Great work by Sanjay Boddul in the lab developing methods to study T cell receptors cloned from patients! The presented experimental pipeline enables rapid development of relevant humanized animal models for studying novel antigen-specific tolerance therapeutics.

In vitro and ex vivo functional characterization of human HLA-DRB1*04 restricted T cell receptors.
The Immune Epitope Database (IEDB) is a freely available resource funded by NIAID. It catalogs experimental data on antibody and T cell epitopes studied in humans, non-human primates, and other animal species in the context of infectious disease, allergy, autoimmunity and transplantation. The IEDB also hosts tools to assist in the prediction and analysis of epitopes.
It’s a version of LentiGuide-puro where Sudeepta Panda and Long Jiang added P2A-eGFP after PuroR, lac-mRFP in the stuffer, and a cloning site directly after the sgRNA scaffold.
The plasmid allows for both puro and eGFP selection and MOI determination. The lac-mRFP in the stuffer gives a simple visual quality control step when expanding in bacteria (red=stuffer, white=spacer successfully introduced). The cloning site allows for introducing e.g. UMIs.
Beautiful paper from the Elling and Zuber Labs on a novel score to predict sgRNA efficiency. Also including a website for sgRNA design based on the VBC score: https://www.vbc-score.org/ . Brought to my attention by shared first author Julian Jude.
