Insect cell-based impedance biosensors: a novel technique to monitor the toxicity of environmental pollutants
Abstract Cell biosensors are currently emerging as novel, sensitive techniques to monitor the toxicity of environmental pollutants. Here, we have developed electric cell-substrate impedance sensing (ECIS) for on-line monitoring of the behavior of insect cells. Cells were cultured on a microarray of eight small gold electrodes, deposited on the bottom of tissue culture wells. Upon inoculation, ...

G100 portable CO2 incubator analyser for incubators gas readings
The Geotech G100, which measures CO2 from 0-20%, is used to demonstrate accurate and repeatable CO2 readings of the atmosphere inside incubators. In just a few seconds an embryologist is able to take a reading from various incubators, all of which will have a different means of sampling the air inside an incubator, without fully opening the inner door and adversely affecting the environment. It ...

S-adenosylmethionine and methylthioadenosine boost cellular productivities of antibody forming CHO cells
Product titers from Chinese hamster ovary (CHO) processes have increased steadily over the past decade, with reports from fed-batch processes now exceeding 5 g/L. Several approaches are being implemented for titer increases based mostly on volumetric productivity by supporting high viable cell densities (VCD). Another variable to focus on is increasing cell-specific productivity (CSP). CSP ...

Air uality in IVF Labs
Since the birth of the first baby from in-vitro fertilisation (IVF) in 1978, Assisted Reproductive Technology (ART) has grown in importance as techniques and success rates have continued to improve. Put simply, IVF involves mixing sperm and egg in a lab to create an embryo which is then replaced in a woman's womb to develop normally with success being measured in terms of live births. All cells, ...
