Cutting-edge environments

As one of our students, you will be taught in modern laboratories during your practical sessions. These are large and well-equipped, containing up-to-date equipment which gives you valuable experience of using a professional facility.

Final-year and postgraduate research projects are carried out using our academic research laboratories. These were renovated as part of the ongoing expansion of our School and its facilities.

Our aim is to provide you with state-of-the-art equipment and ensure your studies are as relevant and productive as possible.

Examples of our Facilities

STEM Centre

As well as modern breakout rooms, computer facilities and Bytes Cafe, the new STEM Centre is used for many undergraduate practicals and Masters classes.

This enormous laboratory space has new digital microscopes, integrated with the latest audio-visual equipment and displays, as well as Class II microbiological safety cabinets for cell culture, and the latest spectroscopy technology.

The STEM Centre and laboratory spaces are wheelchair accessible, and our lab space has height-adjustable, DDA compliant work benches.

Bioimaging Facility

We have high-end and routine microscopes in darkrooms, workstations for image processing and analysis, and a lab for sample preparation. Using mainly fluorescence microscopy, we are well-equipped to carry out fluorescent protein localisation, morphology and quantified phenotype analysis from single cells to tissues. Areas of expertise are live cell imaging, large-sample macroscopy, and fluorescent-protein-based biosensors.

We also develop our own instruments, algorithms for computational image analysis, and sample preparation techniques. We have a FACS BD Accuri C6 flow cytometer equipped with a blue and red laser, two light scatter detectors, and four fluorescence detectors with optical filters optimised for the detection of fluorochromes, including FITC, PE, PerCP, and APC, and can also detect many variants of fluorescent proteins, such as GFP, YFP, and mCherry.

The School is also in the process of purchasing a new FACS-sorter for separation and isolation of primary human cells and genetically modified cells. The sorter will support applications from all research groups in the School of Life Sciences such as CRISPR/Cas9, purification of pure cancer cell populations for further analysis, advance immunology and isolation of plant cell organelles.

Bioinformatics and Computational Biology

The department now has two 'dry laboratories' and a high-performance computing cluster accessible on and off campus (via VPN), and is configured for both interactive and batch use. The cluster currently has 128 processor cores and a total of 2 Tb of memory, plus 100 Tb of storage, and a separate webserver. Expansion of this system is ongoing.

A broad range of bioinformatics software is installed including all commonly used DNA sequence analysis software and numerous R packages. There is a Galaxy instance on the webserver for teaching purposes. The cluster is in use by numerous postgraduate students, staff and some undergraduate students and actively supported by a dedicated staff member and the genomics group.

BBSRC ALERT Funded Equipment

We are very pleased to have a number of pieces of equipment funded via the Biotechnology and Biological Sciences Research Council (BBSRC) on behalf of UK Research and Innovation.

The equipment listed below is accessible to academic, public, and private sector users to support development of high-quality research. For more information or to enquire about usage please contact sls-res-manager@essex.ac.uk

EPR Spectrometer – the key machine in our Biomedical EPR Facility

Funded from the BBSRC ALERT award, the Bruker E500 CW X-band EPR spectrometer is used by many national and international users as part of our Biomedical EPR Facility.

This equipment allows for detecting paramagnetic states of biologically significant molecules, such as, proteins, enzymes, and many other molecules, whether small or large, isolated or in complex environments such as cells or tissues. The measurements are possible at both low and room temperatures, including solidly frozen samples at as low temperatures as 4 K, as well as of liquid samples at room temperatures.

Lightsheet Microscope

In collaboration with Eastern Arc Academic Research Consortium (EARC), a grant was awarded for a state-of-the-art lightsheet microscope which enables scientists to observe delicate cells, tissues and whole organisms without damaging them with intense light. This is used in combination with cutting-edge software to address new and exciting biological questions in biomedical and environmental research. It forms part of the Imaging Platform Alliance (IPA) between the EARC universities.

Use of IPA equipment can be applied for through EARC.

Dynamic Plant Phenotyping for future proofing crop productivity (DynSCREEN)

BBSRC ALERT funding has enabled the development of a state-of-the-art phenotyping platform DynSCREEN for Dynamic Plant Phenotyping for future proofing crop productivity. This houses a PSI Plantscreen™ Robotic XYZ System which enables high-precision automated phenotyping of plants for a range of sizes. It includes a range of specialised cameras which can capture spatial and temporal images of plants under various conditions and use these to determine key traits.

This system is part of our Smart Technology Experimental Plant Suite (STEPS), a novel dynamic indoor environment, capable of mimicking any outdoor environment both now and in the future DynSCREEN represents critical investment for UK plant phenotyping and is aimed at promoting collaboration.

Dianthus (NanoTemper)

Dianthus (NanoTemper) is the first ever screening platform to use two biophysical modalities, Temperature Related Intensity Change (TRIC) and Spectral Shift (SS), to measure the strength of molecular interactions (TRICSS).

It has unique features that allow for increased sensitivity in the detection of true molecular interactions:

  • measures affinities between a wide range of fluorescent labelled targets (protein, peptide antibody, DNA, RNA and aptamer) and an even wider range of ligands (protein, peptide antibody, DNA, RNA, aptamer, compounds, fragments, ions, virus like or other particles).
  • generates a significantly lower percentage of false positive results compared to other biophysical techniques and detects a wide range of physiological binding affinities (pM to mM).
  • no immobilisation is required (overcoming Biolayer Interferometry (BLI) and Surface Plasmon Resonance (SPR) limitations), and it differentiates between binding and aggregation (overcoming Isothermal Titration Calorimetry (ITC) limitations).
  • All measurements are in solution and mass-independent and therefore ideal for fragment library screening.
