Isolation of E. coli Chromosomal DNAThis experiment containsreagents for ten groups toperform the isolation of chro- mosomal DNA. The same re- agents can be used for twenty isolations if supplementedwith additional tubes, pipets and spooling rods.Storage: See Page...
In this experiment, a method for isolating total DNA from the mulberry leaves was tested. Materials and methods: The procedure according to Murray and Thompson (1980) was applied to isolate total DNA from mulberry leaves, and other techniques used in this experiment were basically according to ...
The fragment, designated as pY-80, was proven with an in situ hybridization experiment to have originated from the Ypll.2-Ypter region. Its 2,808 bp section was sequenced. The polymerase chain reaction proceeded with oligonucleotides flanking a 666 bp Pstl-EcoRI fragment of the sequence as ...
A simple,rapid genetic DNA extraction procedure by improving the CTAB(cetyltrimethyl ammonium bromide) method has been established due to high quantity of phenol and polysaccharide contained in cotton,thus genetic DNA of cotton with high purity can be obtained.The optimized system and experimental prog...

while DNA loops of enhancer-gene interactions are generally more celltype-specific11,12. Recent studies identified specific DNA loops organized by CCCTC-binding factor (CTCF) and cohesin; these loops, called insulated neighborhoods, are local structures within TADs that encompass most enhancer-promoter...
Therefore, it is essential to conduct a preliminary experiment to determine appropriate inhibitors and their concentrations (Pan et al., 2019). It is also important to include appropriate controls (e.g., bacterial + fungal inhibitors, no inhibitors) to evaluate the occurrence of abiotic NO3−/...
The invention provides a method and kit for the separation and purification of cellular components including polar and non-polar metabolites, genomic DNA, RNA and proteins from a single biological sample where two steps of lysis of the cells are performed sequentially, before and after a metabolite...
