PurKine™ His-Tag Ni-NTA Resin
Application notes: PurKine™ His-Tag Ni-NTA Resin effectively purifies high levels of overexpressed His-tagged fusion proteins in gravity column procedures at a variety of scales. The Resin consists of 90μm beads of highly cross-linked 4% agarose, to which Nitilotriacetic acid (NTA) has been coupled. The chelating group has then been charged with nickel ions (Ni2+). Tests confirm that performance equals or exceeds popular Ni-NTA resins from other suppliers, and no decrease in performance occurs after at least five repeated uses.
Formulation: Liquid solution with 50% slurry in 20% ethanol.
Storage buffer: Liquid in PBS buffer containing 20% ethanol.
Storage instructions: Stable for one year at 2-8°C from date of shipment. Do not freeze.
Shipping: Blue ice

Background: PurKine™ His-Tag Purification system is based on innovative high-capacity IMAC matrix for convenient single-step purification of His-tag proteins from total lysates. Our propriety ion-chelate chemistry ensures extraordinary compatibility with commonly used reducing agents such as DTT, chelating metalloprotease inhibitors such as EDTA, and a wide range of buffer substances and salt conditions. The portfolio provides wide choice of chelating group (IDA, NTA or Super NTA), cross-linked agarose (crosslinked 4% or 6% agarose), ions (Nick, Colbat, Copper, or non ion charged) and compatible ingredients to allow optimization of process for maximum protein yield, stability and solubility. Tests also confirm that no decrease in performance occurs after at least five repeated uses. The PurKine™ His-Tag Purification resin is also available as prepacked spin column and kit formats.
