All experiments were performed under strict S1 conditions, following all relevant safety protocols. Given the sensitivity of the human cell lines we used, we placed great emphasis on controlled and well-designed workflows. All transfections were performed in our own transfection laboratory to ensure a high level of safety and compliance. Below you will find an overview of the cell lines submitted by us as a checkin and the specific safety measures: - HEK293T-3HA-CFTR. - The HEK293T-3HA-CFTR cell line is based on HEK293T cells expressing an additional tsA1609 allele of the SV40 large T antigen. This allele enables the replication of vectors containing the SV40 origin of replication. In addition to the native CFTR gene, which is not expressed in HEK cells, the HEK293T-3HA-CFTR cell line from Leuven carries another copy of the CFTR gene embedded in an expression cassette. This cassette contains a CMV promoter, which is derived from the human cytomegalovirus and is frequently used for the overexpression of genes in human cells. In addition, the cassette contains a puromycin resistance gene that is co-expressed with CFTR, allowing continuous selection of CFTR-expressing cells. + In our project, we paid attention to safety at every step, especially when working with specific cell lines [link Zellinien].

They are characterized by their fast division rate and high transfection efficiency, which makes them a popular model in biomedical research. For our studies, the basic HEK293 cells were provided to us by the Cellular and Molecular Biotechnology Group at Bielefeld University, headed by Prof. Dr. Kristian Müller. Prof. Dr. Müller is also one of the Principal Investigators of our team. We use this cell line in our proof-of-concept studies and for testing the Prime Editing Guide pegRNA (pegRNA) to evaluate the efficiency and functionality of our constructs. + </p> + <p> + <strong>HEK293T-3HA-CFTR cell line: </strong>The HEK293T-3HA-CFTR cell line is based on HEK293T cells expressing an additional tsA1609 allele of the SV40 large T antigen.

This mutation leads to a defective CFTR protein that impairs the normal function of the chloride channel. The cell line is therefore ideal for studying the effects of this mutation and for evaluating potential therapies for cystic fibrosis. -- GitLab
