High-throughput DNA sequencing is revolutionizing the study of cancer and enabling the measurement of the somatic mutations that drive cancer development. However, the resulting sequencing datasets are large and complex, obscuring the clinically important mutations in a background of errors, noise, and random mutations. Here, we review computational approaches to identify somatic mutations in cancer genome sequences and to distinguish the driver mutations that are responsible for cancer from random, passenger mutations. First, we describe approaches to detect somatic mutations from high-throughput DNA sequencing data, particularly for tumor samples that comprise heterogeneous populations of cells. Next, we review computational approaches that aim to predict driver mutations according to their frequency of occurrence in a cohort of samples, or according to their predicted functional impact on protein sequence or structure. Finally, we review techniques to identify recurrent combinations of somatic mutations, including approaches that examine mutations in known pathways or protein-interaction networks, as well as de novo approaches that identify combinations of mutations according to statistical patterns of mutual exclusivity. These techniques, coupled with advances in high-throughput DNA sequencing, are enabling precision medicine approaches to the diagnosis and treatment of cancer.

The rapid advances in high-throughput DNA sequencing technologies and their application to cancer genome sequencing has led to a proliferation of approaches to analyze the resulting data. Moreover, there are multiple signals in sequencing data that can be used to address the challenges listed above, and different computational methods use different combinations of these signals. This rapid pace of progress, the diversity of strategies and the lack, for the most part, of rigorous comparisons among different methods explain why a standard pipeline for the analysis of high-throughput cancer genome sequencing data has yet to emerge. Hence, we are able to include only a fraction of possible approaches. Moreover, we restrict attention to methods for DNA sequencing data and do not discuss the analysis of other high-throughput sequencing data, such as RNA sequencing data, that also provide key components for precision medicine[17].
The estimated BMR greatly affects the identification of recurrent mutations, as an estimate that is higher than the true value fails to identify recurrent mutations (false negatives), whereas an estimate that is lower than the true value would leads to false positives. Of course, if a driver gene is mutated in a very high percentage of samples (more than 20%, for example), even an inaccurate estimate of the BMR is sufficient to correctly identify such a gene as recurrently mutated. Thus, well-known cancer genes (such as TP53) are readily identified as recurrently mutated genes by all computational methods. The priority now is to identify rare driver mutations that are important for precision oncology. The tools that are currently available often report different rare mutations as drivers, and more work is needed in order to improve the sensitivity in the detection of rare driver mutations and to compare and combine the results from different tools[58]. In general, reporting rarely mutated genes as recurrently mutated with high confidence requires either better estimates of the BMR and/or much larger patient cohorts.
Genes and their protein products rarely act in isolation. Rather, they interact with other genes or proteins in various signaling, regulatory, and metabolic pathways, as well as in protein complexes. Cancer research over the past few decades has characterized a number of these key pathways and has provided information about how these pathways are perturbed by somatic mutation[1, 87]. At the same time, the complexity of this interacting network of genes or proteins presents a major confounding factor for identifying driver mutations in genes using statistical patterns of recurrence. For instance, if cancer progression requires the deregulation of a particular pathway (such as those involved in apoptosis) there are a large number of known and unknown genes whose mutation would perturb this pathway. While some of the genes in these pathways may be frequently altered, other genes may be mutated rarely in a collection of patients with a given cancer type. This idea explains the long tail phenomenon that is apparent from recent cancer genome studies: only a few genes are mutated frequently and many more are mutated at frequencies that are too low to be statistically significant[2]. Consequently, in order to identify rare driver mutations that are crucial for precision oncology, it is advantageous to identify groups or combinations of genes that are recurrently mutated.
AAV5 TAb assay precision: To assess inter- and intra-assay precision, two sets of QCs (at concentrations of HQC, LQC, and negative QC [(NQC]) were run on 30 plates over 10 days (three plates per day) by two analysts, and the coefficient of variation (CV) was determined. All analyses were performed on data normalized to the CC pool. Interassay precision values for HQC, LQC, and NQC were 14.3, 13.1, and 9.9% CV, respectively. Intra-assay precision values for HQC, LQC, and NQC were 4.6, 7.2, and 6.3% CV, respectively. Titer QC (TQC) precision was also assessed. Analyses were based on the same six curves used to determine assay sensitivity. Precision for TQC was 5.5% CV.
But that precision comes at a price. Oh, the price: The MSRP, and then whatever mangling the current market may wreak on it. The RTX 3080 Ti may be beautiful on the outside, and a 4K-gaming beast inside, but it doesn't generate quite enough extra performance over the non-Ti RTX 3080 to justify the big increase in MSRP. How that plays out in real world pricing is anyone's guess, but we don't expect the price proportions to be any prettier in its favor.
Sartorius lab balances are equipped to meet the highest standards of speed, reliability, compliance, and safety. Besides designing our balances to deliver the best weighing results, we at Sartorius focus even more on integrating them into your laboratory workflows to make your processes more efficient, reliable, and ergonomic. Sartorius laboratory balances offer high levels of accuracy and precision in analytical testing and quantitative analysis. Suitable for use in laboratories, manufacture according to pharmacopeias and quality control, as well as academic research and any other professional use.
The Cubis II platform is a completely configurable, high-performance portfolio of both lab weighing hardware and software. Cubis II is the only laboratory balance with fully customizable hardware, software, and connectivity. It offers modern user interfaces, pharmaceutical and GxP compliance, including data handling, data integrity and connectivity, ergonomic sample handling, easy process integration, and unlimited communication at the highest level of accuracy and precision.
The six different types of balances offer by Sartorius include: ultra-micro lab balance, micro lab balance, semi-micro lab balance, analytical lab balance, precision balances and scales, and high capacity balances and scales.
Some balances are equipped with internal motorized calibration function for an easy calibration by one touch. Internal calibration can be even easier if the balance is equipped with the isoCAL feature, where internal calibration will be launched automatically when environmental conditions change. This feature is very convenient to have in a micro, semi-micro, analytical or precision balance. Depending on the balance readability, usually for 4-, 5-, 6- and 7-digit balances it is launched every four hours, for lower resolution balances it is every six hours. However, time to time, external calibration is recommended as well. External calibration required more effort on the balance user. In case the calibration may need to be traceable for ISO purposes or to meet other requirement, certified weight should be used to calibrate the balance. A traceable calibration can be done through service from the balance manufacturers (calibration certification), or it can be done by the balance owner if they buy a certified weight which will be used in the calibration process.
