Transcription

1 Whole Transcriptome Sequencing/RNA-Seq RNA Seq refers to the use of high throughput next genera on sequencing technologies to sequence complementary DNA (cdna) sequences. Successful whole transcriptome analysis depends on RNA quality and efficient conversion into cdna libraries. The en re pool of RNA present in the sample is converted into cdna copies, sequenced and mapped on to a reference genome. Xcelris Genomics helps you with the best solu ons for transcriptome sequencing on various pla orms like Illumina MiSeq, HiSeq 2000,/2500 SOLiD 4, Ion Torrent Life Technologies and Roche GS FLX Titanium etc. These technologies offer powerful combina on of readlength and fragment or paired end library flexibility for transcriptomes of various sizes. This allows profiling of the whole popula on of mrna and enables mapping and digital quan fica on of whole transcriptome. We have successfully established accurate and comprehensive methodologies for animal, plants, bacteria, fungi and many more. Barcoding/Indexing can be carried to allow RNA Seq of mul ple samples in single run/lane/slide. Analysis of the reads generated by the sequencer depends on presence or absence of reference genome. In non model organisms, the data generated is assembled using the denovo approach. The reference based approach is preferred for model organisms whose genomes are available along with proper annota ons. Requirement for WTA: We accept isolated RNA, microbial cultures (non pathogenic), plant ssues etc. Isolated Total RNA: 8 10µg of total RNA should be provided with RNA Integrity Number (RIN)> 6. RNA must not be degraded & should be free from DNA contamina on. Quality control of RNA samples: Samples will be subjected to both qualifica on, quan fica on and those having RIN > 6 will be QC passed. However, inclusion of low RIN value of the samples will be processed upon customer s confirma on. Op onal: Isola on of total RNA from plants, microbial (non pathogenic) & fungal samples Xcelris will isolate total RNA from various parts of plant ssues, fungal & bacterial cultures. Standardiza on is required for certain samples to obtain good quality & quan ty suitable for RNA Seq experiment, and will be charged separately. Microbial cultures (non pathogenic): Pure isolated culture in 10 15% glycerol stock Plant ssues (seedling, leaf, stem, flower, fruit, grain etc.) Minimum 3 5 gm of ssue sample should be transported in RNAlater. The volume of RNAlater should be at least ten mes the volume of ssue. Plant ssue samples should be harvested and immediately immersed in RNAlater solu on. Note: All types of samples should be transported in dry ice ( 20 C) containing cool packs to Xcelris Genomics, Ahmedabad, Gujarat, India. Brief methodology for WTA/RNA Seq: The comprehensive methodology that Xcelris follows for the transcriptome sequencing with years of experience using Next Genera on Technology is: RNA isola on (Op onal) Quality check of RNA sample to assess RIN > 6 Prepara on of whole transcr ptome/rna Seq library for various pla orm
