Linear motion system boosts lab automation

An advanced linear motion system is behind the performance of Singer Instruments' innovative biotech laboratory robot for pinning arrays of cells - the RoToR.

This benchtop automation is changing genetic, genome and cancer research by being able to manipulate over 200,000 yeast or bacteria cell samples per hour. This unprecedented speed - up to an order of magnitude faster than previous lab automation - is changing the way that many biotech labs work. One of Singer's robots often now typically services several laboratories, with users just booking short time slots on it for replicating, mating, re-arraying or backing up yeast or bacteria libraries.

RoToR is managed by a compact real-time controller from Baldor called NextMove ESB-2. This module controls the three axes of motion that perform RoToR's point-to-point pinning action, as well as a sample handling axis, interfacing to the machine's Windows-based graphical user interface, and all the I/O channels required.

Facilitating compliance with FDA guidance on suicidality assessment in clinical trials

ERT, a global provider of technology and services to the pharmaceutical, biotechnology and medical device industries, announced that its eC-SSRS (Electronic Columbia Suicide Severity Rating Scale) solution facilitates compliance with the newly introduced Food and Drug Administration (FDA) guidance document entitled "Suicidality: Prospective Assessment of Occurrence in Clinical Trials." A copy of this guidance can be downloaded from www.ert.com.

The recently released FDA guidance document is intended to assist sponsors in assessing the occurrence of treatment-related suicidality in clinical trials or drug and biological products. The guidance highlights the increasingly recognized importance of suicidality assessment in psychiatric and non-psychiatric drug trials and provides general principles for how best to achieve effective assessment during the drug development process. The document highlights the Columbia Suicide Severity Rating Scale (C-SSRS), which comprises a detailed interview as an approved assessment instrument.

The guidance intends to serve as a focus for continued discussions among the FDA, pharmaceutical sponsors, the academic community and the public.

ERT's eC-SSRS is an electronic self-rated version of the C-SSRS, which was developed in collaboration with the scale authors and provides a cost-effective method of proactively monitoring suicidality for trial sponsors. The solution was designed in anticipation of the FDA recommendations outlined in the newly released guidance document. Using interactive voice-response technology validated against the C-SSRS, the eC-SSRS is a fully structured interview providing standardized questions,  relevant follow-up questions, error-handling routines and scoring conventions. Helping to facilitate the FDA requirements, the eC-SSRS solution enables timely identification of possible risks and supplies rapid feedback to study sites for evaluation and follow-up.

Michael Federico, Vice President, ePRO, comments: "The release of the FDA document highlights the growing focus on treatment-related suicidality and the need to develop an accurate and effective method for use in clinical trials to enhance effective patient-safety monitoring. Bearing in mind the concerns regarding the burdens placed on investigators, ERT has created the eC-SSRS, a validated representation of the interview version C-SSRS, which facilitates the ability to reliably and reproducibly assess suicidality and comply with FDA guidance."

MALS detectors used in breakthrough virus research

Wyatt Technology Corporation, a leader in absolute macromolecular characterization instrumentation and software, has announced that its instruments were used in a recent landmark study that transforms the previous scientific understanding of immunity to viral diseases like the common cold, 'winter vomiting' and gastroenteritis.

The breakthrough research carried out by the United Kingdom's Medical Research Council Laboratory of Molecular Biology (MRC LMB) demonstrates the ability of tripartite motif-containing 21 (TRIM21) to neutralize viral infection. Wyatt Technology's Multi-Angle Light Scattering (MALS) detectors were used to monitor the interaction between TRIM21 and Immunoglobulin G (IgG).

Viruses such as the common cold, AIDS and some forms of cancer are among the hardest diseases to treat and are adept at avoiding recognition by changing their molecular patterns. Antibodies were originally thought to only offer extracellular protection and were helpless against the virus once it had entered the cytosol of a cell. However, the new study published by the MRC LMB shows that antibodies remain attached to viruses after cell infection and provide effective antiviral immunity.

KINAXO enters agreement with AstraZeneca

First FRET-based Elastase activity assay kit

AnaSpec has introduced the SensoLyte Green Elastase Assay Kit - the first FRET-based Elastase activity assay kit in the industry. This kit employs a natural substrate, elastin that is labelled with the 5-FAM fluorophore and the QXL 520 quencher.

Proteolytic cleavage of labelled elastin separates the donor from the quencher and yields brightly green fluorescence, which can be continuously monitored at excitation/emission (Ex/Em) = 488 nm/520 nm. Increase in fluorescence intensity is directly proportional to elastase activity. The kit can be used to continuously measure the kinetics of elastase activity. As well, this highly sensitive kit is homogeneous – it does not require any separation steps.

Elastases catalyze the hydrolysis of elastin, the chief constituent of elastic fibers that together with collagen determines the mechanical properties of connective tissue. Elastases have many other natural substrates these include proteoglycans, collagens and fibronectin.1-4 Implicated in many diseases such as pulmonary emphysema, cystic fibrosis, infections, inflammation and atherosclerosis, elastases are considered important drug targets.5

AnaSpec, Eurogentec Group also provides another green emitting elastase assay, the SensoLyte Rh110 Elastase Assay Kit. This assay uses a substrate that is labeled with a fluorogenic dye called Rh110 (rhodamine 110). Upon cleavage by elastase, the substrate generates free Rh110 fluorophore, which has a bright green fluorescence. Signal can be detected at Ex/Em =490/520 nm. The longer wavelength spectra and higher extinction coefficient of this kit and the SensoLyte Green Elastase kits provide greater sensitivity and less interference from other reaction components.
