HisCube HisCube Ni-Indigo His-Tag Protein Purification MINI Kit
Supplier: CUBE BIOTECH
The HisCube His-tag protein purification MINI kit is our way to supply your laboratory with a convenient method for high-quality, small-scale His-tag protein purifications. We put all of our experience in His-tag purifications into this Kit to provide a protocol that is easy to follow.

Magnet strength: Above average. To ensure no magnetic beads get lost during the separation process
Area covered on work bench: 3 cm² per module
Cap holder: Included, so that microcentrifuge tubes do not fall close if not wanted
Color: White
The HisCube Ni-INDIGO MINI kit contains our in-house developed PureCube 100 Ni-INDIGO agarose resin and our PureCube 1-Step batch MINI batch spin tubes.
INDIGO's most significant advantage is its tolerance towards reducing and chelating agents. These can be used to great help in His-tag purifications, but traditional His-tag affinity beads do not tolerate them. EDTA is a chelator often used in eukaryotic cell buffers because it has protease-inhibiting functions. DTT can dissolve protein aggregates that could hinder the access of the purification beads to the His-tagged proteins. However, thanks to INDIGO, both substances can be used now. Therefore, they are part of the kit.
