Module Aims
This module aims: o To provide students with a good practical 'hands-on' experience of a sequential multistep protein purification scheme. o To provde a detailed understanding of the methods used in practical immumology. o To train students in practical analytical microbiology, particularly in regard to analysis of food and water samples and to introduce basic methods in microbial fermentation.

Learning Outcomes
Students will attain: o Practical experience of a sequential 'multistep' protein purification scheme. o Working knowledge of ion-exchange and gel filtration chromatography. o Practical experience of the isolation and analysis of antibodies. o Introduction to some basic antibody-based analytical methods. o Basic practical experience of HPLC analysis. o Technical ability to carry out batch and continuous microbial culture. o Ability to undertake microbial analsyis of food and water samples.
