Recently,a diatomaceous earth-based (19-22)method was used to isolate the plasmid or cosmid DNA from a cell lysate.The cell growth,lysis,and cleared lysate steps are performed as described above,but following DNA precipitation by polyethylene glycol,the DNA pellet is resuspended in RNase buffer ...
The method involves preparing a genomic library\ncomprising\ngenomic DNA fragments, and hybridizing one or more nucleic acid primers,\nselected from\na full-length cDNA, a 5' cDNA end, a 3'cDNA end, or a combination thereof, or\na full-\nlength mRNA, or portion thereof, or an RNA ...

Compositions and methods to isolate intact RNA that is substantially free of DNA, termed purified RNA. RNA from any source (e.g., human, other animals, plants, viruses, etc.) may be isolated. In one embodiment, the sample is treated with phenol at a pH less than 4.0 and purified RNA ...

Extracellular vesicles (EVs) are small membrane-bound bodies that are released into extracellular space by diverse cells, and are found in body fluids like blood, urine and saliva. EVs contain RNA, DNA and proteins, which can be biomarkers for diagnosis.
A major limitation in this evolving discipline is the hardship and the lack of standardization for already challenging techniques to isolate EVs. Technical advances have been accomplished in the field of isolation with improving knowledge and emerging novel technologies, including ultracentrifugation, ...
Promega offers several automated high-throughput options to isolate genomic DNA isolation from blood samples. Some laboratories, such as biobanks, have a desire to isolate DNA from large amounts of starting material (e.g., 10ml of blood). The ReliaPrep™ Large Volume HT gDNA Isolation System...
