RNA Hybridization of Sorghum Internode

Check if the same lab product or an alternative is used in the 5 most similar protocols
The sorghum 4th internode stem samples were embedded in paraffin and the following RNA hybridization process was carried out as previously described (Wang et al., 2021 (link)). DNA template for RNA probes was amplified from sorghum cDNA using gene-specific primers (see Supplementary Table S6). RNA probes were synthesized in vitro using MEGAscript™ T7 Transcription Kit for SbSWEET1A probes and MEGAscript™ SP6 Transcription Kit for SbCIN5 probes (Thermo Fisher Scientific). RNA probes were labeled using fluorescein-12-UTP and were hydrolyzed to ~100 nucleotides. Hybridized probes were detected with Anti-Fluorescein-AP (Sigma-Aldrich) and the substrates 5-bromo-4-chloro-3-indolyl phosphate/nitro blue tetrazolium (BCIP/NBT).

Whole-mount in situ Hybridization Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
Whole-mount in situ hybridization was performed as previously described (deCarvalho et al., 2014 (link); Gamse et al., 2002 (link)). In brief, larvae and dissected brains were fixed in 4% paraformaldehyde (P6148, Sigma-Aldrich) in 1 X PBS (phosphate-buffered saline) at 4 °C overnight. To synthesize RNA probes, the following restriction enzymes and RNA polymerases were used: lratd2a (BamHI/T7), fos (NotI/SP6), slc5a7a (NotI/SP6), kctd12.1 (EcoRI/T7) (deCarvalho et al., 2013 (link); Hong et al., 2013 (link)). Probes were labeled with UTP-digoxigenin (11093274910, Roche) and samples incubated at 70 °C in hybridization solution containing 50% formamide. Hybridized probes were detected using alkaline phosphatase-conjugated antibodies (Anti-Digoxigenin-AP, #11093274910, and Anti-Fluorescein-AP, #11426338910, Sigma-Aldrich) and visualized by staining with 4-nitro blue tetrazolium (NBT, #11383213001, Roche), 5-bromo-4-chloro-3-indolyl-phosphate (BCIP, #11383221001, Roche) and 2-(4-Iodophenyl)–3-(4-nitrophenyl)–5-phenyltetrazolium Chloride (INT, #I00671G, Fisher Scientific).

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.
