Whatman turboblotter transfer system

Manufactured by GE Healthcare
Sourced in United States

The Whatman Turboblotter transfer system is a laboratory equipment designed for efficient blotting of proteins, nucleic acids, or other biomolecules from gels onto membranes. The system utilizes a high-speed airflow to facilitate the rapid and uniform transfer of biomolecules, helping to improve the quality and consistency of blotting results.

Northern Blot Analysis of ONECUT2 and GAPDH

Check if the same lab product or an alternative is used in the 5 most similar protocols
A published protocol was used (He and Green, 2013 (link)). In brief, 15 microG of total RNA was mixed with 2x RNA-loading dye (New England Biolab), incubated at 65℃ for 20 min, and run on a denaturing RNA gel (1.2% agarose, 1x MOPS buffer) at 90 V for 5 h, along with the ssRNA ladder (New England Biolabs). The RNA was transferred onto a nylon membrane using Whatman TurboBlotter transfer system (GE Healthcare) according to the manufacturer’s instruction. The membrane was then UV crosslinked. DNA probes were prepared using the PCR DIG Probe system (Millipore Sigma). cDNA from a human cell line was amplified by PCR using the primers for ONECUT2 (5′ GAG​TCT​GCC​CAA​CTA​CGG​TC-3′ and 5′- GCG​TTT​GCA​CGC​TGC​C-3′) and GAPDH (5′-CAG​CCT​CAA​GAT​CAT​CAG​CAA​TG-3′ and 5′-AAA​TGA​GCT​TGA​CAA​AGT​GGT​CG-3′).

Southern Blot Analysis of mtpA Disruption

Check if the same lab product or an alternative is used in the 5 most similar protocols
Southern blotting was carried out on a single mtpA transformant for confirmation of mtpA gene disruption. As shown in Fig. 2a, the hybridization probe was prepared by amplifying a part of the hph marker gene with primers 11–12 (Table 3) and labeled using a North2South chemiluminescent detection kit (Thermo Fisher Scientific). Genomic DNA of the transformant was digested by EcoRI and HindIII and hybridized with the probe. Southern blotting was then performed using Whatman Turboblotter transfer system (GE healthcare life sciences) and detected by using a Pierce Chemiluminescent Nucleic acid detection module Kit (Thermo scientific). The blot was imaged in Thermo ECL imager.

Southern Blot Analysis of TDR Transformants

Check if the same lab product or an alternative is used in the 5 most similar protocols
The hybridization probe for the southern blot analysis of the TDR transformants was designed to consist of a single fragment containing FADO, TprC terminator, tef1 promoter and FAR sequence, originating from the previously constructed expression vector (Fig. 3a). The DNA probe was biotin labeled by using Pierce North2South Biotin Random Prime Kit (Thermo Fisher Scientific, Rockford, IL, USA) according the manufacturer’s protocol. Genomic DNA of the transformants was extracted as described above and digested with restriction enzymes BamHI, PstI, and NdeI (all purchased from Thermo Scientific, Rockford, IL, USA). Southern blotting was carried out using Whatman Turboblotter transfer system (GE Healthcare Life Sciences, Pittsburg, PA, USA) and the nucleic acid detection was carried out by using Pierce Chemiluminescent Nucleic Acid Detection Module Kit (Thermo Fisher Scientific, Rockford, IL, USA), both according to the manufacturer’s 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.
