activity of the protein.

Our recombinant proteins are available in several different expression systems, including E.coli, Yeast and mammal.  Most recombinant proteins can be ordered in a variety of tagged and non-tagged forms.
