The PPP Unit is at the Institute of Biotechnology and biomedicine of the Autonomous University of Barcelona (IBB-UAB) and counts with the necessary facilities for the design, production and purification of recombinant proteins. This facility is coordinated by the Nanobiotechnology Group, leaded by Prof. Antonio Villaverde. It has both highly specialized personnel and the necessary equipment to offer an “tailored” service for the design, production and purification of recombinant proteins using both prokaryotic and eukaryotic expression systems. Its location allows this service to be linked with other complementary services available within the university (Cell Culture, Cytometry, Production of Antibodies, Microscopy, Proteomic, and Bioinformatic,X-ray crystallography, and the Microarray and Sequencing Services), as well as facilitating the management of subsequent uses of the produced protein.
Counts with a laboratory perfectly equipped for the bioproduction of proteins, other with all the necessary equipment for the molecular cloning, plus one lab for the purification and characterization, and finally one for cryopreservation.
The PPP Unit is also applying for the ISO9001 certification forstandard quality control system.
FOR THOSE SERVICES IDENTIFIED AS OUTSTANDING, AT LEAST 20% OF THEIR CAPACITY IS OPEN UNDER COMPETITIVE ACCESS. SEE ANNEX 1 OF ACCESS PROTOCOL FOR DETAILS ON % OF OPENNESS FOR EACH SERVICE

Researchers of NANBIOSIS Unit 1 and NANBIOSIS Unit 18, led by Prof Antoni Villaverde have published the article at the prestigious scintific magazine titled Collaborative membrane activity and receptor-dependent tumor cell targeting for precise nanoparticle delivery in CXCR4+ colorectal cancer The researchers have shown that the combination of cell-penetrating and tumor cell-targeting peptides dramatically enhances precise tumor accumulation of protein-only nanoparticles intended for selective drug delivery, in mouse models of human colorectal cancer. This fact is a step forward for the rational design of multifunctional protein nanomaterials for improved cancer therapies. Protein production has been partially performed by the ICTS NANBIOSIS U1, Protein Production Platform[...]
Cell-selective targeting is expected to enhance effectiveness and minimize side effects of cytotoxic agents. Functionalization of drugs or drug nanoconjugates with specific cell ligands allows receptor-mediated selective cell delivery. However, it is unclear whether the incorporation of an efficient ligand into a drug vehicle is sufficient to ensure proper biodistribution upon systemic administration, and also at which extent biophysical properties of the vehicle may contribute to the accumulation in target tissues during active targeting. To approach this issue, structural robustness of self-assembling, protein-only nanoparticles targeted to the tumoral marker CXCR4 is compromised by reducing the number of histidine residues (from[...]
Researchers from NANBIOSIS-CIBER-BBN have developed a new type of protein biomaterial that allows a continuous release over time of therapeutic proteins when administered subcutaneously in laboratory animals. These results are the result of the stable scientific collaboration between the researchers of NANBIOSIS Units 1 Protein Production Platform (PPP)and 18 Nanotoxicology Unit, led by Toni Villaverde and Ramón Mangues at the Institute of Biotechnology and Biomedicine of the Autonomous University of Barcelona (IBB-UAB) and the Institut About the Hospital de Sant Pau and has had the participation of the Institute of Biological and Technological Research of the National University of Córdoba-CONICET,[...]
Oligonucleotide-protein conjugates have important applications in biomedicine. Four units of NANBIOSIS have collaborated to come across with more simple and efficient methods for the preparation of these conjugates. In the publication of the research results, a new method is described in which a bifunctional linker is attached to thiol-oligonucleotide to generate a reactive intermediate that is used to link to the protein. Having similar conjugation efficacy compared with the classical method in which the bifunctional linker is attached first to the protein, this new approach produces significantly more active conjugates with higher batch to batch reproducibility. In a second approach,[...]
Researchers of NANBIOSIS Unit 1 and NANBIOSIS Unit 18, led by Ramón Mangues, have published the article titled CXCR4-targeted nanocarrier achieves highly selective tumor uptake in diffuse large B-cell lymphoma mouse models . One-third of diffuse large B-cell lymphoma patients are refractory to initial treatment or relapse after rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone chemotherapy. In these patients, CXCR4 overexpression (CXCR4+) associates with lower overall and disease-free survival. Nanomedicine pursues active targeting to selectively deliver antitumor agents to cancer cells, a novel approach that promises to revolutionize therapy by dramatically increasing drug concentration in target tumor cells. In the study carried out[...]
A study result of collaboration between researchers of two NANBIOSIS units managed to produce a potent antitumor effect in an animal model with non-Hodgkin lymphoma A non-Hodgkin’s lymphoma, NHL is a cancer that starts in white blood cells called lymphocytes, which are part of the body’s immune system. Lymphoma. NHL is a term that’s used for many different types of lymphoma that share some characteristics. The most prevalent type of non-Hodgkin lymphoma is called diffuse large B-cell lymphoma (LDCGB). Although there are treatments for this pathology, there are non-responders. This nanoparticle can be developed as a nanopharmaceutical, in order to introduce a new treatment, whic[...]
“Selectively humanized nanomedicines aimed at killing CXCR4 + tumor cells for the treatment of acute myeloid leukemia” is one of the Project awarded by La Marató TV3 Foundation and is participated by Dr. Antonio Villaverde, Estrategic of NANBIOSIS U1 Protein Production Platform (PPP) The main objective of the project is the design and validation of humanized protein nanoparticles for the targeted delivery of antitumoral drugs for the treatment of acute myeloid leukemia. This will be done by the generation of protein-based nanoconjugates that will be targeted to the cytokine receptor CXCR4, overexpressed in this human neoplasia. The drugs will consist[...]
