Eukaryotic mRNA sequencing-Illumina

mRNA sequencing enables profiling of all mRNAs transcripted from cells under specific conditions. It is a powerful technology for revealing gene expression profile, gene structures and molecular mechanisms of certain biological processes. To date, mRNA sequencing has been widely employed in fundamental research, clinical diagnostics, drug development, etc.

Platform: Illumina NovaSeq 6000

Sample Requirements and Delivery

Library	Sequencing strategy	Data recommended	Quality Control
Poly A enriched	Illumina PE150	6 Gb	Q30≥85%

Sample Requirements:

Nucleotides:

Purity	Integrity	Amount
OD260/280≥1.7-2.5 OD260/230≥0.5-2.5Limited or no protein or DNA contamination shown on gel.	For plants: RIN≥6.5;For animals: RIN≥7;28S/18S≥1.0;limited or no baseline elevation	Conc. ≥30 ng/μl; Volumn ≥ 10 μl; Total ≥ 1.5 μg

Tissue: Weight(dry): ≥1 g
*For tissue smaller than 5 mg, we recommend to send flash frozen(in liquid nitrogen) tissue sample.

Cell suspension: Cell count = 3×10⁶ - 1×10⁷
*We recommend to ship frozen cell lysate. In case that cell counts smaller than 5×105, flash frozen in liquid nitrogen is recommended, which is preferable for micro extraction.

Blood samples: Volume≥1 ml

Microorganism: Mass ≥ 1 g

Recommended Sample Delivery

Container: 2 ml centrifuge tube (Tin foil is not recommended)

Sample labeling: Group+replicate e.g. A1, A2, A3; B1, B2, B3... ...

Shipment:

Dry-ice: Samples need to be packed in bags and buried in dry-ice.
RNAstable tubes: RNA samples can be dried in RNA stabilization tube(e.g. RNAstable®) and shipped in room temperature.
