The Xenopus Gene Collection (XGC) is an NIH initiative
that supports the production of cDNA libraries, clones and
5'/3' sequences to provide a set of full-length (open reading frame)
sequences and cDNA clones of expressed genes for Xenopus laevis
and Xenopus tropicalis.
All resources generated by the XGC are publicly accessible to the
biomedical research community.
For an overview, see the
XGC Project Summary.
All XGC sequences are deposited in GenBank and the clones can be purchased from distributors of the IMAGE consortium. You can use "A Guide to Finding Mammalian Gene Collection (MGC) Clones and Evaluating Their Sequence" to assist in determining whether XGC cDNA clones for genes and transcripts of interest are available for purchase or sequence investigation (please note: the guide describes the process for mammalian clones, however it is the same for Xenopus clones as well).
With the conclusion of the XGC project in September 2008, the GenBank records of XGC sequences will be frozen, without further updates. Since the definition of what constitutes a full-length coding region for some of the genes and transcripts for which we have XGC clones will likely change in the future, users planning to order XGC clones will need to monitor for these changes. Users can make use of genome browsers and gene-specific databases, such as the UCSC Genome browser, NCBI’s Map Viewer, and Entrez Gene, to view the relevant regions of the genome (browsers) or gene-related information (Entrez Gene).
