Pierce™ Anti-c-Myc Magnetic Beads (Thermo Scientific™)

Thermo Scientific Pierce Anti-c-Myc Magnetic Beads are affinity particles for immunoprecipitation of recombinant c-Myc-tagged proteins expressed in bacterial or mammalian cells or in vitro systems, using manual or robotic magnetic separators.

Features of Anti-c-Myc Magnetic Beads:

Specific—highly specific anti-c-Myc monoclonal antibody (clone 9E10) enables high yield and high purity immunoprecipitation
Convenient and fast—product instructions provide an easy-to-follow, optimized protocol for immunoprecipitation in approximately one hour
Low non-specific binding—stable, pre-blocked beads and specific antibody minimize off-target binding for c-Myc-tag IP or co-IP experiments
Versatile—beads are compatible with manual and automated workflows (e.g., Thermo Scientific KingFisher Instruments)

The blocked magnetic bead surface is coated with anti-c-Myc antibody, a highly specific mouse IgG1 monoclonal antibody (clone 9E10) that recognizes the c-Myc-epitope tag (EQKLISEEDL) derived from the human c-myc oncogene (p62 c-myc). The Pierce Anti-c-Myc Magnetic Beads can be used manually with a magnetic stand, as well as with automated platforms, such as the Thermo Scientific KingFisher Instruments, for high-throughput workflows.

Product Details:
Pierce Anti-c-Myc Magnetic Beads are convenient for the immunoprecipitation (IP) of recombinant c-Myc tagged proteins and the co-immunoprecipitation (Co-IP) of their interacting proteins. The beads are incubated with a cell lysate containing c-Myc tagged protein and the fusion protein is captured. The beads are subsequently washed and then the target proteins are eluted using 0.1M glycine (pH 2.0) 50 mM NaOH, or SDS-PAGE sample buffer, the protocol has been optimized for each of these conditions. Anti-c-Myc antibody can be used to detect c-Myc tagged protein by Western blot analysis.

Dynabeads™ His-Tag Isolation and Pulldown (Invitrogen™)

This product is designed for his-tagged protein isolation. High selectivity for poly-histidine tags results in extremely low background levels.

The new bead surface chemistry is Cobalt-based and offers exceptionally fast binding kinetics and a high yield per microliter of beads. The entire protocol (from cleared lysate to purified protein) takes only 20 minutes! The protocol includes instructions for making the required buffers as well as methods for optimizing buffer composition.

Dynabeads® His-Tag Isolation & Pulldown replaces Dynabeads® TALON™. Dynabeads® His-Tag Isolation & Pulldown has a new optimized binding chemistry that offers significant advantages over Dynabeads® TALON™ which were coated in the TALON™ chemistry. This optimization results in a cleaner prep with higher yield of his-tag protein and extremely low background levels.

Dynabeads His-Tag Isolation & Pulldown is designed for isolating His-tagged proteins from cleared lysates. Isolated his-tagged proteins can either be eluted from the beads or kept on the beads for use in bead-based downstream assays. Bead bound his-tagged proteins can be used in various downstream assays such as bait-prey pulldowns, etc.

Note: This product contains Dynabeads and a protocol only, and does not include buffers.

The technology used for the discontinued Dynabeads® TALON™ was licensed from Clontech. TALON™ is a registered trademark of Clontech Laboratories Inc., USA.

Pierce™ Anti-HA Magnetic Beads (Thermo Scientific™)

Thermo Scientific Pierce Anti-HA Magnetic Beads are affinity particles for immunoprecipitation of recombinant HA-tagged proteins expressed in bacterial or mammalian cells or in vitro systems, using manual or robotic magnetic separators.

Features of Anti-HA Magnetic Beads:

Specific—highly specific anti-HA monoclonal antibody (clone 2-2.2.14) enables high yield and high purity immunoprecipitation
Convenient and fast—product instructions provide an easy-to-follow, optimized protocol for immunoprecipitation in approximately one hour
Low non-specific binding—stable, pre-blocked beads and specific antibody minimize off-target binding for HA-tag IP or co-IP experiments
Versatile—beads are compatible with manual and automated workflows (e.g., Thermo Scientific KingFisher Instruments)

The blocked magnetic bead surface is coated with anti-HA antibody, a highly specific mouse IgG1 monoclonal antibody that recognizes the HA-epitope tag (YPYDVPDYA) derived from the human influenza hemagglutinin (HA) protein. The Pierce Anti-HA Magnetic Beads can be used manually with a magnetic stand, as well as with automated platforms, such as the Thermo Scientific KingFisher Instruments, for high-throughput workflows.

The beads are subsequently washed and then the target proteins are eluted using 0.1M glycine, pH 2.0, 50 mM NaOH, or SDS-PAGE sample buffer. If gentler elution conditions are desired, 2 mg/mL Pierce HA peptide can be used. The protocol has been optimized for each of these conditions. Anti-HA antibody can be used to detect HA-tagged protein by Western blot analysis.

HisPur™ Ni-NTA Magnetic Beads (Thermo Scientific™)

Thermo Scientific HisPur Ni-NTA Magnetic Beads are high-capacity nickel-IMAC beads for affinity purification of His-tagged fusion proteins in manual or automated formats.

Features of HisPur Ni-NTA Magnetic Beads:

High capacity—equivalent or higher binding capacity than Ni-NTA magnetic beads from other suppliers
Low nonspecific binding—the bead surface is pre-blocked and the protocol provides optimized buffers for purification
Fast—protocol is completed in 1 hour
Scalable—process microliter to milliliter sample volumes
Versatile—purify proteins using native or denaturing conditions
Reagent compatible—can be used with common cell lysis reagents and a variety of buffer additives
Multiple formats—protein coupling to the beads and downstream applications can be performed both manually and on an automated platform (e.g., Thermo Scientific KingFisher Instruments)

The blocked magnetic bead surface is derivatized with the nitrilotriacetic acid (NTA) chelation moiety and loaded with divalent nickel ions (Ni2+). The immobilized metal affinity chromatography (IMAC) beads provide high binding capacity with very low background. The HisPur Ni-NTA Magnetic Beads can be used both manually with a magnetic stand as well as with automated platforms such as the Thermo Scientific KingFisher Instruments for high-throughput needs.

HisPur Ni-NTA Magnetic Beads are used for small scale affinity purification as well as high-throughput screening of recombinant His-tagged proteins. The polyhistidine tag is the most popular affinity tag and typically consists of six consecutive histidine residues (6xHis). These tagged proteins are overexpressed in a number of different systems, most commonly in bacteria, and purified from cell lysates such as those prepared using B-PER Bacterial Protein Extraction Reagents. Purification of His-tagged proteins is achieved using a NTA chelate charged with nickel that coordinates with the histidine side chains. The NTA chelate contains four metal-binding sites which allow for low metal ion leaching and high binding capacity. The protocol for the HisPur Ni-NTA Magnetic Beads has been optimized to allow for high purity of the isolated His-tagged protein. Performance is equivalent to or better than Ni-NTA magnetic beads from other suppliers.
