Our results prove that human ancient DNA can be retrieved from the fixative material of stored medical specimens and provide new options for the sampling of valuable curated collections. Method summary We compared the metagenomic content of historical tissues and their embedding liquid to retrieve DNA...

PCR-RFLP uses endonucleases to digest PCR products of regions with sequence polymorphisms. By using an endonuclease which recognizes and cleaves at the polymorphic sites, the digestion of a longer PCR fragment into smaller fragments will change the banding pattern. PCR-RFLP has been used for authent...
The procedure of processing the images of the microarray consists of addressing, segmentation, and information extraction. 1 Addressing Since the microarray spot images have many different sizes and shapes and some of the spots may not be located at the central position, addressing is essential to ...
Researchers use sterile excavation techniques, careful lab protocols and clean rooms, and perform PCR in rooms separate from where DNA extraction is performed. “This isn't to say that contamination isn't a problem, but one can at least incorporate the uncertainty associated with it into analyses...

Convolutional neural networks (CNNs) are automatic and adaptive representation learning and feature extraction algorithms that can be applied to predict unknown sequence profiles or motifs and functional activity discovery without pre-defining sequence features. Some TE classification algorithms are proposed ...
DNA extraction and bisulfite conversion PBMCs DNA was extracted with the TIANamp Genomic DNA Kit (Cat# DP304-03), according to the manufacturer’s instructions. DNA purity and concentration were estimated using a Quibt3.0 fluorometer (Thermo Fisher Scientific); then, 2 μl of DNA samples wer...
(hereafter referred to as Gram-positives), to adequately challenge the library construction and DNA extraction protocols. The DNA mock community consisted of an equimolar amount of genomic DNA of 20 different strains, with values (“ground truth”) for their relative abundances assigned by ...
