换一换How to make Tol2 mRNA
FishFloorUCL
These are instructions to make highly concentrated (> 1000 ng/µL) Tol2 mRNA. Note, the in-vitro transcription kit (mMESSAGE mMACHINE) is not cheap. 5–6 reactions like the protocol suggests come to ~ 100–120£, so please be thrifty with it.

Scott Nichols
This HCR-FISH protocol using probes and amplifiers from Molecular Instruments is intended for gemmule-hatched freshwater sponges grown in 35 mm coverslip bottom cell-culture dishes with a 10 mm inner-well diameter.
AI 解读Two-Tailed RT-qPCR for the Quantification of A-to-I-Edited microRNA Isoforms
Gjendine Voss, Yvonne Ceder, Gjendine Voss, Yvonne Ceder
MicroRNAs are short non-coding RNAs with important functions in the regulation of gene expression in healthy and diseased tissues. To optimally utilize the biological and clinical information that is contained in microRNA expression levels, tools for their accurate and cost-effective quantification are needed. While the standard method, qPCR, allows for quick and cheap microRNA quantification, specificity is limited due to the short lengths of microRNAs and the high similarity between closely related microRNA family members. A-to-I editing can further diversify the microRNA pool by altering individual nucleotides. There is currently a lack of protocols for the accurate quantification of A-to-I-edited microRNA isoforms using qPCR. Here, we describe a protocol to quantify microRNA editing isoforms using two-tailed RT-qPCR, with either SYBR Green or hydrolysis probes. The user will perform reverse transcription of RNA samples, generate standard curves, and quantify the resulting cDNA in the following qPCR step. We also give guidelines for primer design and for the evaluation of assays using synthetic oligonucleotides. These tools are expected to be transferable to any A-to-I-edited microRNA and its isoforms. © 2023 The Authors.
