1. What is the Missouri S&T cDNA Resource Center?

The Missouri S&T cDNA Resource Center is a service provided by the faculty of the Department of Biological Sciences of Missouri University of Science and Technology.
The purpose of the cDNA Resource Center is to further scientific investigation by providing cDNA clones of human proteins involved in signal transduction processes. The goal of the Center is to accelerate scientific discovery in human biology and pathology. This is achieved by providing high quality clones for important signaling proteins in a timely manner.
By high quality, we mean that the clones are:

1. Sequence verified
2. Propagated in a versatile vector (pcDNA3.1+)
3. Free of extraneous 3' and 5' untranslated regions
4. Available in wild-type, epitope-tagged and common mutant forms (e.g., constitutively-active or dominant negative)
5. Expression-verified in most cases by coupled in vitro transcription/translation assays

By timely, we mean that the clones are

1. Most orders shipped within one business day by courier delivery (Federal Express).
   We expect this service to allow scientists to focus on basic biological questions without spending excessive amounts of time in procuring, preparing or verifying their own (or their colleagues) cDNA clones. We expect these clones to be particularly useful to scientists probing and reconstructing signal transduction pathways in model systems.

Biological research often involves the reconstruction of signaling pathways. The basic tools required in this work are the clones of the relevant interacting proteins. We found that we were spending inordinate amounts of time obtaining, verifying and modifying these clones. Accordingly, we felt that research would be accelerated and a great deal of duplicate effort eliminated if there was a service that provided rapid access to high quality sequence-verified clones.
We offer human clones because of their obvious inherent interest. We remove the untranslated regions because their presence often increases variability in expression. We utilize a standard vector to simplify handling procedures.

A $120 fee is charged to cover our costs for producing, verifying, and distributing the clones.

Usually the polymerase chain reaction (PCR) is used to amplify the ORF from commercially prepared cDNA. The PCR product is then subcloned into a plasmid vector (see below) and the sequence verified against published sequences. Discrepancies, if any, from the published sequence(s) are noted in the clone documentation. In the case of novel sequences, such as previously undescribed human orthologs, the predicted translation product is compared with amino acid sequence of orthologous proteins from other species. GenBank submissions are prepared to describe these data.
We have also obtained clones from investigators who wish to deposit their clones in the Resource Center (e.g., WOX1, AGS1). The ORFs of deposited clones are subcloned into the standard vector and the sequence of the insert verified. We thus maintain a standard "context" for each clone in the collection.

Clones are distributed by agreement in Invitrogen's pcDNA3.1+ vector.
pcDNA3.1+ This vector can be used for mammalian expression (CMV promoter, bovine growth hormone polyadenylation signal), production of sense strand RNA by in vitro transcription (T7), production of single stranded DNA (f1 origin), and production of stably transfected cell lines (neomycin resistance). The vector contains the ampicillin resistance gene and can be propagated in common E. coli strains. (www.invitrogen.com)
Please note that pcDNA3.1 is the property of the Invitrogen Corporation, Carlsbad, CA. In consideration for these materials, you agree that you will not, without prior written permission from Invitrogen: a) use that vector for any commercial purpose; b) amplify, duplicate, clone or otherwise use the vector or any part thereof independently of the gene insert provided; c) transfer the vector or any part thereof (except the gene insert) to third parties.

Clones can be ordered via our web page (www.cdna.org), by FAX (573 341-7609) or by telephone (573-341-7610). Purchase order (P.O.) numbers from research organizations based in the United States are accepted. Credit card (MasterCard or Visa) orders are accepted from all research organizations (US and international). Please be aware, if using a Bank Transfer for payment that the purchasing institution is responsible for any and all bank transfer fees.

Most orders received are usually shipped the same day the order was placed for courier delivery (Federal Express).
The clones are provided as dried DNA (approximately 1.0 g) on either a circle of Whatman #1 filter paper or dried within a 0.5ml screw-cap tube. Instructions for reconstituting the DNA are provided below.

To save on processing costs, only an invoice is shipped with the clones. For each clone, four forms of documentation can be downloaded from our web site: 1) an information sheet that contains details on the insert, including how the clone was obtained, any sequence discrepancies, and experimental mutagenesis details, if applicable; 2) a sequence sheet that contains the nucleotide sequence of the insert and the predicted translation product; 3) a text file in FASTA format containing the insert nucleotide sequence can be downloaded for use with your molecular biology software; 4) for the relevant clones a PDF file documenting expression in a coupled transcription/translation assay system. PDF files can be downloaded and viewed with Adobe Acrobat Reader (www.adobe.com).

Store clones at 4C until you are ready to use them. Clones are supplied as DNA (approximately 1.0 g) spotted onto either a Whatman #1 filter disks, or dried within a 0.5ml screw-cap tube.

Whatman Disk: To recover the DNA, put the filter paper into a 1.5 ml microcentrifuge tube. Add 100 l of TE buffer (10 mM TRIS base, 1 mM EDTA, pH 8.0) to the microcentrifuge tube, vortex briefly, incubate at room temperature for 5 minutes, and repeat the vortex. Centrifuge the tube for a few seconds and then remove the filter paper from the tube.

0.5ml Tube: Centrifuge the tube BEFORE OPENING to ensure pellet is at the bottom of the tube. Add 50ul of ddH20 or TE buffer (as above) and vortex or flick the tube to ensure that the pellet disolves.

For Both: Use 1-2 l of supernatant for use in transfecting E. coli by electroporation or chemical means. Please do not try to use the DNA directly for any application other than to transform bacteria and prepare a large stock.

The clones are supplied solely for research purposes. Details on use of the material are included on the Material Transfer Agreement that is available on this web site. Please note the restrictions on the use of the pcDNA3.1+ (see FAQ question #5), which is the property of the Invitrogen Corporation.

We would prefer that you do not for two reasons. First, for quality control purposes we would prefer to handle distribution of the clones ourselves. Although we cannot guarantee the suitability of the clones for a given research purpose, we will investigate, and correct, if appropriate, any sequence discrepancy from that provided in the documentation. Second, the future funding for the Missouri S&T cDNA Resource is contingent upon our meeting certain benchmarks for utilization. The two most important benchmarks are the number of clones we ship and citation of the resource in scientific manuscripts (see below). Hence, it is important that we quantify the number of clones that are supplied by the Resource and have a record of the laboratories using the clones to justify further development and maintenance of this service. All users of the clones should be aware of and agree to all points of the Material Transfer Agreement.
