Analysis of transcription in the Drosophila melanogaster testis

(Submitter supplied) Identification and annotation of all the genes in the sequenced Drosophila genome is a work in progress. Wild-type testis function requires many genes and is thus of potentially high value for the identification of transcription units. We therefore undertook a survey of the repertoire of genes expressed in the Drosophila testis by computational and microarray analysis. We generated 3141 high-quality testis expressed sequence tags (ESTs). more...

Dmel.testis.1.0

(Submitter supplied) The array was assembled using 1,681 testes ESTs, representing 1,527 Drosophila melanogaster EST sequences and 144 anonymous clones from the bs collection (CLONE_ID). An aliquot of the same DNA preparation used in the sequencing reactions (GB_ACC), diluted 2/50 in TE, provided material for the PCRs. Inserts were PCR amplified (1X PCR buffer [Life Technologies], 1.5 mM MgCl2, 0.2 mM dNTPs, 1 µM T7 22-mer primer, 1 µM T3 20-mer primer, 2 µl of plasmid DNA dilution [approximately 10 ng], 0.035 U/µl recombinant Taq DNA polymerase [Life Technologies], in a volume of 100 µl, cycled 94C 2 min, 30X[94 C 0.5 min, 55 C 0.5 min, 2.5 min 72 C], 10 min 72 C in a PTC-225 DNA Engine Tetrad [MJ Research]), and successful amplification was confirmed by agarose gel electrophoresis (PCR-QC: passed = product present, failed = no product). more...
