MagStrep "type3" XT beads
Magnetic Strep-tag® purification at its best!
A superior tool for small scale purifications with high demands on protein purity.
MagStrep “type3” XT beads are Strep-Tactin®XT coated ferri-magnetic spheres with the following characteristics:
- high binding capacity (1 – 3 nmol/μl beads, corresponding to 30 – 90 μg of a 30 kDa protein)
- very low non-specific protein binding due to improved coating
- flexible elution conditions, under denaturing conditions by boiling in SDS gel loading buffer or under
native conditions with biotin
- high affinity for Strep-tag® – due to new Strep-Tactin®XT
These characteristics lead to very good purification results and make the MagStrep “type3” XT beads a superior tool for small scale purifications with high demands on protein purity.
Satisfied customers will get an additional vial of 2 ml magnetic beads for free if they share their data with us. Unsatisfied customers will get their money back.
For native elution a specific elution buffer is required - Buffer BXT - biotin elution buffer (2-1041-250). This buffer has a higher biotin concentration than our buffer BE and enables a more efficient elution from the "type3" XT beads. Desthiobiotin cannot be used for elution from MagStrep "type3" XT beads.
