Thermo Fisher Scientific, AnaSpec, Agilent Technologies, and Waters

Thermo Fisher Scientific this week launched the Pierce SILAC Protein Quantitation kit for the identification, characterization, and quantitation of proteins. The kits allow for isotopic labeling of the proteome for the analysis of relative abundance by mass spectrometry. The kit includes Thermo Scientific HyClone media, heavy and light amino acids, and HyClone dialyzed serum.

AnaSpec released 13 new peptides for drug discovery research last week. They include Helodermin; Angiotensin II receptor, AT2; Amino terminal fragment; and Doc-6 (130-145). The company also introduced this week a line of insulin receptor antibodies.

Agilent Technologies said last week it is offering Agilent Intelligent Services on its 1200 Series LC systems, its installed base of 1100 Series LC systems, and single quadrupole mass spectrometry systems.
Agilent Intelligent Services provides Internet-based, remote instrument monitoring and systems diagnostics. It has been available since March 2007 as a standard set of features within the company’s support agreements, Agilent said in a statement.


Waters launched this week the VanGuard Pre-Columns, designed to protect UPLC columns from chemical and particulate contamination. In a statement Waters said the Pre-Columns are the first guard columns for routine use at pressures up to 15,000 psi and in applications run on the Acquity UPLC system.
