Varian, Chemicon International, RefSeq release 1, Imaging Research, Select Biosciences


Varian of Palo Alto, Calif., now offers its Omix pipette tips for peptide extractions on a microliter scale. The pipette tips contain a monolithic sorbent, which, according to the company, allows researchers to isolate up to about 40 percent more peptide with an improved standard deviation. Also, the technology improves flow and binding capacity, according to the company.

Temecula, Calif.-based Chemicon International, a division of Serologicals, has introduced a number of tissue microarrays for studying proteins implicated in cancer. The company offers a series of 30 human and animal tissue arrays derived from normal and cancerous formalin-fixed and paraffin-embedded tissues. The arrays come in three formats: high density, with 180 1 mm tissue spots per slide; low-density, with 60 2 mm spots per slide, and trial size, with 10-20 2 mm spots per slide. They are designed for both high-throughput auto-mated and manual screening.

RefSeq release 1, the first full release of all NCBI RefSeq records, is now available by anonymous FTP at: The release incorporates genomic, transcript, and protein data available as of June 30 and has over 785,000 proteins and sequences from 2005 different organisms.

Imaging Research of St. Catharines, Canada, a subsidiary of Amersham Biosciences, has released version 7.0 revision 1.0 of its MCID Elite image analysis software. New features include co-localization for fluorescence microscopy, three new curve types for ELISA binding, and four point logistic and Michaelis-Menten for densitometry calibrations.

Select Biosciences of Acton, UK, has published a market report entitled “Proteomics 2003.” The proteomics market, according to the report, has already grown from $1.1 billion in 2001 to almost $1.4 billion in 2002, and is continuing to grow. The study evaluates 75 proteomics companies in the US and in Europe and contains interviews with proteomics experts, three scenarios for the future of the industry, and a quantitative market model. It is available as a single user print version or as an electronic site license.
