NanoInk's Nano BioDiscovery division launched its Human Inflammation Cytokine Assay, the company's first completely configured protein array kit.

The fluorescence assays are based on NanoInk's Dip Pen Nanolithography platform and enable nanoscale detection of clinically relevant proteins, the company said in a statement. The assays measure a panel of 10 cytokines: IL-1alpha; IL-1beta; IL-2; IL-3; IL-4; IL-5;IL-6; IL-8; IFNgamma; and TNFalpha, and a positive and negative control.

The kit includes nanoarrays of analyte-specific antibodies and controls deposited on 1-inch by 3-inch modified glass slides. Each slide is composed of 18 sub-arrays with 48 features per array.

Assays targeting proteins implicated in other various disease states and toxicological responses are being developed for launch this year, NanoInk said.

Thermo Fisher Scientific
this week introduced its Thermo Scientific Aspire Protein A, Protein G, and IMAC Cobalt Chromatography Tips.

The proteomic tips are 1 ml pipette tips embedded with Thermo Scientific Pierce resins. Up to eight samples can be processed in parallel within 20 minutes without the need for centrifugation with the tips, the company said in a statement.
