Fig. S1. Results of polymerase chain reaction (PCR) using universal primers targeting mycobacterium DNA: hsp65 short (hsp65S; 441 bp), long (hsp65L; ca.770 bp), rpoB short (rpoBS; ca.330bp), long (rpoBL; ca.450bp) genes and the 16S-23S spacer region (internal transcribed spacer (ITS); ca. 350 bp). Clear strong bands with hsp65L, rpoBS, and ITS primers proved the existence of mycobacteria DNA. I...

In many cells, the process of apoptosis is accompanied by endonuclease-mediated double-strand cleavage of DNA between nucleosomes, resulting in the production of discrete fragments of 200 bp or multiples thereof. To address the question of whether this endonuclease attack occurs randomly or nonrandomly along chromosomes, we first constructed chromosome fluorescence in situ hybridization probes ...

in this study the programmed cell death (apoptosis) of human neutrophilic granulocytes was investigated in the presence and absence of fetal calf serum (fcs), cycloheximide and actinomycin-d. the results show that when fcs is omitted from cultures, apart from a decrease in viability, the percentage of apoptotic cells and dna fragmentation increases. apoptosis is accelerated in serum withdrawal ...

Zerumbone is a cytotoxic compound isolated from the herbal plant, Zingiber zerumbet Smith, which exhibits antitumor activity [1-2], anti-inflammatory effects and possesses anti-proliferative potentials in a variety of cell lines [3-4]. DNA fragmentation indicates an early event of apoptosis leading to cell death due to the absence of new cellular proteins synthesizing for cell survival. Previou...

HSV is a large double stranded DNA virus, capable of causing a variety of diseases from the common cold sore to devastating encephalitis. Although DNA within the HSV virion does not contain any histone protein, within 1 h of infecting a cell and entering its nucleus the viral genome acquires some histone protein (nucleosomes). During lytic infection, partial micrococcal nuclease (MNase) digesti...

Many biochemical, biomedical, and material applications hinge on the ability to effectively separate purify nanoscale materials. Though this need is largely addressed with biological macromolecules using a variety of chromatographic electrophoretic purification techniques, such techniques are usually laborious, time-consuming, often require complex costly instalments that inaccessible most labo...

Modern biological tools of recombinant technology have tremendous potential to characterize DNA molecules with the choice of DNA ladders. Determination of molecular weight of linear and double stranded DNA fragments either on agarose or polyacrylamide gel is done extensively with the DNA ladders. The most popular DNA ladders available in the market range from less than 25bp to 40 kb or more. Am...
