EasyPrep miRNA Extraction Kit
Cat#DPT-BE01
EasyPrep miRNA Extraction Kit utilizes a silica-based system to enrich and purify small RNA, including miRNA, small interfering RNA (siRNA), small nuclear RNA (snRNA), and total RNA from various sample sources (cell, animal tissue, plant tissue, serum, plasma), especially for small RNA of <200 nt. The lysis buffer in the kit is optimized to exert excellent lysis ability and isolation efficiency. High-quality isolated product without contamination of DNA and protein could be obtained within 1 hour, and directly used in Northern Blot, Dot Blot, Poly A screening, in vitro translation, RNase protection analysis, and also molecular cloning.
- Efficient: Completed within 1 hr
- Quality: silica-based system to yield high-purity small RNA product
- Flexible: Excellent lysis ability for various sample sources
Q1. There are six sequences as controls for human miRNA assay, and what are the differences and significance among them? How to apply the control within miRNA profiling?
A：cel-miR-39-3p, cel-miR-238-3p and cel-miR-54-3p are miRNA from Caenorhabditis elegans and would be used as exogenous control [1] or spike-in control. SNORD44, SNORD48, and RNU6B are endogenous controls when profiling human miRNA, and would be used as housekeeping genes [2]
The client could choose SNORD44, SNORD48, and RNU6B as endogenous controls according to the sample types or experiment design. If there is no suitable design of endogenous control, using exogenous control is also applied. When using exogenous control, the corresponding spike-in RNA should be added into RNA samples before assay. Customized control is the other option and available from TOOLS.
Q2. In mRNA profiling, the cDNA samples used in qPCR are synthesized simultaneously, and GAPDH is used as the endogenous control for quantification. However, the stem-loop primer RT method of TOOLS is to synthesize the cDNA of each target separately. Does it make sense to use endogenous control for quantification?
A：Since miRNA sequence is much shorter compared to mRNA, and in order to improve the sensitivity and specificity of each miRNA target, the stem-loop RT method is considered a very efficient and excellent method for miRNA quantification. Indeed, each miRNA target including control is separately assayed, but the quantification based on all reactions using the same RNA sample under very same experiment conditions.
Q3. Is there designed and validated control for Mouse and Rat??
A：Not yet. More search and corresponding materials published are needed, and if there is any, the client could order customized synthesis by us.
