Emerging Markets
Globalization is increasing more and more — also in research. State-of-the-art
research is carried out not only in scientific hotspots such as the USA, Japan and
Western Europe. Scientists in South America, China and Africa are also working
on complex issues, therefore they need modern analysis systems. For this reason,
more and more regions are hosting special laboratory fairs that take into account
the needs of local scientists. South Africa and Vietnam are examples of such
future science locations. Messe München is organizing two special events in both
regions: Analytica Vietnam from April 3 to 5 and Analytica Lab Africa, held
for the first time from July 9 to 11. These two fairs will certainly bring the science
of the regions forward.

Controlling devices, recording, archiving and analyzing data — nothing works
in the laboratory without software. And even modern high-throughput methods
can’t play off their advantages without efficient software. But what does this mean
for laboratory software? Are cloud applications the key here or can artificial
intelligence or machine learning help with complex research and development
issues? Starting on page 24, our author provides an overview of the current trends

Constant monitoring of cells // Whether you need to assay cell health, monitor cloning steps or
the efficacy of chemotherapeutics, or even visualize specific interaction processes, cells are al-
ways at the focus in every biopharmaceutical lab. Innovative systems such as the Sartorius
IncuCyte S3 live cell analysis system enable you to perform real-time, continuous live cell analy-
sis and gain deeper insights — without ever removing your cell cultures from the incubator.

S3 can be operated within
a standard tissue culture
incubator that provides
precise control of the

system control allows

to be generated over a
period of more than two
weeks without having to
remove them from the

of becoming faster and more flexible, the company intends to sig-

and strengthen the Verbund.
Additionally, the company commits to keeping its greenhouse
gas emissions flat at the 2018 level until 2030 — even though they
are targeting considerable annual production growth. The target
includes planned major investments, such as the new Verbund site
in Guangdong province in southern China. In addition to the target
of CO2-neutral growth until 2030, BASF wants to generate
around 25 billion dollar in sales with Accelerator products in 2025.
