High-Performance Immunoprecipitation at an Affordable Price

 :: Posted by American Biotechnologist on 08-12-2014

Bio-Rad Laboratories, Inc. announced that it has launched its SureBeads Magnetic Bead System, which provides researchers with a faster and easier alternative to agarose beads for immunoprecipitation for as low as half the price of other available magnetic bead systems. Benefits include reduced antibody consumption and sample loss, very low nonspecific binding, and optimized IgG binding capacity.

Researchers have traditionally used agarose beads to precipitate and enrich proteins prior to western blotting or mass spectrometry. This process is time-consuming and labor-intensive, and often causes the beads to perform poorly. Since agarose beads are porous, the antibody can remain trapped inside the bead and therefore is unable to properly bind the protein of interest, requiring researchers to use more antibody.

Although magnetic beads are often more expensive, they are an attractive alternative to agarose beads for several reasons, including ease of use at the bench: magnetization is faster and more convenient than centrifugation for sample precipitation and washing steps. With the launch of the SureBeads System, scientists now have access to a high-performance, cost-effective magnetic bead system.

SureBeads Protein A and G Conjugated Magnetic Beads are designed to work with the proprietary SureBeads 16-Tube Magnetic Rack, which offers a one-piece removable magnetic strip to improve sample handling and eliminate repeated centrifugation steps, so researchers are able to achieve results up to six times faster.

“I have used magnetic bead–based systems for more than three years now, and the quality of the new SureBeads System is among the best in the field,” said Oliver Wueseke, PhD student at the Max Planck Institute for Molecular Cell Biology and Genetics in Dresden, Germany. “The real innovation resides in the rack. The slidable magnet, preferred fixation of tubes in the rack, and spacing between tubes that allows easy access to the tube lids make the SureBeads System easy to handle, faster, and more convenient.“

Overcoming PCR Inhibitors

Sso advanced universal inhibitorBio-Rad Laboratories announced the launch of the SsoAdvanced™ Universal Inhibitor-Tolerant SYBR® Green Supermix, a proven solution for obtaining reproducible, optimal-quality qPCR data from the most challenging samples.

Generating quality qPCR data from difficult-to-amplify samples such as crude lysates from plants, tissues, formalin-fixed paraffin-embedded samples, and other less-than-ideal sources that contain PCR inhibitors can be challenging and frustrating. In these situations, PCR may be greatly inhibited, making it nearly impossible for researchers to obtain reliable data, wasting time and money.

The formulation of the SsoAdvanced™ Universal Inhibitor-Tolerant SYBR® Green Supermix has been optimized and validated to tolerate a wider spectrum of PCR inhibitors than competing SYBR® Green reagents. These inhibitors include those found in crude lysates, polysaccharides and polyphenols, and various reagents left over from sample prep such as ethanol, isopropanol, EDTA, and sodium chloride see performance data for all inhibitors.

As with all SsoAdvanced Supermixes, the inhibitor-tolerant version includes Bio-Rad’s Sso7d-fusion polymerase, which is engineered for enhanced qPCR performance. The supermix is compatible with all real-time PCR instruments and functions under any reaction condition.

Sorting With Safety

 :: Posted by American Biotechnologist on 07-07-2014

s3-biosafety-system-class-IBio-Rad Laboratories, Inc. announced the launch of its S3™ Biosafety System Class I, an intelligent aerosol containment hood designed for Bio-Rad’s S3™ Cell Sorter. The system adheres to the biosafety requirements of the International Society for Advancement of Cytometry (ISAC) and protects users and the environment from aerosols created during the cell sorting process.

The S3 Biosafety System Class I encloses the S3 Cell Sorter on the benchtop, providing an alternative to the large and expensive biosafety hoods traditionally used with cell sorters.

Additional benefits of the S3 Biosafety System Class I include:

  • Software control — integrates with Bio-Rad’s S3™ ProSort™ Software, which provides real-time information about biosafety system status, system temperature, and HEPA filter life
  • Fully accessible — offers easy access to the S3 Cell Sorter for cleaning and maintenance via vinyl walls that are magnetically attached to the aluminum biosafety system frame
  • Quiet and energy efficient — generates low vibration and sound levels while specialized fans and low backpressure from the HEPA filter reduce energy usage

A Robust Method for Detecting DNA Methylation

 :: Posted by American Biotechnologist on 06-09-2014

DNA methylation is one of the most studied epigenetic modifications. DNA methylation plays an important role in a number of physiological processes as well as common diseases such as cancer and neurodegenerative disorders. Recent data have shown a correlation of DNA methylation and disease status. However, there is an unmet need for a sensitive yet robust method to analyze DNA methylation in clinical samples.

In the bulletin “Droplet Digital PCR: Detection of DNA Methylation”, Bio-Rad Laboratories demonstrates teh unprecedented sensitivity, linearity and robustness of DNA methylation detection by ddPCR in a model system for an imprinted gene involved in neurological disorders.
