For basal CDK6 thermal stability assay, cells resuspended in 1 ml PBS containing protease inhibitor cocktail (Roche) were aliquoted with 100 μl cell suspension each into nine PCR tubes (~ 3 x 106 cells). Heat the PCR tubes at different temperature endpoints (35-59 °C) for 3 min in the Veriti 96-well thermal cycler (Thermo Fisher). Remove and incubate the tubes at room temperature for 3 min. Snap-freeze the samples immediately in liquid nitrogen. Freeze and thaw the cells three times using liquid nitrogen and a thermal cycler at 25 °C. Cell lysates were centrifuged at 20,000 x g for 15 min at 4 °C. Supernatants were collected for Western blots.
For PB or MS140-ve-induced thermal shift assay, cells were treated with 1 μM PB or 15 μM MS140-Ve for 2 hr. Cells resuspended in PBS containing protease inhibitor cocktail (Roche) were aliquoted with 100 μl cell suspension each into nine PCR tubes. Samples were heated at different temperature endpoints for 3 min using the Veriti 96-well thermal cycler (Thermo Fisher), followed by incubation at room temperature for 3 min and snap-freezing in liquid nitrogen. After three freeze and thaw cycles, samples were centrifuged at 20,000 x g for 15 min at 4 °C. Supernatants were collected for Western blot analysis.

Amplicon libraries were prepared as described by the Illumina protocol [25 ]. Briefly, a PCR of 25 cycles was performed to amplify the V3–V4 region of the 16S rRNA gene prior to the incorporation of the Illumina overhang adapters (Second PCR: 10 cycles) using 2.5 µL of DNA sample (5 ng/µL), 0.5 µL of each primer, and 12.5 µL of 2x KAPA HiFi Hotstart ReadyMix (Kapa Biosystems, Merck, Darmstadt, Germany). Bacterial communities were assessed using universal primers (Bac341F: CCT ACG GGN GGC WGC AG and Bac805R: GAC TAC HVG GGT ATC TAA TCC) [26 (link)] covering the V3–V4 regions of the 16S rRNA gene. The third PCR amplification (8 cycles) was carried out using Nextera XT index primers (Illumina, San Diego, CA, USA). Amplifications were conducted on a Veriti® 96-Well Thermal Cycler (Applied Biosystems®, Thermo Scientific, Waltham, MA, USA). The PCR products were purified with AMPure XP beads and Veriti® 96-Well Thermal Cycler (Applied Biosystems®, Thermo Scientific, Waltham, MA, USA), as described in the protocol. Amplicon libraries were then sequenced on the Illumina MiSeq (Illumina, San Diego, CA, USA), generating 2 × 300 bp paired-end reads.

Check if the same lab product or an alternative is used in the 5 most similar protocols
First, an annealing reaction of linker DNA-A (or -B) with the complementary spacer DNA in a phosphate buffer solution containing NaCl was conducted on a Veriti 96-Well Thermal Cycler (Applied Biosystems, Waltham, MA, USA) by incubating the mixture at 95 1C for 5 min and cooling to 25 1C. The linker DNA and DNA-AuNPs were then mixed in a phosphate buffer solution with 0.5 M NaCl (for 13 nm DNA-AuNPs) or with 0.25 M NaCl (for 23 nm DNA-AuNPs). For the 23 nm DNA-AuNPs, 6.5 mM HEPES and 22 mM potassium acetate were also contained in the buffer (final concentration). The amount of linker DNA was 25-100 equivalents per particle (for 13 nm DNA-AuNP) or 200 equivalents per particle (for 23 nm DNA-AuNP). The mixture was slowly cooled over 3 days from 65 1C to 25 1C in an incubator (IS401; Yamato Scientific Co., Ltd, Tokyo, Japan) or thermal cycler (Veriti 96-Well Thermal Cycler (Applied Biosystems) or T100 Thermal Cycler (Bio-Rad Laboratories, Inc., Hercules, CA, USA)).

A total of 1500 genomic and transcript-associated SSR markers previously published for common carp [73 (link), 74 (link)] were also used for initial segregation screening in the mapping family. Polymorphic loci segregated in either female or male parents were genotyped in the progeny through PCR amplification. PCR was performed on a veritiTM 96 well thermal cycler (Applied Biosystems, USA) with a total volume of 12.5 μl, containing 30 ng template DNA, 1.25 μl 10× PCR buffer (TaKaRa, Japan), 0.25 U Taq DNA polymerase (TaKaRa, Japan), 50 μM each dNTP, 0.2 μM each primer and water to the final volume. The thermal cycling was programmed as follows: 5 min at 94 °C, followed by 37 cycles of 94 °C for 30 s, 35 s at appropriate annealing temperature, and 72 °C for 40 s, and the last extension at 72 °C for 10 min.

Total RNA was extracted from thyroid tissues and cultured thyroid cells with Trizol reagent (#9109; TaKaRa, Japan), and RNA concentration was determined on a Nanodrop 2000C spectrophotometer (Nano Drop Technologies, USA). Samples with an OD260/OD280 ratio ranging between 1.8 and 2.0 were used for experiments. Reverse transcription reactions were carried out on a VeritiTM 96-well Thermal Cycler (AB Applied Biosystems, Singapore) with 1,000 ng RNA per sample and a 5 × PrimeScript RT reagent kit (#036A; TaKaRa, Japan). PCR amplifications were performed on a LightCycler 480 Real-Time PCR System (Roche, Switzerland) using a SYBR Premix Ex Taq™ II kit (#820A; TaKaRa, Japan), and GAPDH was used as an internal reference. Primers were synthesized by TaKaRa Biotech (specific sequences are shown in Table 1). Each sample was analyzed in duplicate. A melting curve was generated during amplification to verify the absence of primer dimers or incorrectly paired products. Relative mRNA expression levels of the target genes were calculated using the 2−ΔCp method after they were corrected based on GAPDH expression.

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.
