Agilent Technologies has introduced a microfraction collection system for single or multidimensional chromatographic separation of complex peptide and protein mixtures. The system is based on Agilent’s 1100 Series liquid chromatography system. Priced at $100,000, it is available for ordering now and will be shipped starting in August.

Agilent also published a method for characterizing soybean quality using protein profiles generated using the Agilent 2100 Bioanalyzer with the Protein 200 Plus LabChip kit. The application note is available free of charge from the Agilent website at www.agilent.com/chem.

 

Gyros has introduced a new CD microlaboratory called Gyrolab MALDI IMAC for the preparation of phosphorylated peptides for MALDI mass spectrometry. Protein digests are prepared in duplicate, and phosphorylated peptides are concentrated, purified, and crystallized directly onto MALDI target areas on the CD. One of the duplicate samples is dephosphorylated prior to crystallization. The CD allows the preparation of up to 96 samples in parallel.

Biacore International has launched two sensor chips and upgraded software for its Biacore S51 system. Sensor chip SA enables the immobilization of biotin-labeled proteins, while sensor chip L1 allows users to immobilize lipids and liposomes.

The new software, version 1.2, is free of charge for current users of Biacore S51 and will be the standard for all new systems.

 

Ciphergen Biosystems has launched an Interaction Discovery Mapping platform, which uses purified and identified protein biomarkers as “bait” on Ciphergen’s coated chips or affinity beads. These Trap-eZe beads are preactivated and covalently bind bait molecules or antibodies.

 

Eksigent Technologies will be launching its NanoLC Proteomics System at next week’s ASMS conference. The company claims this is the first HPLC instrument that allows nanoscale LC/MS without flow splitting. It includes a binary gradient pump, autosampler, injection valve, control software, and separation columns. Initial deliveries are scheduled for July.
