The successful candidate will work within the Molecular and Cellular Biology (MCB) group. Their 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. The post-holder will 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. This represents a unique opportunity to acquire a strong practical knowledge base in a broad range of highly desirable transgenic biology skills in a group recognised for its expertise and the quality of its output, or to make use of an existing skillset in a thriving environment. Additional training in a range of soft skills will be provided. Emphasis on particular techniques will vary according to service demand. Previous experience in embryo handling or mouse tissue dissection is desirable. Main Duties/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 Characterisation and quality control of genetically modified materials employing PCR- and ddPCR- based techniques and Nanopore sequencing 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. Working Relationships: Working as part of a team with the other cell culture and embryology team members. This includes developing ES cell and organoid lines and dissection of mouse tissues and staged embryos as directed by the cell culture laboratory manager. Working with a range of technical support staff, including highly trained post-doctoral technologists, to produce cellular and embryology-based work for the molecular and cellular biology group. Additional Information: Some flexible work patterns and paid weekend work may be required at the discretion of the supervisor and as part of a team rota. Person Specification Education/Qualifications/Training Required: Essential: BSc in Biological Sciences or in a related subject Understanding of genome engineering techniques (gene targeting, CRISPR-based tools) Desirable: Holder of a Home Office Personal Licence Previous Work Experience Required: Essential: Experience of working in a laboratory Some initial experience in basic techniques of molecular biology e.g. PCR, cloning, or qPCR Desirable: Previous work with genetically modified materials/animals/embryos Experience of handling sequencing data Evidence of quality focused work Knowledge and Experience: Essential: Understanding of basic molecular biology techniques (PCR, qPCR or dPCR) Understanding of basic cell culture techniques (media preparation, sterile conditions) Computer literacy is essential for the recording and communication of results Experience of work in sterile conditions Desirable: An understanding of genetic modification in laboratory animals Basic understanding/use of standard imaging techniques Some experience of gene expression analysis, histology techniques or microscopy Personal skills/Behaviours/Qualities: Essential: Organised and hard-working, with precision and a strong eye for detail Able to work well as part of a team, as well as independently Good communication skills, both written and verbal Further Information Equality & Diversity: The MRC values the diverse skills and experience of its employees and is committed to achieving equality of treatment for all.
