internship: Isolation of T-cell receptors specific for J chain derived peptides
-
Mar 2017 - Sep 2017
Master’s internship of six months at the department of experimental haematology at the Leiden University Medical Centre, working on: “Isolation of T-cell receptors specific for J chain derived peptides”. During this internship I learned how to isolate T-cells from PBMCs (peripheral blood mononuclear cells, MACS enrichment and single cell sorting using PE-labelled tetramers, stimulate and culture T-cell clones and recognition screening by using ELISA in a biosafety level 2 lab.
