Manufactured
byThermoFisher |
| The
Sera-Mag range of magnetic microparticles are based on patented 1mm
magnetic carboxylate modified base particles manufactured by a core-shell
process. The surface has a unique cauliflower-like structure with a high
carboxylic acid content ensuring a high binding capacity and fast reaction
kinetics. Sera-Mag microparticles are colloidally stable in the absence of a
magnetic field, however when a magnetic force is applied the particles are
separated rapidly and completely from suspensions. |

Products
- MG-CM
Carboxylate-Modified Microparticles
The 1 mm
Sera-Mag MG-CM microparticle surface has a high carboxylic acid content
allowing simple covalent coupling of proteins, nucleic acids, etc using
standard coupling technology. Standard packaging is 15 mL, 100 mL and 1000
mL at 5% solids. These particles are ideal for colormetric assays,
heterogeneous assays, chemiluminescent assays and binding ligands of your
choice.

- MG-OL Magnetic
oligo (dT)
These 1 mm
particles contain covalently bound oligo (dT) sequences and posses a high
mRNA binding capacity (~6 mg
mRNA per mg of MG-OL depending on sample and message length). MG-OL
particles have a excellent binding stability of at least 2 years. Standard
packaging is 1 mL, 5 mL, 15 mL, 100 mL and 1000 mL at 1% solids. These
particles are ideal for RT-PCR, cDNA library construction, subtractive
hybridization and affinity purification.

Sera-Mag Magnetic
SpeedBeads Carboxylate-Modified Magnetic Particles
Thermo Scientific* Sera-Mag* SpeedBeads*
Carboxylate-Modified Magnetic Particles provide the speed, precision, and
increased binding capacity required for sample preparation, proteomics,
nucleic acid isolation and clinical immunoassay applications.
These nominal 1µm magnetic particles of
uniform size feature a second layer of magnetite, enabling them to respond
much faster to a magnetic field, resulting in quicker, more complete
separation from suspensions. This ensures shorter assay times in clinical
diagnostic tests as well as faster particle movement through viscous
solutions. Key benefits include exquisite sensitivity and low non-specific
binding for greater accuracy, and a distinct cauliflower-like surface that
increases overall binding capacity with no reduction in particle size.
Contains sodium azide.
