Dot och slot blotting av dna

Apr 27, 2011 Telomere DNA content has also been measured in slot/dot blot analysis by normalizing for alphoid centromere repeats ( 16 , 17 ). However, the

VOL. 30, 1992 on January 21, 2021 by guest Dot and slot blotting are simple techniques for immobilizing bulk unfractionated DNA on a nitrocellulose or nylon membrane. Hybridization analysis can then be carried out to determine the relative abundance of target sequences in the blotted DNA preparations. Dot and slot blots differ only in the geometry of the blot, a series of spots giving a hybridization pattern that is amenable to analysis by densitometric scanning.

It represents a simplification of the western blot method, with the exception that the proteins to be detected are not first separated by electrophoresis. Instead, the sample is applied directly on a membrane in a single spot, and the blotting procedure is performed. Dot blots and slot blots are also a very useful variation on the typical Western blot. They do not require gel electrophoresis, so there is no separation of proteins by size. Instead, the target protein or cell lysate mixture is added directly onto the surface of the nitrocellulose or PVDF membrane.

The most common blot applications used in modern laboratories are Northern blots, Southern blots and dot/slot blots. Regardless of the type of blot, the principles of probe synthesis, hybridization, washing and detection are the same. Ambion has invested substantial research efforts into understanding and overcoming the limitations of each of Dot and slot blot hybridization Often it is informative to quantify the abundance of a certain RNA or DNA in the extracted nucleic acid mixture by dot blot or slot blot hybridization without prior digestion and electrophoresis. In the procedure, the nucleic acid mixture is blotted to a membrane where the hybridization is carried out.

The procedure of dot blotting starts with taking an aqueous solution of the targeted DNA, such as total human genomic DNA, and then spotting it onto a nitrocellulose or nylon membrane where it is allowed to dry. Another technique, called slot-blotting in which the DNA is pipetted out through an individual slot into a template as per the

Samples are then diluted to 100 μl in the same buffer and filtered through nitrocellulose filters (0.45 μm) using either a dot blot or slot blot apparatus. Prior to filtering, the nitrocellulose filters are prepared by presoaking the membrane in 0.4 M KOH for 10 min, rinsing with H 2 O until the pH is neutral, and equilibrating in Binding Provides DNA for PCR, RT-PCR, Southern blotting, SNP and STR genotyping, and pharmacogenomics' research. Gives consistent and high yields. DNA can be purified from up to 25 mg tissue or from up to 200 ul fluid in 20 minutes. QIAamp DNA Mini can be automated on the QIAcube [35, 36] AllPrep DNA/RNA Mini (QIAGEN) Cell or tissue sample DNA was quantified with PicoGreen (ThermoFisher) using a TBS-380 fluorimeter (Turner Biosystems). Note that 100 ng of DNA was analyzed by slot blotting with rat anti–cisplatin-modified DNA antibody (Abcam, ab103261) as described . In the present study we evaluated the GST-rTp47, GST-rTp17 and GST-rTp15 antigens in an immuno-slot blot (IB) assay for the diagnosis of syphilis. For cloning, the DNA fragments of Tp47, Tp17 and Tp15 were prepared by PCR using the chromosomal DNA of T. pallidum subsp. pallidum (Nichols strain) as template. The open reading frame (ORF) encoding copy number, also verified in slot-blot assays (less than 10 BlATE-1 copies per haploid genome, data not shown). In contrast, the hybridization pattern of the EcoRI-restricted genomic DNA (Fig. 3A, odd lanes) rendered a strong 870-nt band, suggesting that the two internal EcoRI sites and the intervening distance were highly conserved. 3.2.
