Researcher looking for degree of doctor

In nature, there are a few exceptions of functional antibodies lacking the light chains, known as single domain antibodies (HCAb). They are derivates of bona fide IgG and occur in the entire Camilidae family, nurse shark, wobbegong, and perhaps spotted ratfish. The family of camelids comprises camels, dromedars, llamas, vicuñas, guanaco and alpacas. The antigen-binding fragment of an HCAb contains a single variable VHH domain consisting of 3 hypervariable regions. When isolated, the VHH domain is also known as Nanobody. The target-specific Nanobodies derived from HCAbs of camelids are generally rapidly obtained briefly after immunization with the target protein plus adjuvant. Chile is a country with a huge biotechnological potential. In this application, we like to exploit the optimal conditions for camelid maintenance and its peculiar immune system to develop and produce recombinant antibody fragments of alpacas, known as Nanobodies. Over the last year, we have implemented the immunisation of Alpacas the laboratory for medical biotechnology at the Austral University of Chile, supported by the local government FICR funding, the European Union and Latino America and Caribbean organization in Health and now the FONDEF IdeA focussing on the development of economically attractive antibodies. Here, we aim to produce Nanobodies (small and recombinant single chain antibodies from alpacas) against post-translational modifications including epigenetic marks and members of the Ubiquitin-proteasome system. The generation of molecular tools for both pathways will be extremely useful; therefore this initiative is strongly supported by an international group of well-known experts on the study of post-translational modifications.

Requirements to apply:

  • Profesional: bioquímico, biotecnólogo o carreras afines.
  • Grado: Doctorado en ciencias biológicas o bioquímica
  • Requisito esencial: Experiencia con proteínas recombinantes, purificación, determinación de interaccione y afinidades.
  • Office skills: excellent technical abilities, enthusiasm, responsibility, rigour and commitment to work in a team and frustration tolerance.
  • Experiencia laboral: Indispensable (amplia experiencia técnicas bioquímica modernas para medición de interacción entre proteínas, expresión de proteínas recombinantes y Biología molecular), deseable (conocimientos en bio-negocios o conocimientos en Ubiquitinproteasome system, UPS)

The work involves:

  • Generation of Nanobodies involving cloning, production and purification of recombinant proteins, immunization of alpacas, isolation of lymphocytes generation of phagedisplay and bacterial display libraries, screening libraries, validation of antibodies and mostly quantitative analysis of interaction.
  • Handling of alpacas, support in immunization, cutting and shearing, etc...
  • Participate in the training of undergraduate and graduate students
