Fluorescence in situ Hybridization of pfs and mocs1 mRNAs

Check if the same lab product or an alternative is used in the 5 most similar protocols
For fluorescence in situ hybridization, custom Stellaris® FISH probes were designed to detect pfs/mocs1 mRNAs by utilizing the Stellaris® FISH Probe Designer (Biosearch Technologies, Inc., Petaluma, CA) available online at www.biosearchtech.com/stellarisdesigner. The probes were conjugated to the Quasar670 dye and used in FISH assays as described previously [50 (link)]. Confocal microscopy was performed by using Olympus laser scanning microscope FV1000. For comparing the relative levels of pfs mRNAs in wild-type and pfs mutant flies, fluorescent intensities in the central brain region were measured.
To examine the expression pattern of genomic-pfs tagged with GFP, adult heads were dissected in phosphate buffer. The brains were immediately mounted on glass slides in phosphate buffer and imaged with confocal microscopy using Olympus laser scanning microscope FV1000.

Custom RNA FISH Probes were designed against mouse CCL2 mRNA (NM_011333) utilizing the Stellaris® FISH Probe Designer (Biosearch Technologies, Inc., Petaluma, CA) available online at www.biosearchtech.com/stellarisdesigner. 10μm sections of prostate from naive and EAP treated mice were hybridized with the Stellaris FISH Probe set pooled by 14 singly labeled mouse CCL2 probes (tgagccaacacgtggatgct, tggggcgttaactgcatctg, tggtgaatgagtagcagcag, ctactcattgggatcatctt, tgctggtgatcctc ttgtag, actacagcttctttgggaca, tctcttgagcttggtgacaa, ttcttggggtcagcacagac, gatctcatttggttccgatc, aaggtgctg aagaccttagg, tttacgggtcaacttcacat, tagtggatgcattagcttca, ctcctacagaagtgcttgag, tagttcactgtcacactggt) with TAMRA dye (Biosearch Technologies, Inc.). Following the manufacturer’s instructions slides were thawed to room temperature and immersed in 3.7% formaldehyde in 1 X PBS for 10min. Slides were washed twice with 1X PBS for 2-5 minutes and permeabilized by incubation in 70% ethanol for 1 hour at room temperature. Slides were washed in wash buffer A (Biosearch Technologies Cat# SMF-WA1-60), followed by probes hybridization overnight at 37°C. Samples were counterstained with DAPI, rinsed in wash buffer B (Biosearch Technologies Cat# SMF-WB1-20), and coverslipped with Vectashield® Mounting Medium (Vector Laboratories Cat #H-1000).

Single-Molecule FISH Probes for mCherry mRNA

Check if the same lab product or an alternative is used in the 5 most similar protocols
We designed single-molecule FISH probes to detect mCherry-mRNA. For this we used the Stellaris FISH probe designer (LGC Biosearch Technologies; www.biosearchtech.com). The set of probes (25 probes) were designed to attach to the full length of mCherry RNA and were coupled to Quasar 670 (a Cy5 analog, LGC Biosearch Technologies). We also designed FISH probes to detect mRNA of endogenous yeast genes to convert TPM values from our 4tU RNA-sequencing data to integer numbers of RNA per cell. For this, we used probes for RPS3 (30 probes coupled to Quasar 670), RPL3 (48 probes coupled to Quasar 570, a Cy3 analog LGC Biosearch Technologies), RPB1 (48 probes coupled to Quasar 670) and RPB3 (40 probes coupled to Quasar 570). The excitation and emmission peaks of these fluorophores are ex. 548/em. 566 nm (Quasar 570) and ex. 647/em. 760 nm (Quasar 670).

RNA FISH and Immunofluorescence for TH17 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cy3-conjugated lncRNA-GM probes were designed by the Stellaris FISH Probe Designer (Biosearch Technologies). RNA FISH was performed as described previously (19 (link)). TH17 cells were fixed with fixation/permeabilization solution (eBioscience) for 15 min at room temperature, followed by hybridization with probes according to the Stellaris RNA FISH protocol.
For immunofluorescence analysis, naïve T and TH17 cells were fixed with fixation/permeabilization solution for 15 min at room temperature and then followed by incubation with anti-FOXO1A antibody (Abcam) or control antibody IgG (Cell Signaling Technology) and Alexa Fluor 647 anti-rabbit secondary antibody (Thermo Fisher Scientific). Images were obtained with a laser scanning confocal microscope (Leica TCS SP8) and analyzed by the LAS X software version 2.0.2.15022.

Anti-sense oligo probes tiling the mouse Hottip RNA were designed using the web tool from Stellaris FISH Probe Designer (https://www.biosearchtech.com/support/education/stellaris-rna-fish) Biosearch Technologies, CA, USA). Eleven biotinylated oligos were synthesized by Sigma-Aldrich (S6 Table). ChIRP was performed in limb mesenchymal cells as described previously[42 ]. RNA was isolated from 20% of the ChIRPed beads and used for RT-qPCR for Hottip, 7sk and Gapdh specific primers and rest of the sample was used to purify DNA and perform qPCR for Hoxa genes. Primer details are given in S2 Table.

Stellaris FISH Probes for C. elegans

Check if the same lab product or an alternative is used in the 5 most similar protocols
Custom Stellaris FISH probe sets were designed against the entire coding sequence of F19F10.1 (25 non-overlapping probes labeled with CAL Fluor Orange 560 Dye) and pal-1 (25 non-overlapping probes labeled with C3-Fluorescein Dye), using the Stellaris FISH Probe Designer (Biosearch Technologies, Inc, Petaluma, CA, USA). FISH was performed according to the protocol available on the Stellaris website for fixation of embryonic C. elegans material, with the following modification: all steps were performed in 1.5 mL Eppendorf tubes. Hybridization of two non-overlapping probe sets was performed using 125 nM of each probe set contemporaneously. Within 48 hr from completing the hybridization protocol, embryos were mounted on glass slides under #0 coverglass (85–115 µM thickness), supported on each corner by small amounts of plasticine to avoid crushing the embryos. Slides were imaged immediately after mounting with a Zeiss LSM 510 confocal microscope.

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.
