    15. We have noticed some of the genes are human,rat,arabidopsis etc. What is the relationship of the mouse clone to human,rat or arabidopsis gene?. What similarity is there in sequence, gene function or other?. What is the process of assigning the gene id's to the sequences?

    We compared NIA Mouse cDNA Clone Set sequences against NCBI 'nt' and NCBI Mouse RefSeq sequences. We store top 20 hits for each sequence in our database. We developed internal clone annotation alogorithm which will pick the best hit for the sequence. It will eliminate Genomic and other hits. If there is no mouse best hit then it will choose other species best hit.
     
    16. Is there any way to search the list of genes for a given gene product, for example "connexin43"?

    You can search NIA Mouse cDNA database using your gene product name for ex: connexin43 on NIA Mouse cDNA Clone Availability web page.
    Please enter your gene product name in the text box and select "NCBI Mouse UniGene Gene Symbol". Current gene symbol in the Gene Symbol(s) column will be in red color.
     
    17. We are using NIA 15k Clone Set in our lab. I am looking for "H3027H10" clone sequence. When I look at your web site i found three different sequences (i.e H3027H10-3, H3027H10-5, G0110A02-3). Why is this?. If i click on one these seqnames i get a list of search sequence,masked sequence and trimmed sequence. What do these different sequences mean?. Which sequence belongs to H3027H10 clone?

    H3027H10 (daughter) clone was rearrayed from G0110A02 (parent) clone. We sequenced daughter clones of NIA 15k and NIA 7.4k in both directions (3' -> 5'(3prime) and 5' -> 3' (5prime)). We verified NIA 15k clone (H3027H10) identity by comparing H3027H10-3 (3 prime sequence of daughter) and G0110A02-3 (3 prime sequence of parent). When the clone is verified you can use either daughter clone sequence (H3027H10-3 or H3027H10-5) or parent clone sequence (G0110A02-3). H3027H10-3 means sequence obtained from sequencing read of H3027H10 clone from 3' -> 5' direction. H3027H10-5 means seqeunce obtained from sequencing read of H3027H10 clone from 5' -> 3' direction. We receive the following three different sequences from sequencing of a clone.
    1. Raw Sequence: This is raw sequences we receive from sequencer
    2. Trim Sequence: The bases for this sequence were called by PHRED with an average 97% accuracy using the same trace file as was used to call 'searchseq'. This data may be longer, but less accurate than the 'searchseq'. We attempt to trim the vector, but not the Not1 and PolyT from this sequence.
    3. Search Sequence: The trace file for this sequence was read by PHRED and the bases were called with an average 99% accuracy. We attempt to trim the vector, Not1 site and PolyT from this sequence. All data processing e.g. RepeatMasking is done using this sequence
    4. Masked Sequence: We used repeat masker to mask search sequence. This is final sequence after repeats were masked. We are using this sequence for blast searches.
     
    18. How to search the database with general keywords (e.g. apoptosis) to obtain an appropriate list of genes?

    Currently you can search NIA 15k and NIA 7.4k Mouse cDNA Clone Sets using general keywords. You can use NIA Clone Set Gene Ontology Term Finder tool to obtain Gene Lists which have your keyword as function name.
    NIA Clone Set Gene Ontology Term Finder Tool is available at: http://lgsun.grc.nia.nih.gov/cDNA/NIA-CloneSet-GoTermFinder.html
    You can search for specific Gene Ontology terms. If you want to download all the Gene Ontology terms please don't enter any text in the text boxes.
     
    19. I didn't find my question in the FAQ page. What should I do?

    If your question was not answered in the FAQ page please send an email to Webmaster with the details.
     
    20. We would like to check PCR product sizes as part of our Quality Control. Where can I find insert sizes of the NIA Mouse Clone Set Clones?

    We don't have PCR product size information for NIA Clone Sets. You can visit the following NIA Clone Set distribution centers web sites to view NIA Clone Set Clones PCR product sizes
    NIA Mouse 15k Clone Set

    NIA Mouse 7.4k Clone Set
     
    21. How are the NIA Mouse cDNA Clones numbered?

    Clone Names: All NIA Mouse cDNA clones, including ones that had been done in our laboratory before moving to NIA, have been named in the following manner. As an example of NIA naming conventions, a clone might be named J0054A09. The first part of the name (one letter and four digits), in this example J0054 gives the serial number of the plate where the clone can be found. This final part of the name (one letter and two digits), in this example A09 gives the well position of the clone in the plate. (Row "A" Column "09" on the plate)
    Sequence Names: Sequences obtained from the 5.-end of cDNA clone (e.g., H3078A10) are named with .-5. (e.g., H3078A10-5), whereas the sequences obtained from the 3.-end of cDNA clone are named with .-3. (e.g., H3078A10-3). When these two sequences were overlapped and assembled by Phred/Phrap, the assembled sequences are named with .-0. (e.g., H3078A10-0).
     
    22. We are interested in obtaining NIA Mouse cDNA Clone Sets. Could you tell me from which lab you receommend I try to get it (for a reasonable fee)? Also could you tell me whether there is a list of papers that have been published using this clone set?

    NIA Mouse clone sets (NIA 15k & NIA 7.4k) have been made freely available to the academic and other non-profit organizations. However, since our laboratory does not have a capacity to send otu the clone sets to individual laboratories, we have made an arrangement with laboratories/centers (distribution centers) who kindly agree to redistribute the cDNA Clone Sets. Although we have shipped the clone sets to the distribution centers for free of charge, the centers will be allowed to charge nominal fees in order to recover costs of materials, shipping and handling. Neither our laboratory nor NIH will not receive any monetary or material returns from the distribution centers. The centers do not have an obligation to redistribute the clone set. The details about this arrangement and the contact information of the distibution centers is available at the following web sites.
     
    23. I wish to use NIA Mouse 15 k microarray clones but I have one doubt: (1) Are these clones spotted on to a chip so that I can directly use them for probing with my RNA samples? If yes where can I get the micro array chip?.

    We do not provide microarrays. You will probably have two options.
    1. If you know any microarray facility nearby or at your institute, please check whether they have the NIA mouse cDNA clone set (Tanaka TS, et al., Proc. Natl. Acad. Sci. USA, 97: 9127-9132. [PMID: 10922068];38. Kargul GJ, et al., Nature Genetics, 28:17-18. [PMID: 11326268]; VanBuren V, et al. Genome Res 12: 1999-2003. [PMID: 12466305]) and have prepared the arrays. The clone sets have been made available to the research community. Please check the following web sites for the details.

      NIA Mouse 15k Clone Set
      NIA Mouse 7.4k Clone Set

    2. We have worked with Agilent to develop 60-mer oligonucleotide microarrays on glass-slide (Carter M. et al., Genome Res.13: 1011-21. [PMID: 12727912]), which is commercially available from Agilent. This array, called Mouse Development Arrays, roughly corresponds to the NIA mouse 15K and 7.4K cDNA clone sets.

      For more information please visit Mouse Development Oligo Array web page.
     
    24. Can you please tell me what primers were used to obtain the 3' and 5' sequences. For example, was M13 Forward used to obtain 5' sequences for both sets, etc. Also, were the sequencing templates plasmid DNA or PCR products?>

    We used the following primers to obtain 3' and 5' sequences.

    3' Sequence: -21M13Forward (3') 5' TGTAAAACGACGGCCAGT 3'
    5' Sequence: M13 Reverse (5') 5' CAGGAAACAGCTATGACC 3'

    Sequencing templates were plasmid DNA.
