Affinity Purification Products & Reviews

1 row of 8 columns, 600 µl, RoboColumn unit prepacked with UNOsphere SUPrA affinity chromatography resin

Streptavidin isolated from Streptomyces avidinii covalently bound to agarose.

The Affinity protein expression and purification system provides a simple, gentle and effective method for high-level protein expression and purification. The complete system includes pCAL expression vectors containing a calmodulin-binding peptide tag and calmodulin affinity resin.

StrataClean resin eliminates the need to perform phenol:chloroform extractions, which are highly toxic and combustible. The resin is a non-toxic, non-combustible slurry of hydroxylated silica particles that is used to clean up DNA or concentrate dilute protein mixtures.

QuickPick™ GST kit for proteins, 48 preps (62411)The ready-to-use QuickPick GST glutathione affinity kit is intended for the purification of GST (glutathione-S-transferase)-tagged proteins. It is optimized for use with the PickPen 1-M magnetic tool, and at least 40 ug tagged protein can be purified per prep.

The InterPlay Mammalian TAP System allows you to recover interacting proteins from mammalian cells. This method is based on expression of a protein of interest fused to two affinity tags: a streptavidin binding peptide (SBP) and a calmodulin binding peptide (CBP).

The Affinity protein expression and purification system provides a simple, gentle, and effective method for high-level protein expression and purification. A complete Affinity protein expression and purification system includes calmodulin (calcium-modulated protein or CaM) affinity resin and pCAL expression vectors, containing a calmodulin-binding peptide (CBP) tag.

Introducing an all-in-one centrifugal device for the protein purification workflow.Traditional protein purification is a long process with many steps and multiple devices, often resulting in protein degradation and loss. Avoid the risks associated with sample transfer and reduce hands-on time when you bind, wash, elute and/or concentrate your protein in the all-in-one Amicon® Pro purification system. No matter what your workfl…

FG beads are magnetic nanoparticles, suitable for various applications. There are many kinds, which have different functional groups and pre-immobilized proteins.

FG beads® are beads approximately 0.2 μm in diameter that are composed of multiple ferrite particles coated with a special polymer called poly-GMA (glycidyl methacrylate). The FG beads® that are manufactured using this original technology are used as matrices for affinity purification and provide characteristics that are superior to conventional matrices.
