DNA laddering (left) visualised in an agarose gel by ethidium bromide staining. A 1 kb marker (middle) and control DNA (right) are included.. DNA laddering is a feature that can be observed when DNA fragments, resulting from Apoptosis DNA fragmentation are visualized after separation by gel electrophoresis the first described in 1980 by Andrew Wyllie at the University Edinburgh medical school ...
The apoptotic DNA fragmentation is being used as a marker of apoptosis and for identification of apoptotic cells either via the DNA laddering assay, [2] the TUNEL assay, [3] [4] or the by detection of cells with fractional DNA content ("sub G 1 cells") on DNA content frequency histograms e.g. as in the Nicoletti assay.
Apoptotic DNA fragmentation is a natural fragmentation that cells perform in apoptosis (programmed cell death). DNA fragmentation is a biochemical hallmark of apoptosis.In dying cells, DNA is cleaved by an endonuclease that fragments the chromatin into nucleosomal units, which are multiples of about 180-bp oligomers and appear as a DNA ladder when run on an agarose gel.

A molecular-weight size marker, also referred to as a protein ladder, DNA ladder, or RNA ladder, is a set of standards that are used to identify the approximate size of a molecule run on a gel during electrophoresis, using the principle that molecular weight is inversely proportional to migration rate through a gel matrix.

The first whole cancer genome to be sequenced was from cytogenetically normal acute myeloid leukaemia by Ley et al. in November 2008. [5] The first breast cancer tumor was sequenced by Shah et al. in October 2009, [6] the first lung and skin tumors by Pleasance et al. in January 2010, [7] [8] and the first prostate tumors by Berger et al. in ...

The mRNA-based disease diagnosis technologies have been applied to medical field widely in recent years, especially on early diagnosis of tumors (such as renal cell carcinoma, [2] hepatocellular carcinoma, [3] [4] breast cancer [5] and prostate cancer [6]). The technology can be applied to various types of samples depending on how easily the ...
