Dynamic Transcriptome Analysis

Inquiry

Dynamic transcriptome sequencing aims to build an isoform database of different genes of a species, analyze transcripts and alternative splicing forms in different tissues, specific cells, of important periods. Based on next-generation sequencing or full-length transcriptome sequencing technologies, dynamic transcriptome sequencing can draw a fine-scale transcriptome map of cells/tissues/organs with spatiotemporal characteristics, reconstruct the dynamic network in the living system, and analyze the life process of a species from the transcript level and activity rules.

Overview

The dynamics and stage- or breed-specific expression patterns of genes may reflect the key functions they perform. Dynamic transcriptome analysis can be widely used in developmental biology research and genetics transcription regulation mechanism research, disease transcription regulation mechanism research, transcripts and alternative splicing database construction of economic species or model species, and more.

CD Genomics provides high quality and reliable dynamic transcriptome analysis service. We can identify period- or tissue-specific transcripts and construct dynamic functional networks based on the full spectrum of dynamic transcripts, as well as establish alternative splicing databases for species.

Sample Requirements

Tissue sample: plant sample > 500mg; animal sample > 300mg

Cell sample: cell amount: above 5×10⁶

Blood sample: Whole blood/whole blood isolated nucleated cells >3mL

RNA sample: RNA quantity: 30-300 μg; RNA purity: OD_260/280 = 1.6~2.3; OD_260/230 ≥ 1.5; RNA quality: 28S:18S ≥ 1.5 or RIN ≥ 7

Please make sure that the RNA is not significantly degraded.

Sample storage: RNA samples can be dissolved in ethanol or RNA-free ultrapure water, and stored at -80°C. Avoid repeated freezing and thawing during sample storage.

Shipping Method: The samples should be stored in a 1.5 mL Eppendorf tube, sealed with sealing film. Shipments are generally recommended to contain 5-10 pounds of dry ice per 24 hours.
