CIL
Cambridge Isotope Laboratories CIL Modern drug development programs require rapid screening of myriad potential drug candidates to identify those targets that are amenable to further in depth study of activity and efficacy. To facilitate this process, intricate NMR techniques utilizing stable isotope labeled proteins have been developed to study protein interactions with small molecules, oligonucleotides and other proteins. Since the completion of the Human Genome Project, the focus of Molecular Biology has turned to the study of the Human Proteome to identify protein interactions at the molec- ular level to better understand functional relationships among proteins. New techniques that combine stable isotope labeling and Mass Spectrometry are proving successful at identifying and quantitating proteins in complex mixtures. The success of these NMR and MS applications depends upon the availability of a wide variety of stable isotope labeled biochemicals and reagents. Cambridge Isotope Laboratories, Inc. has been working with chemists and biochemists for the past 25 years to help these researchers advance their programs by providing the highest quality, most innovative stable isotope labeled products for the fields of Structural and Functional Genomics and Proteomics. CIL also offers a wide variety of products to support the newer fields of Metabolomics and Glyconomics. This brochure describes the wide variety of products that CIL offers in support of these Life Science research efforts. If your project requires stable isotope labeling, CIL has the solution.

with one majorInsect Cell draw back: the proteins are expressed without post-translational modification or the proper 3-dimensional fold. In order to study eukaryotic proteins that are glycosylated and exhibit proper folding with intact disulfide bridges, it is necessary to express the protein in a eukaryotic cell system. Yeast systems can and have been used for this purpose but many proteins of interest require a higher order system such as insect expression systems. Cambridge Isotope Laboratories, Inc. has developed a proprietary medium specifically for the expression of isotopically labeled eukaryotic proteins. The CIL media is designed for many types of labeling systems, from uniform 13C; 15N labeling of all amino acids in the protein to selective labeling of one or more amino acid residues with any of the labeling patterns in CIL’s amino acids. These media have been tested for growth rates and expression levels in the SF9/ Baculovirus expression system with results comparable to unlabeled commercial media. Please see the results on page 14. Samples of unlabeled BioExpress® 2000 are available for CIL customers to test protein expression in their laboratories. Instructions for use are included on page 15. CIL is pleased to quote on custom protein expression in insect cell systems. Please contact your CIL Sales Rep or call CIL for more information.

16 978-749-8000 800-322-1174 Fax: 978-749-2768 www.isotope.com Recombinant Protein Expression Products Specifically Labeled Proteins ForSystems some NMRBacterial Expression and Mass Spectrometry (Mass Spec) applications it is desirable to selectively label the protein at only one or a few types of amino acid residues. This approach is used in NMR studies to filter out unwanted signals from overlapping resonances and thereby simplify the NMR spectra in order that unequivocal resonance assignments can be made. Selective labeling of proteins is used in Mass Spec to aid in the identification and quantitation of peptide fragments of proteins, yielding new insights regarding metabolism. There are a number of applications of these techniques reported in the literature and some references can be found on pages 41-42. If you want to focus on a certain region of the protein (e.g. hydrophobic core, charged residues, methyl containing residues, etc.) the following amino acids and α-Keto acids provide many choices for your experiments. Bacterial and Insect Expression Systems Bacterial cell systems will synthesize protein from simple nutrients such as glucose and ammonium chloride. If, however, amino acids are present in the media, the cells will exhaust the supply of the amino acid in protein production before utilizing the simpler starting materials. This technique provides an excellent opportunity to incorporate selective isotope labels into proteins for NMR or Mass Spec analysis. CIL maintains the world’s largest inventory of stable isotope labeled amino acids for your research applications. Insect and mammalian cell growth media must contain precise amounts of each amino acid for proper growth and protein expression. It is possible to obtain selectively labeled proteins using our amino acid and carbo- hydrate products. CIL is pleased to quote on custom made media containing any combination of labeled and unlabeled amino acids for your individual experiments.

The resulting 1H NMR spectra of the expressed protein 13 can be simplified through the use of (U- C6;D7) Glucose and D2O in the minimal media. Most recently, NMR studies of proteins expressed using α-Keto acids with specifically deuterated and 13C labeled methyl groups have provided significant information about the intermolecular interactions in the hydrophobic cores of proteins.

Cell Free Protein Synthesis TheCell Free Synthesis rapidly advancing field of cell free protein synthesis appears most promising for structural genomics research and protein structure determination. The obvious advantages of the technique include the ability to produce large quantities of proteins that are difficult to express in vivo due to their solubility or cytotoxic characteristics. Extensive protein purification is not required and labeling proteins with stable isotopes is very straightforward. If your lab has the capability to do cell free protein synthesis, CIL amino acids can be used in place of the unlabeled analogs to obtain sufficient quantities of labeled protein for NMR structural analysis. The individual amino acids listed on pages 17-19 can be used together to prepare cocktails of all 20 amino acids or individually for selective labeling experiments. CIL also offers amino acid mixtures (listed below) that can be used as is or supplemented to achieve any concentration required.

In these studies the protein is divided into two or more samples that are individually tagged with native or stable isotope labeled reagents and subjected to a variety of treatments. The MS results from these experiments provide new insight into protein function and protein/protein interactions. This wealth of new information adds to the mapping of an organism’s complete Proteome. A few references describing these techniques are listed on page 42. Listed below is a sample offering of potential isotope labeled tagging reagents. Please inquire about availability of other products which may be used to tag proteins or peptides.

The effect is much greater, however, for cryoprobes due to the high Q of the resonant circuit. It has been reported that a cryoprobe may experience a 75% loss in sensitivity compared to a 30% loss for a room temperature probe with the same sample. The use of organic buffers in place of salts of high ionic strength can minimize this effect. In fact, the loss of 1H sensitivity, measured on a triple resonance cryogenic probe at 500 MHz1, is only about 10% for samples buffered with 200 mM TRIS. Listed below are the organic buffers that CIL offers in deuterated form for our customers to use in cryoprobes. All items are routinely available from stock; please contact us or your local CIL distributor to arrange for an immediate shipment.
