Contract type: Permanent

Hours: Full time

About Us

The Mary Lyon Centre at MRC Harwell (MLC)is located in an expanding science and innovation park in Oxfordshire and is an internationally renowned centre at the forefront of genetics research. As the hub of the new National Mouse Genetics Network, the specialist facilities and capabilities of the MLC support a number of research groups across the UK to accelerate our understanding of human disease.

About the Role

We are recruiting a Research Assistant in Cellular Biology and Embryology to join our expanding team of molecular cell culture biologists and to provide technical support for the purpose of genome engineering, functional validation of engineered mutations and cell-based assays. Your activity will span a range of molecular biology and cell culture techniques.

This position is based within a long-established laboratory tasked with the generation and validation of embryonic stem (ES), organoid and immortalised cell lines, as well as embryo phenotyping. Cell culture is used to either generate genetically defined mouse lines or challenge human-relevant disease models at the Mary Lyon Centre. Mouse embryos and adult tissues are used for the functional analysis of genetic alterations. You will use existing skills or gain highly coveted expertise in cell culture and will be taught to implement a range of embryo phenotyping techniques in a fast-paced environment with a strong team focus.

We welcome candidates with a background in animal or human biology or related life sciences. Candidates with solely plant biology or microbiology background need not apply.

About You

You will need to have:

BSc in Biological Sciences or in a related subject
Understanding of genome engineering techniques (gene targeting, CRISPR-based tools)
Experience of working in a laboratory
Some initial experience in basic techniques of molecular biology e.g. PCR, cloning, or qPCR
Understanding of basic cell culture techniques (media preparation, sterile conditions)

Key Responsibilities

The culture of mouse embryonic fibroblast cells, immortalised cell lines, ES cells and organoid lines
Use of various electroporation techniques to develop novel ES cell lines with known genetic modifications and the quality control of those lines
Preparation of ES cells and organoid cell lines for micro-injection to generate mouse models.
Extraction of mouse tissues,
Sample management and communication of results internally

Other general duties required are to ensure the smooth running of a cellular biology laboratory, such as ordering reagents and other tasks that are shared with the rest of the team.

Benefits:

Choosing to come to work at the MRC (part of UK Research and Innovation (UKRI)) means that you will have access to a whole host of benefits, from a defined-benefit pension scheme and excellent holiday entitlement, to access to employee shopping/travel discounts and a salary sacrifice cycle-to-work scheme. In addition, you will have the opportunity to contribute to the work of a world-class medical research organisation.

How to Apply

If you are ready to take on this exciting role and be part of a team dedicated to ground-breaking research, we would love to hear from you.
