l Sheldon Biotechnology Centre The Sheldon Biotechnology Centre selVes as the core facility for biotechnology research at McGill University. We have state-of-the-art technical support facilities and offer reliable low cost selVice to investigators. SelVices available at the Sheldon Biotechnology Centre are oligo- nucleotide synthesis/purification, peptide synthesis, protein/peptide sequencing, protein/peptide amino acid analysis and mass spectroscopy. We are dedicated to remaining in the forefront of recombinant DNA methodology, protein sequencing analysis and protein separations. This objective will selVe investiga- tors undertaking new studies and in the transfer of information between various scientific disciplines. Collaborative Program The Sheldon Biotechnology Centre represents McGill University and its affiliated hospitals and research institutes to the larger community on matters relating to biotechno- logy. We recognize the need to form strong relationships with colleagues in industry. Our Biotech- nology Collaborative Program facilitates and coordinates the development of joint ventures between the business community and McGill researchers working in the field of biotechnology. Victor L. Cape Lecture Series The focus of this series is on biotechnology. The program pro- vides a forum for industry, govern- ment and university to meet and discuss mutual interests in the field. Recent speakers have included Professor Luc Montagnier, Pasteur Institute whose topic was "Biotechnology in AIDS Diagnosis and Prevention"; Dr. Webster K. Cavenee, Director, Ludwig Institute for Cancer Research whose topic was "Molecular Genetics of Human Cancer" and Dr. Leroy E. Hood, Director, Science and Technology Center for Biotechnology whose topic was "Biotechnology, the Genome Initiative and Medicine in the Twenty-first Century". We strive to maintain a high standard of internationally recognized speakers. Teaching Program in Biotechnology The Minor Program in Biotech- nology is administered for the Faculties of Engineering, Medicine, Agriculture and Science by the Department of Biology. This Program allows students to select a package of courses that will broaden their perspective in areas impacting on biotechnology. Biotechnology 505B is a key component of the Minor Program in Biotechnology and an important course for graduate students seeking to expand their knowledge in biotechnology. This multidisci- plinary course is taught by out- standing McGill professors and researchers from industry. Each lecturer presents the significance of his or her own research to the field of biotechnology. Mass Spectroscopy Application of mass spectroscopy (MS) to protein characterization is a relatively new field. Several applications have been realized and are routinely available, how- ever many new applications are yet to be realized. Mass spectroscopy is readily applied to quality control of synthetic peptides, characterization of whole protein digests, identification of post-translational modifications, etc. The Sheldon Biotechnology Centre has access to two mass spectrom- eters which employ different' ionization technologies: fast atom bombardment (FAB) and electro- spray (ES) ionizations. FAB-MSis useful in the low mass range and may provide fragmentation infor- mation. ES-MSis a milder ioniza- tion technique and allows larger molecules (up to 100,000 amu) to be characterized. Sample analysis and data evaluation are provided for both technologies. Emphasis is placed on assessing the protein related requirement and providing guidance for appro- priate mass spectral analysis. Ordering All work is performed upon receipt of a valid purchase order.

Oligonucleotide Synthesis/PurificationSynthetic oligonucleotides areessential reagents to the molecularbiologist and are used in a widevariety of recombinant DNA manip-ulations, including DNA sequenc-ing, PCR amplification, site-directedmutagenesis, etc.

The Sheldon Biotechnology Centrehas capabilities for high throughputand flexibility. Using the GeneAssemble~ Plus, a 2 column DNAsynthesizer, we can provide youwith oligonucleotides of lengths toover 100 bases that include regularor modified bases such as inosineor methylated derivatives.

Peptide SynthesisA very broad range of applicationsrequire synthetic peptides. Peptidesynthesis can be time consumingwithout specialized scientists andproper equipment.

At the Sheldon BiotechnologyCentre we have state of the arttechnology and peptide chemiststhat guarantee the synthesis. Solidphase peptide synthesis is carriedout on the Biolynx™ PeptideSynthesizer which uses the Fmocpolyamide peptide synthesismethodology. Up to 3 columns inseries can be used for productionof peptide analogues with yields ofapproximately 0.2 mmole/column.We can synthesize up to 100 mg ofpeptide for all types of applications.

The purity of the cleaved and

(FPLC) give you complete assur-ance of successful synthesis, highyield and purity.

Oligonucleotides are cleaved anddeprotected at 550C for 16 hoursin concentrated ammoniumhydroxide. Purification by FPLCcan be completed within 24 to 48hours following deprotection.

The Sheldon Biotechnology Centreis the source for affordable syn-thetic oligonucleotides resulting inconsiderable savings to investigators.All oligonucleotides are guaran-teed. Should there be a problem,we will re-synthesize and/or re-purify without charge.

deprotected peptide is assessedusing the HPLC DfB System Twowhich is equipped with a RapidSpectral Detector. Depending onthe sequence, the purity of thecrude peptide varies between 70%and 95%. If your applicationrequires greater purity, we offercomplete purification and charac-terization services. We have capa-bilities for carrying out qualitycontrol at the level of amino acidanalysis, mass spectroscopy andlO-peptide sequencing, dependingon your needs.

Please contact the Facility Managerconcerning specific additionalrequirements such as peptidecouplings or incorporation ofmodified amino acid residues.

Protein/Peptide Amino Acid AnalysisAmino acid analysis is one of themost exacting application areas ofliquid chromatography. Resultshave to be both accurate andreproducible.

At the Sheldon BiotechnologyCentre, we use the Alpha PlusAmino Acid Analyzer. With thissystem, the amino acids of the mostcomplex protein hydrolysates orphysiological fluids can be analyzed.

If your demand is perfection in thechromatography of protein/peptidehydrolysates you will be impressedwith the excellent resolution thesulphonated polystyrene resinprovides. This is an important

advantage where samples are notpure proteins but contain manyother components. Hydrolysistime-course profiles and/or pre-hydrolysis chemical modificationsare available for exacting quantita-tion of residues modified, destroyedor slowly released during routinehydrolysis conditions.

For complex biological fluids, weoffer baseline separation betweenvirtually all 40 of the amino acidsand their derivatives which canoccur in physiological fluids. Thisis ideal for complex samples suchas urine, plant extracts and fermen-tation media.
