Contains covalently attached oligo(dT)25 to directly bind mRNA.

20-50nm particles

Analyze wide size range materials through laser diffraction or other methods with uniform polymer particles that mimic real world particles.

Improve sensitivity and detectability for analytical methods with microsphere suspensions that are internally dyed and feature bright, high-contrast colors.

Conveniently check the sizes of bacteria, viruses, ribosomes and sub-cellular components with these size standards.

Meet the need for particulate materials with a variety of particle sizes and properties with Thermo Scientific™ 5000 Series Polymer Particle Suspensions

Simplify the preparation of calibration wafers with these particle size standards.

Excellent for coupling oligos or proteins directly to beads. Their “cauliflower-like” structure gives Sera-Mag beads high binding capacity. The carboxyl groups on these single shell magnetite beads can be activated by standard EDC/EDAC chemistry to react with free amino groups, forming amide bonds.

Improve sensitivity and detectability for analytical methods with fluorescent particles that feature bright, distinct colors.

Ensure accurate and convenient calibration of laser particle counters with Thermo Scientific™ 3K/4K Series Particle Counter Standards.

Save time when measuring analytes with Thermo Scientific™ Cyto-Plex™ Carboxylated Particles, open platform particles for suspension array analysis.

Use Thermo Scientific™ Dri-Cal™ Particle Size Standards for calibrating particle sizing and counting instruments that require dry particles.

Minimize contamination by eliminating the need for serial dilutions and extensive sample handling with Thermo Scientific™ COUNT-CAL™ Count Precision Standards.

Optimize research in light scattering, microporous filter checking, and aerosol particle generation with these particle suspensions.

Achieve high visual contrast with polymer particles that are internally and deeply dyed in intense red or black.

Improve sensitivity and detectability for analytical methods with green aqueous fluorescent particles.

Meet the need for particulate materials with a variety of particle sizes and properties with Thermo Scientific™ 7000 Series Copolymer Microsphere Suspensions.

Achieve improved sensitivity and detectability in analytical methods with internally dyed microspheres that feature bright, high-contrast colors.

Achieve maximum reactivity in many diagnostic applications with Thermo Scientific™ OptiBind™ Polystyrene Sulfate Particles.

Minimize response of analytic systems to shape effects with monosized particles.

Obtain superior test sensitivity in qualitative and quantitative lateral flow tests with Thermo Scientific™ Color-Rich Dyed Carboxylate-Modified Particles.

Control sensitivity, specificity and stability with various acid content available within Thermo Scientific™ OptiLink™ Carboxylate-Modified Particles.

Replace polystyrene spheres in many applications with dry glass NIST™-traceable size standards.

Achieve high visual contrast with Thermo Scientific™ ChromoSphere™-T Certified Size Standards, colored polymer microspheres with NIST™-traceable diameters.

Provide a fast, convenient method for manual and automated magnetic isolation of IgA and IgG proteins using affinity binding. The beads can be used with the broadest range of antibody species and subclasses (even when subclass identity has not been determined).

Lower detection limits of fluorescent assays by limiting background interference from relatively short-lived matrix fluorescence.

Excellent for coupling oligos or proteins directly to the beads. Their “cauliflower-like” structure gives Sera-Mag beads high binding capacity. The carboxyl groups on these beads can be activated by standard EDC/EDAC chemistry to react with free amino groups, forming amide bonds.
