AIMS: To detect non-viral mRNA in human plasma that has been frozen for three years using a new protocol. METHODS: Plasma from 15 patients with colorectal cancer and 10 normal subjects was separated and frozen with Trizol at -80 degrees C for three years. As a control measure, plasma from...
Magnetic Bead mRNA Extraction and Enrichment Kits Oligo(dT)/Magnetic Capture Methods Column methods for mRNA purification are reliable but require extensive manual interaction, which means more time and reduced throughput. Magnetic beads conjugated with oligo(dT) offer...
对于培养细胞,每次mRNA提取所用的细胞数量上下限分别为108和106。对于纯化的mRNA,则分别用紫外分光光度计测定数量和纯度,用凝胶电泳分析完整性。操作步骤及每步需注意的事项按照PolyATtract System 1000的protocol进行,并作了些修改,具体如下。1.收集细胞² 清洁工作 用干净纱布擦拭桌面...

Total RNA was extracted from cells using a Total RNA Extraction Kit (R6812-01HP, Omega, United States). 1000 ng cDNA was synthesized with the aid of a cDNA synthesis kit (RR036A, Takara, Japan), diluted in 200 μL of ddH2O. A total of 10 μL of the qRT-PCR mix, consisting of...
Isoform sequencing (Iso-Seq) uses long-read technology to produce highly accurate full-length reads of mRNA transcripts. Visualization of individual mRNA molecules can reveal new details of transcript variation within understudied portions of mRNA, such as the 5′ untranslated region (UTR). ...
