Zirconia bead mix

Manufactured by Benchmark Scientific
Sourced in United States

Zirconia bead mix is a laboratory equipment product used for sample preparation. It consists of small, high-density zirconia beads that are designed for efficient disruption and homogenization of various types of samples, such as tissues, cells, or microorganisms, in preparation for further analysis.

DNA was extracted using the QiAmp Fast DNA Stool Mini kit (Qiagen Ltd, West Sussex, UK). Collected samples were individually placed in 2-mL tubes prefilled with 0.1 mm silica and zirconia bead mix (Benchmark Scientific, Edison, USA), dissolved in 1 mL InhibitEX buffer (Qiagen Ltd, West Sussex, UK) and vortexed until homogenized. A bead-beating step (Beadbug microcentrifuge homogenizer, Benchmark Scientific, USA) was applied for 3 x 60 s at 5 m/s with 5-min rest in between. Total genomic DNA was eluted in sterile microcentrifuge tubes and quantified by Qubit Fluorimetric Quantitation (ThermoFisher Scientific Ltd, UK) as per manufacturer’s instructions. Metataxonomic sequencing (16S rRNA gene sequencing) was performed at Research & Testing RTL Genomics (Lubbock, TX, USA), using primers detecting the V1-V2 regions of the 16S rRNA gene plus bifidobacteria regions to generate 10,000 paired-ends reads on a Illumina MiSeq (Illumina, San Diego, USA.

Gut Microbiome Profiling by 16S rRNA

Check if the same lab product or an alternative is used in the 5 most similar protocols
A total of 29 scraped intestinal samples and 96 fecal pellets were individually placed in 2-mL tubes prefilled with 0.1 mm silica and zirconia bead mix (Benchmark Scientific, Edison, USA), dissolved in 1 mL InhibitEX buffer (Qiagen Ltd., West Sussex, UK) and vortexed until homogenized. A bead-beating step (Beadbug microcentrifuge homogenizer, Benchmark Scientific, USA) was applied for 3 × 60 s at 5 m/s with 5 min rest in-between. The DNA extraction has been performed with QiAmp Fast DNA Stool Mini kit (Qiagen Ltd., UK), following the manufacturer’s instruction. Total genomic DNA was eluted in sterile microcentrifuge tubes and quantified by Qubit Fluorimetric Quantitation (ThermoFisher Scientific Ltd., UK), following the manufacturer’s instructions. DNA aliquots were kept at − 20 °C until used. Sequencing of the variable regions of the 16S rRNA gene was performed at Research and Testing Laboratory LLC (Lubbock, Texas, USA). Primers used to amplify the V1–V2 regions of 16S rRNA gene were 28F (5′-GAGTTTGATCNTGGCTCAG-3′) and 388R (5′-TGCTGCCTCCCGTAGGAGT-3′). Sequencing was performed using an Illumina Miseq (Illumina, San Diego, USA), with 10K paired-end sequencing protocol.

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.
