Tissue, Total RNA, Human Adult Normal, Placenta, BioGenomics™

Total RNAs are available from almost 200 different human adult and fetal normal tissues, human diseased and tumor tissues, as well as mouse, rat, and monkey tissues. Total RNAs are provided ready-to-use for Northern blotting, cDNA synthesis, RNA protection, and RNA differential display. |Total RNA isolation is performed using proprietary techniques. Contamination by RNase, genomic DNA polysaccharides, and proteoglycans has been effectively eliminated. The integrity of the total RNAs is assured by checking for a ratio of greater than 1/1 between 28S and 18S ribosomal RNA. We guarantee high efficiency reverse transcription. ||Features:|• Total RNA isolated from a wide variety of hard to obtain tissues |• Decontamination of polysaccharide, proteoglycan, RNase, and genomic DNA |• Extensive quality control procedures to ensure high quality |• High efficiency reverse transcription |• Available documentation of tissues' clinical histories (additional cost)||Quality Control:|1. The integrity of the RNA is examined by visual inspectiuon for the presence of intact bands of 18s and 28s RNA when electrophoreses on a denaturing agarose gel. The quality and purity of total RNA were tested by spectrophotomer. (A260/280 = 1.8-2.0 detected in 10mM Tris-Cl, pH 7.5).|2. The RNA is treated by DNAse I. It is tested as DNA free RNA by PCR.|3. cDNA synthesis is successfully performed by using this RNA as template.||Applications:|• Northern Blotting, RT-PCR, and RACE |• cDNA synthesis and cDNA library construction |• cDNA probe for profiling study in gene expression |• RNA protection and primer extension |• RNA display |• Purification of mRNA||Storage and Stability:|May be stored at 4°C for short-term only. For long-term storage, store at -70°C. Aliquots are stable for at least 6months at -70°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
