New on Science Exchange: Nobel-worthy Nanosensors, MacroDSF, Fluidigm, and More

Nobel-worthy nanosensors

In 2007, Charles Lieber, the Harvard scientist who many say is in the running for a Nobel prize, co-founded Vista NanoBioSciences to enable drug discovery researchers to use his team’s nanosensor technologies for label-free, ultrasensitive detection of proteins, nucleic acids, and even single viral particles.

Vista NanoBioSensor

Now available through Science Exchange, Vista NanoBioSciences offers biomarker assays using its portable NanoBioSensor™ and BioTracker™ platforms. Vista’s NanoBioSensor precisely detects and measures biomarkers in a finger-stick drop of blood, other bodily fluid, or tissue culture – without labeling and in less than 10 minutes. Vista’s BioTracker provides continuous monitoring of dynamic changes in the targeted analytes of any biological material.  Both devices are portable, exhibiting very high sensitivity (10³ increase over ELISA), high specificity, across multiple logs of concentration, in real time.

Taking the pain out of protein purification with MacroDSF

Empowered by high-throughput protein purification and structure determination technologies, structure-based drug discovery is enjoying a resurgence.

NovAliX, a new provider on the Science Exchange network, gives you access to the ProteoPlex MacroDSF platform, an exciting tool for rapidly optimizing conditions for protein purification and crystallization.

The instrument quickly optimizes  protein concentration, pH value, salt, buffer, stabilizing additive, etc — potentially increasing a purified protein’s stability or even the resolution of its crystal structure!

NovAliX also offers a broad range of biophysical characterization services to provide a complete picture of the protein of interest.

Fluidigm custom assay development

Interested in Fluidigm’s powerful mass cytometry and microfluidics platforms, but lack the resources to design the perfect assay?

Now you can take advantage of Fluidigm’s expertise using the company’s own team of assay development scientists. Through Science Exchange, you can order custom assays for Fluidigm’s CyTOF®, Helios®, and integrated fluidic circuit-based platforms.

Oncology, from ABL1 to ZAP70

Based in Freiburg, Germany, ProQinase has been supporting oncology research for 16 years. Now on Science Exchange, ProQinase offers biochemical assay services (such as kinase screens), cellular assay services (such as proliferation, invasion and spheroid assays), and in vivo assay services (including immuno-oncology and metastasis models).

The scientific staff at ProQinase are thought leaders in oncology research. At the 2017 AACR Annual Meeting, they presented a novel assay platform to distinguish ATP-competitive from non-ATP-competitive kinase inhibitors.

Medicinal chemistry and process optimization

If you’re looking for a full-service laboratory to execute your chemistry projects, you’ll be happy to see the addition of Kalexsyn, a chemical synthesis powerhouse based in Michigan, U.S.A, to the Science Exchange network.

Whether it’s developing novel scaffolds, SAR, modification of complex natural products or challenging macrocyclic peptides, Kalexsyn’s deep bench of Ph.D. chemists provides IP-enabling expertise.

The Kalexsyn team has produced over 1000 publications and patents and has served over 85 pharmaceutical and biotechnology companies.
