Strep-Tactin® gravity flow columns

Prepacked chromatography columns for gravity flow purification of Strep-tag fusion proteins are availble with different resin supports:

Strep-Tactin^® Sepharose^®
Strep-Tactin^® Superflow^® high capacity

They are provided in different sizes (0.2 ml; 1 ml; 5 ml and 10 ml).

When to use which resin?

Sepharose^®	Economic alternative to Superflow^® Agarose support with good flow properties For gravity flow chromatography only (not pressure stable)
Superflow^®	Our all-rounder and the resin to start with for large proteins and protein:protein interaction analysis Agarose support with low unspecific binding properties For increased flow rates Low pressure stable (FPLC/HPLC/Äkta applications) Only available as 50% suspension - not available as ready-to-use gravity flow column
Superflow^® high capacity (HC)	The capacity of Superflow^® is not sufficient or the binding affinity to Twin-/Strep-tag^® fusion proteins need to be slightly improved! 3-5 fold higher binding capacity as Superflow®
MacroPrep^®	The alternative if Sepharose^® and Superflow^® lead to non-specific binding of protein (e.g. Chlorophyll from plant extracts) Synthetic support with low non-specific binding properties Highly pressure stable (FPLC/HPLC /Äkta applications) Only available as 50% suspension - not available as ready-to-use gravity flow column

Strep-Tactin® Purification Buffer Set	1 Set	2-1002-001	USD 90.00	Quantity:
Strep-Tactin® Purification Buffer Set is a convenient buffer set for the purification of recombinant Strep-tag®II and Twin-Strep-tag®II fusion proteins on immobilized Strep-Tactin® and its regeneration. ... Further details, manuals, data sheets, related products and more
10x Buffer R; Strep-Tactin® Regeneration Buffer with HABA;	100 ml	2-1002-100	USD 52.00	Quantity:
Buffer R is a Strep-Tactin® Regeneration Buffer with HABA for the regeneration of immobilized Strep-Tactin®. HABA (2-[4 -hydroxy-benzeneazo]benzoic acid) displaces desthiobiotin (present in Buffer E: Strep-Tactin® Elution Buffer with Desthiobiotin) at the biotin-binding site of Strep-Tactin®. The yellow HABA solution turns red upon binding to Strep-Tactin® clearly indicating the regeneration process and activity status of the column. ...
