Circulating cell free DNA: Preanalytical considerations
Clinica Chimica Acta, 2013Despite the growing interest in circulating cell-free DNA (ccfDNA) analysis in various clinical fields, especially oncology and prenatal diagnosis, few studies on sample handling have been reported and no analytical consensus is available. The lack of consistency between the various protocols for sample handling and the techniques used for ccfDNA ...

Annual Review of Microbiology, 1981
Abstract An inducible antibacterial activity is a main part of the immune system of the Cecropia moth and several other insects. The active material is a family of small proteins called cecropins. Sequence work shows that at least two of the cecropins originate from a gene duplication.

Toward sustainable, cell-free biomanufacturing
Current Opinion in Biotechnology, 2021Industrial biotechnology is an attractive approach to address the need for low-cost fuels and products from sustainable resources. Unfortunately, cells impose inherent limitations on the effective synthesis and release of target products. One key constraint is that cellular survival objectives often work against the production objectives of biochemical

Cell-free DNA (cfDNA) found in the plasma or serum is derived from multiple sources, including tumor cells. The fraction of cfDNA derived from tumor cells is termed circulating tumor DNA (ctDNA). Despite the low levels of ctDNA in normal cfDNA, advances in digital polymerase chain reaction (PCR) and next-generation sequencing (NGS) technologies have ...

Future wireless networks will have to manage billions of devices at once, and each one needs a high throughput to serve a range of applications, including speech, real-time video, high-definition video, and others. Due to the excessively high interference levels and poor performance of user equipment (UEs) at the cell boundary, cellular networks are ...

Cell-free protein synthesis systems
Biotechnology Advances, 1998Cell-free protein synthesis systems enable the direct in vitro expression of proteins from template DNA or RNA. Use of biochemical and bioengineering techniques has greatly improved the yields and productivities of cell-free systems. In some cases, the yields approach the in vivo levels.

Biosensing has precise sensitivity and high specificity, and the potential use of biosensor ranges from environmental monitoring, food safety, to disease diagnosis [1]. Biosensing is using the biological sensing element to detect some substances, include inorganic molecules, disease biomarkers, and others.

Cell-free DNA: Preanalytical variables
Clinica Chimica Acta, 2015Since the discovery of cell-free DNA (cfDNA) in human blood, most studies have focused on diagnostic and prognostic uses of these markers for solid tumors. Except for some prenatal tests and BEAMing, cfDNA analysis has not yet been translated to clinical practice and routine application appears distant. This can be attributed to overlapping factors: (i)

Cell-Free Membrane Protein Expression
2013Cell-free protein synthesis is advantageous for membrane protein production because of the potential lethality of membrane proteins synthesized in cell-based systems. Additionally the ability to adapt the membrane composition for each membrane protein increases the likelihood of functional expression.
