Total RNA was extracted from mouse testis following the manufacturer's protocol using the TRI Reagent (Sigma, T9424). Total RNA was reverse transcribed into cDNA by Hifair 1st Strand cDNA Synthesis Super Mix for qPCR (gDNA digester plus) (11141ES10, YEASEN, Shanghai, China). Slc25a26 gene was cloned from cDNA using nested PCR by Prime-STAR HS DNA Polymerase (R010A, TaKaRa) with 2 primer pairs (the first pair: forward, 5′-AAGTAGTTGCTCCATATCCCG-3′; reverse, 5′-TTGTAGCCAGTTTGCTTTCC-3′; the 2nd pair: forward, 5′-CTAGCTAGCCACCATGGACGCGCCGGGCT-3′; reverse, 5′-CTGCTAA CCGGTGGTGGGCTCTTCCTGCCCACC-3′). PCR products were digested with NheI and AgeI (NEB Inc., MA, USA) and ligated into PVAX1 vector with FLAG tag. cRNAs were in vitro transcribed and capped from linearized plasmids using mMESSAGE mMACHINE Kit (AM1344, Invitrogen) and Poly(A) Tailing Kit (AM1350, Invitrogen) according to the manufacturer's instruction. Synthesized RNA was aliquoted and stored at -80°C.

A total of 25-30 oocytes/zygotes or 20 cleavage embryos or 15 blastocysts were collected, respectively. Total RNA was extracted using the TRI Reagent (Sigma, T9424) and reverse transcribed into cDNA by Hifair 1st Strand cDNA Synthesis Super Mix for qPCR (gDNA digester plus) (11141ES10, YEASEN, Shanghai, China). Each PCR reaction consisted of 10 μl of Hieff qPCR SYBR Green Master Mix (High Rox Plus) (11203ES03, YEASEN, Shanghai, China), 8.2 μl of water, 1 μl of cDNA sample, and 0.8 μl of gene-specific primers (5 μM; Slc25a26 primers: forward, 5′-TCTGGGGCAACAGTGTGTAG-3′; reverse, 5′-TACTAAGTGTGTGCGGCGGT-3′; mt-Cytb primers: forward, 5′-ACCTCAAAGCAACGAAGCCT-3′; reverse, 5′-TGGGTGTTCTACTGGTTGGC-3′). Real-time PCR was performed by the StepOnePlus Real-Time PCR system (Applied Biosystems, USA). mRNA levels were normalized to Gapdh. The experiments were performed for at least three times.

Isoform-specific RT-qPCR protocol for AS events

Check if the same lab product or an alternative is used in the 5 most similar protocols
To distinguish AS events, the reverse transcription (RT)-PCR was performed. Brie y, the RNA used for Iso-Seq was isolated using EZ-10 DNA away RNA Mini-Preps Kit (Sangon, https://www.sangon.com) and synthesized to complementary DNA using the Hifair ® 1st Strand cDNA Synthesis SuperMix for qPCR gDNA digester plus (Yeasen). Isoform-speci c primers were designed using Vector NTI software (Supplementary Table S1). PCR ampli cation was performed using 2×Taq PCR Master Mix (K1034, https://www.apexbt.com/) and the PCR products were showed in agarose gel stained with GoodView TM Nucleic Acid Stain (Apr-13-2021, HGV-, https://www.sbsbio.com).
BlazeTaq TM SYBR ® Green qPCR Mix 2.0 (GeneCopoeia, USA) was used for RT-qPCR reactions on a CFX96 Real-time System (BIO-RAD, USA). The ampli cation program was brie y described in previous study (Wagner 2013 (link)). To ensure the precise and reproducible results, each sample was replicated three times and Ef1α in potato were used for each sample as an endogenous control (Supplementary Table S1). The formula F = 2 -ΔΔCt was used to calculate the relative expression levels of selected genes.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
