Negative Control Magnetic Resin (covalent)

Description: Cat. #2427 Negative Control Magnetic Resin are the same magnetic beads used to produce the #2414, 2426, and 2438 mag affinity resins, but instead of attaching the corresponding affinity protein to the resin, the resin is modified to an alpha amino carboxylic acid. Use equivalent volume of the 2427 neg control mag resin as experimentally used for the 2414, 2426, or 2438 mag affinity resins as a control for non-specific binding to the resins.

Supplied as: Each vial contains 0.5mL Negative Control magnetic resin beads in approximately equivalent quantity as the 1mg/mL mag affinity resins 2414, 2426, and 2438.

Please see the Cat. #2427 Datasheet for a complete description.

Price: Cat. #2427  0.5mL/$150; 5 x 0.5mL/$600

Af1521 Macrodomain Negative Control Resin (agarose beads)

Description: Identical to the #2302 affinity resin except for two gly to asp substitutions in the macrodomain sequence, which abolishes ligand binding.  The negative control resin is useful as a control for non-specific binding.

Supplied as: 0.5mg protein/0.5mL buffer as a suspension containing ~50-75µL resin.

Please see the Cat. #2303 Datasheet for a complete description.

Price: Cat. #2303  0.5mg/$125; 5 x 0.5mg/$500

Available in a set, Cat. #4301


Af1521 Macrodomain Magnetic Affinity Resin (covalent)

Description: Cat. #2426 Af1521 Macrodomain Magnetic Resin is highly purified Af1521 macrodomain fusion protein expressed in E. coli, and covalently bound to superparamagnetic silica-based beads (resin). Typical conditions for the elution of the affinity bound proteins to the resin, for example SDS-PAGE sample buffer, will not dissociate the Af1521 macrodomain affinity protein from the resin.  The magnetic resin beads are small, with an average 1µm diameter, which remain suspended in solution for a few minutes after mixing, allowing for convenient and accurate pipetting.  Tulip Biolabs Cat. #2302 (non-magnetic) and #2305 (magnetic) macrodomain beads, above, are composed of the same affinity protein except non-covalently bound to glutathione beads.  The resin is useful for affinity purification (pulldown) of MARylated and PARylated proteins.  

See the Cat. #2427 negative control beads, below.

Supplied as: 0.5mg purified Af1521 macrodomain fusion protein covalently bound to 1µm superparamagnetic resin beads (orange dyed) in 0.5 mL buffer.

Please see the Cat. #2426 Datasheet for a complete description.

Price: Cat. #2426  0.5mg/$500; 5 x 0.5mg/$2000

Af1521 Macrodomain Magnetic Affinity Resin

Description: Cat. #2305 is the same construct as Cat. #2302, above, except here it is supplied bound to super paramagnetic glutathione beads for easier handling and higher throughput.

Supplied as: 1mg protein/1mL buffer as a suspension containing ~300µL resin.

Please see the Cat. #2305 Datasheet for a complete description and ref AZ Lu et al (2019).

Price: Cat. #2305  1mg/$625; 5 x 1mg/$2500

Af1521 Macrodomain (Poly- and Mono-ADP-ribose) Affinity Resins

The Tulip Biolabs, Inc. Af1521 Macrodomain Affinity Resins are designed for the isolation of poly-ADP-ribosylated (PARylated) and mono-ADP-ribosylated (MARylated) proteins from cultured cells and tissue lysates.

Af1521 is a thermopohilic protein from Archaeoglobus fulgidus, and contains a conserved ~190 amino acid domain known as the macrodomain.  Macrodomains are found in a wide variety of organisms including bacteria, viruses, and vertebrates.  Expressed and purified macrodomains from Af1521, Alc1, macroH2A and Bal/PARP9 proteins have been shown to bind to a subset of polymeric ADP-ribose modified proteins with high specificity and affinity.  The Af1521 macrodomain also binds to a subset of mono ADP-ribose modified proteins.  Through the use of Af1521 macrodomain affinity resins, poly-ADP-ribosylated (PARylated) and mono-ADP-ribosylated (MARylated) proteins can be isolated from cell or tissue lysates.  The resin bound proteins can be eluted from the affinity resin, and analyzed by immunoblotting, mass spec, and other methods.  Tulip Biolabs produces three types of Af1521 macrodomain beads, see below:

  Cat. #2302 GST-fusion protein bound to glut agarose beads

  Cat. #2305 GST-fusion protein bound to magnetic beads

  Cat. #2426 fusion protein covalently bound to magnetic beads


Af1521 Macrodomain Affinity Resin (agarose beads)

Description: Highly purified GST-Af1521 macrodomain fusion protein construct expressed in E. coli, and bound to glutathione agarose beads.  The Af1521 macrodomain protein binds poly- and mono-ADP-ribosylated proteins, plus free ADP-ribose.  See the Cat. #2303 negative control beads, below.

Supplied as: 1mg protein/1mL buffer as a suspension containing ~100µL resin.

Please see the Cat. #2302 Datasheet for a complete description.

Price: Cat. #2302  1mg/$450; 5 x 1mg/$1800
